The heart normally beats between sixty and eighty times a minute. Arrhythmia is when the heart rate becomes abnormally rapid, slow and/or irregular. About arrhythmias Arrythmias are very common and may occur naturally, or be due to heart disease or other causes, such as a reaction to a drug. Arrhythmia may occur continuously or just occasionally. The heartbeat For general information on the heart, please see the BUPA factsheet The cardiovascular system A heartbeat starts as a small electrical impulse in a special part of the heart wall called at the sinoatrial node (SAN). This is sometimes called the heart's natural "pacemaker". A network of nerves conduct this impulse all over the heart, and in turn this causes contraction of the atria (the two smaller chambers) and ventricles (the two larger chambers). Each heartbeat is represented on a heart trace (electrocardiogram or ECG; see illustration below). ECG traces The symptoms of arrhythmia Many arrhythmias cause no symptoms and may go unnoticed. However they may lead to palpitations, which is an unpleasant awareness of the heartbeat, often described as a thumping in the chest. However, occasionally, arrhythmia can cause sudden death. Other symptoms may include:

47. When Heartbeats Go Haywire: New Treatments Can Save Lives An Indepth discussion on ventricular arrhythmias and new drugs and devices in curbing deaths from this disorder. http://www.fda.gov/fdac/features/1997/397_hart.html

When Heartbeats Go Haywire: New Treatments Can Save Lives by Margie Patlak Two-time Olympic gold-medalist skater Sergei Grinkov shocked the world in fall 1995, when he collapsed on the ice rink and died hours later at the young age of 28. A blood clot that blocked blood flow to his heart triggered it to quiver instead of beat. Medical technicians were unable to restore a normal heart rhythm, and by the time he reached a hospital, Grinkov's heart had stopped beating altogether. Grinkov suffered what is known as ventricular fibrillation. This inefficient and deadly quivering of the heart is one of several types of irregular heartbeats, or arrhythmias, that afflict the lower chambers, called the ventricles, of the heart. Not all arrhythmias are ventricular; some, for example, arise from the upper chambers of the heart. Ventricular arrhythmias often occur in people with various forms of heart disease and, according to the American Heart Association, cause most cases of sudden cardiac death. But new drugs and devices show promise in curbing the number of deaths from this condition. These new treatments, approved by the Food and Drug Administration, include a longer-acting form of an antiarrhythmia drug, a wide availability of portable and implantable electrical devices that can spark a return to normal heart rhythm, and techniques for destroying heart tissue that triggers ventricular arrhythmias. Heart of the Matter Not much bigger than a fist, the human heart beats 100,000 times each day, sending about 2,000 gallons of blood coursing through vessels, which, laid end-to-end, would be long enough to circle the earth more than twice.

HealingWithNutrition.com Home SiteMap Education Products Arrhythmia Arrhythmia is an abnormal rhythm or rate of heart beat and is caused by a disturbance in the electrical nerve impulses of the heart. Tachycardia is where the rate is faster than 100 beats per minute, and bradycardias is where the rate is slower than 60 beats per minute. In atrial flutter, the beat rate is 200 to 400 bests per minute, but not every impulse reaches the ventricles. A totally uncoordinated beating of the heart at about 300 to 500 beats per minute is called atrial fibrillation. The most common cause of arrhythmia is arteriosclerosis where deposits narrow the blood vessels and inadequate blood supply reaches the heart muscle. Arrhythmias occur more frequently after a heart attack. Caffeine and other drugs can also cause tachycardia. and Certain antidepressant drugs can cause serious cardiac arrhythmias if taken in high doses.

