For a variety of reasons, something - such as a structural heart defect - causes the heart to beat out of control. This abnormal heart rhythm is known as ventricular fibrillation.
在这多种原因中，一些会导致心跳失常，比如结构性心脏缺陷，这种异常的心律被称作。
2
Objective To study the relationship between multiple ventricular premature beat (MVPB) and myocarditis and the influence to cardiac function.
目的探讨频发室性早搏（MVPB）与心肌炎的关系及其对心功能的影响。

During proecedure main cardiac arrhythmia found its expression in node tachycardia beat(81.8% ), ventricular premature contraction (45.5% ) and after procedure in sinus rate variation.
