Anxiety & Pulse

Author
by 

According to the National Institutes of Health (NIH), a rapid pulse or arrhythmia may occur during episodes of anxiety. A normal pulse or heart rate is between 60-100 beats per minute. If an individual has a resting heart rate faster than 100 beats, they may be experiencing tachycardia, which can result from a variety of medical conditions, and is often associated with stress, anxiety, and fear.

Stress and Anxiety

The National Institutes of Health note that stress and anxiety result from a sensation of nervousness, worry, or fear. When worry and anxiety build, they place stress on an individual's body, producing higher levels of stress hormones. These hormones cause symptoms such as restlessness, sleeplessness, and fatigue, and this process will often cause a cycle that produces higher levels of anxiety.

Panic Attacks

A panic attack is strong physical response to a fear or worry. The National Institutes of Health note that many individuals who have panic attacks may mistake them for heart attacks because they have increased pulse that is often accompanied with chest pain or dizziness. A person experiencing a panic attack may suddenly feel that his heart is racing and will feel an intense sense of fear or numbness in the hands or feet. The National Institutes of Health notes that panic attacks can occur without a clear trigger, so patients often do not realize they are experiencing anxiety and will feel that they are having a medical emergency.

Risk Factors for Anxiety and Rapid Heart Rate

The National Institutes of Health notes that genetics play an important role in anxiety and panic attacks. Although it is unclear exactly what causes some individuals to experience anxiety disorders, medical experts have linked these disorders to substance abuse, alcohol abuse, and depression. Consumption of alcohol may lower an individual's levels of vitamin B-12, and this vitamin deficiency is often linked to higher levels of anxiety and stress.

Exams and Tests

A individual who is experiencing rapid heart rate may have a medical exam and diagnostic tests such as electrocardiogram or an echocardiogram. These tests diagnose any heart issues that may be causing the palpitations. Doctors at the National Institutes of Health note that individuals with healthy heart function may experience palpitations, and in many cases these episodes are linked to anxiety and stress rather than heart disease or heart attack.

Treatment of Anxiety and Rapid Heart Rate

According to the National Institutes of Health, individuals with anxiety and panic attacks can prevent episodes of irregular heart rate by avoiding stimulants such as caffeine, eating a healthy diet, not smoking, and using stress management techniques such as deep breathing and meditation. In some cases patients may benefit from psychotherapy to help them identify the sources of stress in their lives. Experts at the National Institutes of Health also note that a variety of psychotropic medications can be used to control anxiety and reduce incidence of panic attacks and rapid heart rate.

What Causes Fast Heart Rate in Cancer Patients?

A normal heart rate is between 60 and 100 beats per minute. Tachycardia, the medical term for a rapid heart rate, is defined as a heart rate of greater than 100 beats per minute. During exercise or vigorous activity, the heart beats faster to provide the body with the increased oxygen it needs during exertion. However, non-exercise related tachycardia can have many causes, some of which frequently are experienced by cancer patients.

Anemia

Many cancer patients receive chemotherapy as part of their treatment, and unfortunately, the majority of cancer patients on chemotherapy develop anemia during the course of their treatment, notes the OncoLink, a service of the Abramson Cancer Center of the University of Pennsylvania. A large study conducted across 24 nations by the European Cancer Anaemia Survey in 2006 demonstrated that approximately 83 percent of patients who received chemotherapy demonstrated anemia, which was defined as a hemoglobin levels below 12.0 g/dL, notes the primary author of the study, Dr. Barrett-Lee. One of the symptoms of anemia is rapid heart rate, as the body tries to compensate for the decreased amount of oxygen that can be carried by the blood, due to decreased hemoglobin.

Medications and Drugs

Some of the chemotherapy drugs administered have side effects that include tachycardia, or rapid heart rate. Trisenox, or arsenic trioxide, is used to treat acute promyelocytic leukemia, after other chemotherapies have been ineffective, that can cause rapid heart rate, notes ChemoCare. Rituxin, or Rituximap, is another chemotherapy drug that can cause cardiotoxicity, which often manifests as irregular and/or fast heart rate, notes the Oncology Channel. In addition, excessive consumption of caffeine or alcohol can also cause rapid heart rate, as can smoking, notes MayoClinic.com.

