According to MayoClinic.com, 40 percent of deaths are related to heart disease each year in the United States. Heart rate monitors are simple, inexpensive tools that may catch life-threatening arrythmias, or malfunctions in heart rhythm. Dependent...
If you have ever experienced heart palpitations or shortness of breath, you've likely considered the possibilities of these symptoms. If you visited a doctor concerning these symptoms, he likely performed an in-office EKG, or electrocardiogram. In...
An arrhythmia is an abnormal heart rhythm. This includes a pulse that is too fast, too slow or skips beats. Sometimes arrhythmias are harmless and may only occur periodically. In other cases, they can be a sign of an underlying disease. In order...
Being able to identify common symptoms of mitral valve stenosis allows you to diagnose this potentially serious heart condition and begin to undergo treatment. People who have mitral stenosis have a narrowing in the mitral valve, which prevents...
A Holter monitor records heart rhythm the same way an electrocardiogram does in a hospital. Holter devices work at home to provide doctors with the details of your heart function as you go about your daily activities. Tests of this nature provide...
Aerobic exercise requires the heart, lungs and skeletal muscles to work hard in order to build strength and endurance. During exercise, most people experience an increased heart rate, increased breathing rate and muscle soreness. Pain or...
Educate yourself about the physical symptoms that may accompany atrial fibrillation. Not everyone who has this type of rapid, irregular heartbeat shows outward symptoms of the disorder. People who do feel something abnormal going on with their...
Anxiety is a ubiquitous experience. When severe, it can indicate a psychiatric problem. Various medical conditions can cause anxiety. Before concluding that anxiety stems from psychological problems, a physician should assess the patient to rule...
Cardiac ischemia, also referred to as myocardial ischemia, occurs when the oxygen supply in your heart is reduced due to a partial or complete blockage of an artery that pumps blood to your heart. This causes your heart to become weak and damaged...
Atrial fibrillation is the most common type of irregular heartbeat, or arrhythmia, and it currently affects 2.2 million Americans, according to the American Heart Association. The irregular, rapid heart rate associated with atrial fibrillation...
Atril fibrillation, or a fib, is the most common irregular heart rhythm. It can be related to heart disease, stress, excessive caffeine or alcohol use or electrolyte imbalances. When the heart is in a fib, it is not beating efficiently and is...
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare condition, but one of the most common causes of sudden unexpected death in athletes. In this progressive disorder, fibrous scar tissue and fat replace normal muscle cells of the...
According to the American Academy of Family Physicians and the American College of Physicians, atrial fibrillation is the most common form of arrhythmia, or abnormal heart rate, in adults. Furthermore, according to the Centers for Disease Control...
A racing heart, while frightening, is not usually a sign of a serious or harmful condition, according to the National Heart Lung and Blood Institute. Heart palpitations, or a fast heartbeat, may be caused by stress, certain medical conditions or...
People with cardiac arrhythmia experience an irregular heartbeat. Irregular heartbeats are caused by illnesses, electrolyte imbalances and sometimes by unknown factors. Some arrhythmias linger silently for years, causing no problems or symptoms....
Low pulse rates, or bradycardia, can be caused by multiple conditions in children. Normally, electrical signal in the heart control the rate of contraction. Disruption of these pathways can cause a low pulse rate. Recognition of the signs and...
An electrocardiogram, also referred to as an ECG or EKG, is a recording of the electrical current in the heart. An electrocardiograph produces a strip graph of the recorded electrical activity and provides results for the doctor to determine...
The heart is an amazing organ, beating an average of 100,000 times per day to pump blood throughout the body. The precise timing and contraction of the heart is mainly due to an electrical pathway starting from the top chambers of the heart...
A normal heart beats at a rate from 60 to 100 times a minute, according to the Heart Rhythm Society website. Your heart rate can increase to 160 to 180 or more beats per minute during intense exercise. Variations in diet, medication, activity and...
Your heart's conduction system creates a steady heartbeat that increases in response to exercise. The physiological changes of the heart during exercise are reflected in EKG tracings. The electrical activity of your heart recorded by the EKG...
Tachycardia is defined as a faster than normal heart rate; normal being between 60 to 100 beats per minute in a healthy adult at rest. The heart is made up of four chambers, two atria at the top and two ventricles at the bottom. The rhythm of the...
