Arrhythmia Treatment and Symptoms Arrhythmias; Atrial Fibrillation; Irregular Heartbeat; Tachycardia
A cardiac arrhythmia, also called cardiac dysrhythmia, is a disturbance in the regular rhythm of the heartbeat. Several forms of cardiac arrhythmia are life-threatening and a medical emergency. A rhythm of the heart at a rate of more than 100 beats/minute is considered a tachycardia.A more serious variety of arrhythmia is known as fibrillation. Fibrillation occurs when the heart muscle begins a quivering motion instead of a normal, healthy pumping rhythm. Atrial fibrillation is the quivering, chaotic motion in the upper chambers of the heart, known as the atria. Atrial fibrillation is often due to serious underlying medical conditions, and should be evaluated by a physician. It is not typically a medical emergency. If fibrillation occurs in the ventricles (lower chambers) of the heart, it is always a medical emergency. If left untreated, ventricular fibrillation can lead to death within minutes.