Recreational drugs like marijuana can increase heart rate by as much as 50 percent, depending on the amount of THC, notes the Missouri Department of Mental Health. Marijuana is sometimes used medicinally by cancer patients to combat nausea and vomiting.

Concurrent Medical Conditions

More than one disease or condition may be present at a given time, and they can also contribute to tachycardia in cancer patients. For example, heart disease, congenital heart defects or abnormalities, high blood pressure, also known as hypertension, and an overactive thyroid, also known as hyperthyroidism, are all causes of rapid heart rate, according to MayoClinic.com. According to Chemocare, low blood pressure, lung infections, such as pneumonia, and blood infections also may cause tachycardia. Therefore, cancer patients who have any of these medical conditions concurrently could be more likely to experience rapid heart rate.

Why Is My Heart Rate Higher Than Normal?

Author
by 

Heart rate is controlled by electrical signals sent through heart tissue. A healthy adult heart rate is 60 to 100 beats per minute at rest. Many people, however, experience an elevated heart rate and for a variety of reasons. A chronic high heart rate can disrupt normal heart function severely, increasing the risk of a stoke or heart attack.

Symptoms

Rapid heart rate is inefficient for the body because it does not pump the blood properly. Some side effects you may experience with a rapid heart rate include dizziness, lightheadedness, fainting, chest pain, shortness of breath or heart palpitations. Some people may only experience a rapid heart rate and not have any other symptoms. You should see a doctor if you experience symptoms. Your doctor may suggest an EKG to see if you have tachycardia or any other problems with your heart.

Causes

Exercise is a common cause of rapid heart rate. Your heart rate should elevate during exercise, but it may be a problem if your heart rate remains elevated for more than 10 minutes after you finish your workout. Dehydration can also cause a faster heart rate. The lack of water in your body will decrease your blood volume and therefore lower the amount of blood your heart is able to circulate with each beat. This causes the heart to beat more rapidly to circulate more blood. Stimulants like caffeine, ephedrine, nicotine and certain decongestants can all cause rapid heart rate, as can medical conditions such as high stress, anxiety, anemia, overactive thyroid, anorexia, diabetes and illnesses causing a fever.

Treatment

Your doctor may suggest you manipulate the vagal nerve, which helps regulate your heartbeat, by coughing, placing an ice pack on your face or bearing down as if having a bowel movement. This can help return your rapid heart rate to a more normal one. If vagal nerve manipulations do not work, your doctor may recommend an anti-arrhythmic medication for you to take when you experience an episode of rapid heart beats.

Prevention

Drink plenty of water during your workout. This will help you stay hydrated and ensure your blood volume remains high. Drink only one cup of coffee or switch to decaf if you find caffeine is the cause of your increased heart rate. Avoid taking diet pills or cold medications containing ephedrine if these are the cause of your rapid heart rate.

High Heart Rate Dangers

Author

Overview

The heart rate, or pulse rate, is the rate at which the heart beats. A normal heart rate for a healthy adult ranges from 60 to 100 beats per minute, reports the University of Virginia Health System. The heart’s rhythm is controlled by electrical pulses produced in the natural pacemaker, known as the sinus node, located in the right atria (upper right chamber). When a condition, disease or outside stimulant interferes with the electrical system within the heart, the heart may respond by beating too fast. A heart rate that is significantly faster than normal is a condition known as tachycardia. Although some people who have a high heart rate experience no symptoms, others may feel dizziness, shortness of breath, lightheadedness or chest pain. A high heart rate interferes with the normal function of the heart, which can lead to dangerous effects.

Blood Clots

A rapid heart rate can cause the heart to pump ineffectively. This means that the contractions of the heart muscle are so fast that blood remains in the lower chambers, or the ventricles. As blood sits in the lower chambers of the heart, it can form clots. A blood clot within the heart can block blood flow, resulting in a heart attack. If the clot is pumped out of the heart, it can travel through the arteries of the body. A blood clot that becomes stuck in an artery leading to the brain deprives the brain of blood and, therefore, oxygen, resulting in a stroke.

Heart Failure

As the heart beats rapidly, less blood may be pumped to the body. In response, the heart tries to beat even faster to supply more blood and oxygen. Over time this causes greater and greater stress on the heart. When the heart is not able to pump blood as fast as the cells and organs in the body need it, heart failure can occur as described by the San Diego Cardiac Center sponsored website Heart Failure Online.