NCRR MIT-BIH Arrhythmia Database Since 1975, our laboratories at Boston's Beth Israel Hospital (now the Beth Israel Deaconess Medical Center) and at MIT have supported our own research into arrhythmia analysis and related subjects. One of the first major products of that effort was the MIT-BIH Arrhythmia Database, which we completed and began distributing in 1980. The database was the first generally available set of standard test material for evaluation of arrhythmia detectors, and has been used for that purpose as well as for basic research into cardiac dynamics at more than 500 sites worldwide. Originally, we distributed the database on 9-track half-inch digital tape at 800 and 1600 bpi, and on quarter-inch IRIG-format FM analog tape. In August, 1989, we produced a CD-ROM version of the database; since that time, we have supplied it on CD-ROM only. The MIT-BIH Arrhythmia Database contains 48 half-hour excerpts of two-channel ambulatory ECG recordings, obtained from 47 subjects studied by the BIH Arrhythmia Laboratory between 1975 and 1979. Twenty-three recordings were chosen at random from a set of 4000 24-hour ambulatory ECG recordings collected from a mixed population of inpatients (about 60%) and outpatients (about 40%) at Boston's Beth Israel Hospital; the remaining 25 recordings were selected from the same set to include less common but clinically significant arrhythmias that would not be well-represented in a small random sample.

Each perceived thump of the heart actually consists of two beats, one by the upper chambers, or atria, and one by the lower chambers, or ventricles. The contractions are triggered by electrical impulses originating in the sinoatrial node, a specialized group of cells located in the heart's right atrium. More In-Depth Info: Heart Center Any disturbance in the normal beating pattern of the heart is called an arrhythmia, or irregular heartbeat. Practically everyone experiences some version of an arrhythmia on occasion, usually in the form of a mild palpitation or a "skipped" heartbeat. (In fact, what feels like a skipped beat is really an early beat, weak enough not to be felt, then a one- or two-second pause, followed by a relatively forceful beat; the delay between beats feels like a skip.) Mild, isolated disturbances of this sort are normally harmless. A recurrent arrhythmia, on the other hand, should be checked by a physician.

Cardiac arrhythmia From Wikipedia, the free encyclopedia. Cardiac arrhythmia is a group of conditions in which muscle contraction of the heart is irregular for any reason. Cardiac dysrhythmia is technically more correct, as arrhythmia would imply the rhythm is completely unpredictable, but this term is not used frequently. Several arrhythmias are life-threatening events and medical emergencies , while others are harmless. Contents Frequency too high/low Fibrillation Origin of impulse Automaticity ... edit Frequency too high/low A rhythm of the heart at a rate of more than 100 beats/minute is considered a tachycardia . If the ventricles of the heart experience tachycardia for a sustained period of time, there can be deleterious effects. Individuals may sense a tachycardia as a pounding sensation of the heart, known as palpitation . However, strictly speaking, palpitations are any sensation of an individual's own heart beat, and can occur at rates less than 100 beats/minute. The causes of tachycardias are numerous, and include stress, ingested or injected substances (ie:

Coronary artery disease accounts for the majority of cases, while most of the others are associated with anatomic abnormalities and are presaged by clinical signs and symptoms (Table 1) . Occasionally, the underlying heart disease remains undiagnosed, and death comes suddenly and unexpectedly, but the postmortem examination reveals a cause. In 1 to 5 percent of deaths, however, no anatomic abnormality can be found, and this group constitutes the newly described "sudden arrhythmia death syndrome" (SADS).

Arrhythmia: A Patient Guide An arrhythmia is any type of irregular heartbeat. It may present itself as a skipped beat, a rapid or slow heart rate, or a continuous irregular heartbeat. Each year, millions of people are affected by arrhythmias, most of which can be treated and are not life-threatening. However, many arrhythmias can be very dangerous and contribute to approximately 500,000 deaths in the US each year. Early and appropriate diagnosis and treatment can help decrease the number of deaths from arrhythmias between 15 percent and 25 percent annually. How does the heart beat? The heart consists of four chambers, the right and left atria and the right and left ventricles. The heart beats, or contracts, because of electrical stimulation of heart muscle tissue. Electrical impulses originate in the sinus node (the heart's natural pacemaker), which is a group of special cells located in the high right atrium. The sinus node, in turn, sends the electrical signal throughout both atria to the atrioventricular (A-V) node. The A-V node transmits the signal to a group of fibers throughout the ventricles (see accompanying animation NOTE: requires Macromedia Flash Player) . Stimulation of muscle in the ventricle is ultimately what causes the familiar sensation of a heartbeat. A normal heart rate for an adult is between 60 beats and 100 beats per minute. In order for the heart to beat properly, the signal must follow an exact course throughout the heart.
