Heart Disease and Abnormal Heart Rhythm (Arrhythmia) An irregular heartbeat is an arrhythmia (also called dysrhythmia). Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together. Arrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias -- less than 50 beats per minute).

Arrhythmias Arrhythmias are deviations from the normal cadence of the heartbeat, which cause the heart to pump improperly. The normal heartbeat starts in the right atrium, where the heart's natural pacemaker (the sinus node) sends an electrical signal to the center of the heart to the atrioventricular node.rrhythmias occur when the heartbeat starts in a part of the heart other than the sinus node, an abnormal rate or rhythm develops in the sinus node, or a heart conduction block prevents the electrical signal from traveling down the normal pathway.

Dysrhythmia Some of these changes are normal—like Annie's palpitations * —while others are more serious. People's hearts naturally speed up with emotion or exercise and slow down during sleep. Other dysrhythmias are associated with heart disease and can be life threatening.

Arrhythmias What You Need to Know About Arrhythmias. Normally, special heart cells generate an electrical signal that travels through the heart. The electricity causes the heart muscle to contract, and that’s what makes a heartbeat. An arrhythmia means the heart is not beating in the proper rhythm.This can cause anything from minor symptoms all the way to cardiac arrest and death. Since different rhythm disturbances need different treatments, diagnosing the precise type of arrhythmia is important.ometimes arrhythmias are silent, meaning they cause no obvious symptoms. A doctor can detect an irregular heartbeat during a physical exam by taking your pulse, listening to your heart or by performing diagnostic tests.

- Arrhythmia refers to any kind of abnormal heart rhythm. There are two types of arrhythmias: atrial arrhythmia, also called supraventricular arrhythmia, which begins in the upper chambers of the heart, and ventricular arrhythmia, which begins in the lower chambers of the heart.

Arrhythmogenic Right Ventricular Dysplasia Arrhythmogenic right ventricular dysplasia (ARVD) is a rare type of cardiomyopathy. ARVD occurs if the muscle tissue in the right ventricle dies and is replaced with scar tissue. This process disrupts the heart's electrical signals and causes arrhythmias.

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) Arrhythmogenic right ventricular cardiomyopathy (ARVC; also known as arrhythmogenic right ventricular dysplasia – (ARVD)) is a heart muscle disease that can cause life-threatening heart rhythm abnormalities and, rarely, significant “weakening” of the right side of the heart.rrhythmogenic right ventricular cardiomyopathy (ARVC; also known as arrhythmogenic right ventricular dysplasia – (ARVD)) is a heart muscle disease that can cause life-threatening heart rhythm abnormalities and, rarely, significant “weakening” of the right side of the heart.

Arrhythmias (Heart Rhythm Disorders) Heart Rhythm Disorders Definition and Overview. A heart rhythm disorder is an abnormal variation from the normal heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following: heart rate, regularity of beats, sites where electrical impulses originate, or sequence of activation of heartbeats.Heart rhythm disorder is also referred to as an arrhythmia.The primary function of the heart is to supply blood and nutrients to the body. The regular beating, or contraction, of the heart moves the blood throughout the body. Each heartbeat is controlled by electrical impulses traveling through the heart.he irregular beating results in a heart rhythm disorder, or arrhythmia. The electrical system regulating heartbeat consists of two main areas of control that are connected to a series of conducting pathways, similar to the electrical wiring in a house. 1  The sinoatrial, or SA, node is located in the right atrium.

Difference Between Arrhythmia and Dysrhythmia Difference Between Arrhythmia and Dysrhythmia. Both arrhythmia and dysrhythmia mean the same. Arrhythmia means no regular rhythm and dysrhythmia means abnormal rhythm. Disturbances of cardiac rhythm or arrhythmias are common in people, often benign, and often intermittent. However, they can be severe sometimes leading to cardiac compromise.

Heart arrhythmia Sudden arrhythmic death syndrome (SADS), is a term used as part of sudden unexpected death syndrome to describe sudden death due to cardiac arrest brought on by an arrhythmia in the presence or absence of any structural heart disease on autopsy.

Abnormal heart rhythms Abnormal heart rhythms. An abnormal heart rhythm – sometimes called an arrhythmia – means your heart is beating too fast, too slow, or with an irregular pattern. Your heart has an electrical system that tells it when to beat and push blood around the body.

About Arrhythmia An arrhythmia is an abnormal heart rhythm. It may feel like fluttering or a brief pause. It may be so brief that it doesn’t change your. overall heart rate (the number of times per. minute that your heart beats). Or it can cause. the heart rate to be too slow or too fast. Some.

- Any type of abnormal heart rate or rhythm is termed an arrhythmia. Tachycardia is a type of arrhythmia where the electrical signals controlling the heart travel across the heart faster than normal, triggering the heart to beat too rapidly.

Heart Disease and Abnormal Heart Rhythm (Arrhythmia) An irregular heartbeat is an arrhythmia (also called dysrhythmia). Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together.

Arrhythmias A pacemaker is a small device that's placed under the skin of your chest or abdomen to help control abnormal heart rhythms. Pacemakers have sensors that detect the heart's electrical activity. When the device senses an abnormal heart rhythm, it sends electrical pulses to prompt the heart to beat at a normal rate. Some arrhythmias are treated with a jolt of electricity to the heart. This type of treatment is called cardioversion or defibrillation, depending on which type of arrhythmia is being treated.

Heart Diseases & Disorders Heart Diseases & Disorders. Millions of people experience irregular heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart disease. However, some abnormal heart rhythms can be serious or even deadly.lectrical: Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates the steady heartbeat. The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular and disorganized).

Overview By Mayo Clinic Staff. Print. Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly. Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless.

Tachycardia [edit on Wikidata] Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart). 1 Definition.

Cardiac Arrhythmias Some common types of cardiac arrhythmias include: Sinus node dysfunction - This usually causes a slow heart rate (bradycardia), with a heart rate of 50 beats per minute or less. The most common cause is scar tissue that develops and eventually replaces the sinus node. Why this happens is not known.
