Welcome

Arrhythmia is an important category of health concerns, with 9 topics, including: Atrial Fibrillation, Heart Murmurs, Atrial Flutter, Atrial Premature Complexes, Ventricular Fibrillation, Premature Ventricular Co...

Atrial Fibrillation
Atrial fibrillation/flutter is a heart rhythm disorder (arrhythmia). It usually involves a rapid heart rate , in which the upper heart chambers (atria) are stimulated to contract in a very disorgan...
Heart Murmurs
Murmurs are blowing, whooshing, or rasping sounds produced by turbulent blood flow through the heart valves or near the heart.
Atrial Flutter
Atrial fibrillation/flutter is a heart rhythm disorder (arrhythmia). It usually involves a rapid heart rate , in which the upper heart chambers (atria) are stimulated to contract in a very disorgan...
Atrial Premature Complexes
Atrial ectopic beats (AEB) refers to a contraction of the upper heart chamber which occurs before it would be expected. Atrial ectopic beats are also known as premature atrial beats, premature atri...
Ventricular Fibrillation
Ventricular fibrillation (VF) is a severely abnormal heart rhythm ( arrhythmia ) that, unless treated immediately, causes death. VF is responsible for 75% to 85% of sudden deaths in persons with he...
Premature Ventricular Complexes (PVC)
A ventricular ectopic beat (VEB) is an extra heartbeat originating in the lower chamber of the heart. This beat, also called a premature ventricular contraction (PVC), occurs before the beat trigge...
Ventricular Tachycardia (VT)
Ventricular tachycardia is a rapid heart beat initiated within the ventricles, characterized by 3 or more consecutive premature ventricular beats.
Paroxysmal Supraventricular Tachycardia (PVST)
Paroxysmal supraventricular tachycardia (PSVT) is a rapid heart rate , which occurs from time to time (paroxysmal). PSVT starts with events taking place above the ventricles.
Multifocal Atrial Tachycardia
Multifocal atrial tachycardia describes a rapid heart rate caused by inappropriate electrical impulses arriving at the lower heart chambers (ventricles) from multiple locations within the upper hea...