Frequent Fainting

A high heart rate can make the pumping action of the heart ineffective. When the tissues of the body are deprived of oxygen, the patient may feel dizzy and lightheaded. If the brain does not receive adequate oxygen, fainting--also called syncope--may occur. Frequent fainting can be a danger. It is a sign that the brain is being seriously deprived of oxygen, which can lead to further complications, including brain damage and stroke.

Sudden Death

There are several different types of tachycardia. Some originate in the atria, while others originate in the ventricles. In cases of ventricular tachycardia as well as in those of ventricular fibrillation, abnormal electrical impulses in the ventricles cause a high heart rate and interfere with the pumping of blood to the body. Both ventricular tachycardia and ventricular fibrillation are medical emergencies, according to doctors at the Mayo Clinic, as they can lead to sudden death if a normal heart rhythm is not restored.

What Makes a Heart Rate Fast?

Author

The American Heart Association reports that for the average, healthy adult, the heart beats about 60 to 80 times a minute when at rest. As you age, it’s not unusual for your heart rate to rise. People who are physically fit typically have a lower heart rate compared with those who do not exercise. Tachycardia is a heart rate that is faster than normal, and the causes can include excitement, high blood pressure, heart failure and more.

Heart Rate

The heart is a muscle that pumps oxygen-filled blood to all of your organs, cells and tissues. The right side of the heart receives blood from the body and pumps it to the lungs, according to Kids Health. The left side of the heart receives blood from the lungs and pumps it to the body. Prior to each heartbeat, the heart fills with blood, the muscle contracts and pushes the blood to its destination. While a normal resting heart rate is from 60 to 80 beats per minute, the Mayo Clinic indicates that a well-trained athlete will have a resting heart rate of 40 to 60 bpm. In a newborn baby, according to the National Institutes of Health, the heart can beat about 100 to 160 bpm. The resting heart rate of a teenager is generally about 60 to 100 bpm.

Medications

The Mayo Clinic warns that women who take 500 mg or more of acetaminophen daily are at risk for developing high blood pressure. Antidepressants, including Effexor, Wellbutrin and Nardil, can change the body’s response to certain chemicals in the brain, while at the same time increasing your heart rate. Many birth control pills and birth control devices contain hormones that can increase blood pressure by narrowing blood vessels. Using a birth control method containing a lower dose of estrogen could reduce your chances of spiking your blood pressure. Decongestants, including Sudafed and Afrin, also narrow blood vessels. The Mayo Clinic reports that some decongestant cold, flu and allergy medications may reduce the effect of certain blood pressure medications.

Tachycardia

Tachycardia is characterized by a significantly faster than normal heart rate. According to the NIH, tachycardias may cause no symptoms or complications. An abnormally fast heartbeat, however, can cause sudden cardiac arrest or stroke.
Tachycardia is caused when the normal electrical impulses in the heart are disrupted. This can occur if there is damage to the heart tissue from a heart attack, birth defect or abnormality of the heart, smoking, heavy alcohol or caffeine consumption, or an adverse reaction to illicit drugs or prescription medications.

Considerations

A fast heart rate is not always a bad thing. Exercise, excitement and just having a good time can set the heart in motion. When you exercise, your brain and organs need more oxygen, causing your heart to beat faster and pump more blood. In turn, when you’re not in motion, your resting heart rate is lower, and healthier, compared with those who don’t exercise.

In one casual experiment from a PBS program, kids measured their resting heart rates prior to and after riding a variety of roller coasters. Coasters that offered the least excitement increased the kids' heart rates by an average of 33.5 bpm. The scariest coaster increased their heart rates by an average of 54 bpm.

Reducing Your Heart Rate

For those whose heart rate runs high, it can’t hurt to take measures to lower it. Aerobic exercise, such as jogging, swimming or tennis, which raises your heart rate while you’re active, actually lowers your heart rate when you’re not exercising. Obesity can cause high blood pressure and cause your heart to race. By dropping pounds, you can eliminate the problem. The website Science Daily reports that relaxation techniques, such deep breathing, meditation and visualization, can reduce the heart rate and increase blood flow to major muscles.
