variation from the normal rhythm, especially of the heartbeat; see also dysrhythmia.
1. An irregularity in the force or rhythm of the heartbeat: a fatal arrhythmia. 2. A condition characterized by such irregularities: treatments for cardiac arrhythmia. [New Latin, from Greek arruthmiÄ, lack of rhythm, from arruthmos, unrhythmical : a-, without; see a-1 + rhuthmos, rhythm; see rhythm.]
Definition of benign versus malignant ventricular arrhythmias: targets for treatment.. Benign ventricular arrhythmias occur in patients without known heart disease and do not require treatment.
Abstract. Benign cardiac arrhythmias are those which cause neither symptoms nor haemodynamic upset and which have no prognostic significance. Such arrhythmias include sinus arrhythmia, isolated atrial ectopic beats and infrequent ventricular ectopic beats.
Arrhythmia is an abnormal heart rhythm created by a disturbance in the heart's electrical. On the other hand, some arrhythmias are common, so-called benign
Heart arrhythmia is a group of conditions in which the heartbeat is irregular, too fast, or too slow. . that initiates an impulse without waiting for the sinoatrial node is called an ectopic focus and is, by definition, a pathological phenomenon.
