paroxysmal atrial tachycardia Atrial tachycardia means that the upper chambers of the heart are beating abnormally fast. Paroxysmal atrial tachycardia can occur without any heart disease being present. It is usually more annoying than dangerous.

Atrial fibrillation Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating. Often it starts as brief periods of abnormal beating which become longer and possibly constant over time. Most episodes have no symptoms. Occasionally there may be heart palpitations, fainting, shortness of breath, or chest pain. The disease is associated with an increased risk of heart failure, dementia, and stroke. It is a type of supraventricular tachycardia. Hypertension and valvular heart disease are the most common alterable risk factors for AF.

Supraventricular Tachycardia (SVT) Supraventricular tachycardia is a series of rapid heartbeats that begin in or involve the upper chambers (atria) of the heart. SVT can cause the heart to beat very rapidly or erratically. As a result, the heart may beat inefficiently, and the body may receive an inadequate blood supply.

Atrial flutter Atrial flutter (AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia.

Heart arrhythmias and palpitations Ventricular tachycardia is a fast heart rhythm that starts in the lower part of the heart (ventricles). If left untreated, some forms of ventricular tachycardia may get worse and lead to ventricular fibrillation, which can be life-threatening. Ventricular tachycardia is a fast but regular rhythm. It can lead to ventricular fibrillation, which is fast and irregular. With ventricular fibrillation, the heartbeats are so fast and irregular that the heart stops pumping blood. Ventricular fibrillation is a leading cause of sudden cardiac death.

Learn how UpToDate can help you. Atrioventricular nodal reentrant tachycardia (AVNRT) is a regular supraventricular tachycardia (SVT) that results from the formation of a reentry circuit confined to the AV node and perinodal atrial tissue. Because of its abrupt onset and termination, AVNRT is categorized as a paroxysmal SVT (PSVT).

Atrial Flutter Atrial flutter is a common tachycardia (fast heart beat) that results from a rapid electrical circuit in the atrium (Figure 2). Atrial flutter can be caused by scarring in the heart resulting from prior cardiac disease or heart surgery, but it can also occur in some patients with no other identifiable heart problems.

- Ventricular tachycardia (V-tach, often abbreviated VT) refers to a rhythm that arises from the ventricles causing the heart to beat at a rate faster than 100 beats per minute. The ventricular rate is usually above 120 beats/min and may exceed 250 beats/min.

- From Wikipedia, the free encyclopedia. Atrial flutter (AFL) is an abnormal heart rhythm that occurs in the atria of the heart. When it first occurs, it is usually associated with a fast heart rate or tachycardia (beats over 100 per minute), and falls into the category of supra-ventricular tachycardias.rom Wikipedia, the free encyclopedia.

Atrial Fibrillation and Flutter Atrial Fibrillation and Flutter. Definition. Atrial fibrillation and flutter are abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart. In atrial fibrillation, the atria quiver chaotically and the ventricles beat irregularly.

Atrial Fibrillation (AFib) Atrial fibrillation (also referred to as AFib, Afib, A-fib, and AF) is an irregular and often rapid heart rhythm. The irregular rhythm, or arrhythmia, results from abnormal electrical impulses in the upper chambers (atria, singular=atrium) of the heart that cause the heartbeat (ventricle contraction) to be irregular and usually fast.

Atrial tachycardia Atrial tachycardia. Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.

- 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 or abnormal.

Atrial Tachycardia The primary treatment during a bout of atrial tachycardia is considered to be rate control using AV nodal blocking agents (eg, beta-blockers, calcium channel blockers). Antiarrhythmic drugs can prevent recurrences and may be required; a calcium channel blocker or beta-blocker also may be required in combination therapy.

Tachycardia | Fast Heart Rate Atrial or Supraventricular Tachycardia (SVT). Atrial or Supraventricular tachycardia (SVT) is a fast heart rate that starts in the upper chambers of the heart. Some forms are called paroxysmal atrial tachycardia (PAT) or paroxysmal supraventricular tachycardia (PSVT).entricular tachycardia is a fast heart rate that starts in the heart's lower chambers (ventricles). It can be a life-threatening heart rhythm and requires rapid diagnosis and treatment.

What is fertilization? Retired in 2005, breeding Araucana chickens. Fertilization is the act or process of initiating biological reproduction by insemination or pollination or the union of male and female reproductive cells (gametes) to produce a fertilized reproductive cell (zygote).
