Cardiac Arrhythmias A cardiac arrhythmia is any abnormal heart rate or rhythm. In normal adults, the heart beats regularly at a rate of 60 to 100 times per minute. And the pulse (felt at the wrist, neck or elsewhere) matches the contractions of the heart's two powerful lower chambers, called the ventricles.

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. If there is a problem with this system you may experience an abnormal heart rhythm.

Arrhythmia Arrhythmia is an electrical problem that disrupts the heart's natural rhythm. It manifests in two types Tachycardia (Fast heart beat-over 130 beats per minute)and Bradycardia (Slow heart beat-under 60 beats per minute).

Overview A heart arrhythmia is an abnormal heartbeat. Your heart may beat too quickly, too slowly or irregularly. Heart arrhythmia symptoms can include: 1  Fluttering in your chest. 2  Racing heartbeat (tachycardia). 3  Slow heartbeat (bradycardia). 4  Chest pain or discomfort. 5  Shortness of breath. 6  Lightheadedness.

Arrhythmias URL of this page: //medlineplus.gov/ency/article/001101.htm. An arrhythmia is a disorder of the heart rate (pulse) or heart rhythm. The heart can beat too fast (tachycardia), too slow (bradycardia), or irregularly. Normally, your heart works as a pump that brings blood to the lungs and the rest of the body.

- Atrial flutter is an abnormality in the beating of the heart. Such abnormalities, whether in the rhythm or speed of the heartbeat, are known as arrhythmias. The heart is a muscle that pumps the blood through the body.

Sinus Arrhythmia Sinus arrhythmia is a normal physiological phenomenon, most commnonly seen in young, healthy people. The heart rate varies due to reflex changes in vagal tone during the different stages of the respiratory cycle. Inspiration increases the heart rate by decreasing vagal tone.

Arrhythmia The SA node is a group of cells located at the top of your heart's upper right chamber (the right atrium). Any irregularity in your heart's natural rhythm is called an arrhythmia. Almost everyone's heart skips or flutters at one time or another, and these mild, one-time palpitations are harmless.

Cardiac Arrhythmia or Cardiac Dysrhythmia An arrhythmia (also known as dysrhythmia) is any disorder of the heart rate or heart rhythm, such as beating too fast (tachycardia), too slow (bradycardia), or irregularly . Some arrhythmias are life-threatening medical emergencies that can result in cardiac arrest and sudden death.

Heart arrhythmia Cardiac arrhythmia. Cardiac arrhythmia, also known as cardiac dysrhythmia or irregular heartbeat, is a group of conditions in which the heartbeat is irregular, too fast, or too slow. A heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia and a heart rate that is too slow – below 60 beats per minute – is called bradycardia.

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 can also occur with rapid heart rates (called tachyarrhythmias -- faster than 100 beats per minute).

Arrhythmia Arrhythmias are further defined by the speed of the heartbeats. A very slow heart rate, called bradycardia, means the heart rate is less than 60 beats per minute. Tachycardia is a very fast heart rate, meaning the heart beats faster than 100 beats per minute.

Heart arrhythmia Antiarrhythmic agents are pharmaceuticals used to combat cardiac arrhythmias. An arrhythmia is an abnormality of the rate or rhythm of the heartbeat, such as atrial fibrillation, atrial flutter, ventricular fibrillation and ventricular tachycardia.

- Arrhythmia—a cardiac disease in which the heart beats irregularly or at an abnormal pace—is caused by faulty electrical signal generation within the heart at the SA node. Recognizing the electrical properties of the heart, engineers created a treatment device, the artificial pacemaker, by applying principles of electrical engineering. The device controls the rate and rhythm of the heartbeat by overriding faulty natural signals with generated electrical pulses.

Arrhythmias (Heart Rhythm Disorders) What are other types of arrhythmias (heart rhythm disorders)? Bradyarrhythmias produce heart rates that are too slow to allow enough blood to be pumped during either time of demand (stress or increased activity) or even during normal activity. Bradyarrhythmias are usually slower than 60 beats per minute.

What Is Atrial Fibrillation? Home | What is Atrial Fibrillation? Atrial fibrillation, often referred to as afib, is an irregular heartbeat, a rapid heartbeat, or a quivering of the upper chambers of the heart, called the atria. Atrial fibrillation is due to a malfunction in the heart's electrical system, and is the most common heart irregularity, or cardiac arrhythmia.

About Arrhythmia Electrocardiography (ECG or EKG) is a painless, non-invasive procedure that records the heart’s electrical activity and can help diagnose arrhythmias. Arrhythmias are abnormal beats. The term arrhythmia refers to any change from the normal sequence of electrical impulses, causing abnormal heart rhythms.

- Atrial tachycardia is a type of atrial arrhythmia in which the heart 's electrical impulse comes from ectopic atrial pacemaker, that is to say an abnormal site in the upper chambers of the heart or atria, rather than from the SA node which is the normal site of origin of the heart's electrical activity.trial tachycardia is a type of atrial arrhythmia in which the heart 's electrical impulse comes from ectopic atrial pacemaker, that is to say an abnormal site in the upper chambers of the heart or atria, rather than from the SA node which is the normal site of origin of the heart's electrical activity.

Cardiac Arrhythmia or Cardiac Dysrhythmia Common Cardiac Arrhythmias. • Supraventricular tachycardia - a fast heart rate that originates in the upper chambers of the heart (atria). The most common are atrial fibrillation or flutter, and atrioventricular nodal reentry tachycardia. • Ventricular tachycardia - a fast heart rate that originates in the lower chambers of the heart (ventricles).

Atrial Fibrillation What Is Atrial Fibrillation? Atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is the most common type of arrhythmia (ah-RITH-me-ah). An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. AF occurs if rapid, disorganized electrical signals cause the heart's two upper chambers—called the atria (AY-tree-uh)—to fibrillate.

Abnormal heart rhythms An abnormal heart rhythm – also 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 pump blood around your body.

Atrial fibrillation - arrhythmia Atrial fibrillation - arrhythmia Atrial fibrillation is a type of abnormal heart rhythm of your heart. Atrial fibrillation starts in the upper chambers of your heart (the atria) and causes them to quiver (fibrillate), instead of beating normally. This can mean your heart doesn’t pump blood around your body as efficiently as it should.
