在各种危险的心律失常中,阵发性室性心动过速和心室纤颤是危及生命的重要的心律失常。心室纤颤能使心室肌失掉一致性收缩功能,并能使心室的泵功能完全消失而致死亡。室性心动过速因心率数持续时间不同其病态各异,室性心动过速本身或转为心室纤颤均可致死。因此,这些致死性心律失常的诊断治疗是极为重要的。用普通标准12导联心电图和动态心电图,虽可检出室性早搏和阵发性室性心动过速,但很难预测可突然致死的持续型室性心动过速和心室纤颤等心律失常的发生,因而多在症状出
Paroxysmal ventricular tachycardia and ventricular fibrillation are important life-threatening arrhythmias in a variety of dangerous arrhythmias. Ventricular fibrillation can make the ventricular muscle loss of consistent systolic function, and can make the ventricular pump function disappeared completely and cause death. Ventricular tachycardia due to different duration of heart rate vary in their pathologies, ventricular tachycardia itself or converted to ventricular fibrillation can be fatal. Therefore, the diagnosis and treatment of these lethal arrhythmias is extremely important. With the standard 12-lead ECG and Holter, premature ventricular contractions and paroxysmal ventricular tachycardia can be detected, but it is difficult to predict arrhythmias such as persistent ventricular tachycardia and ventricular fibrillation that may suddenly lead to death The occurrence of more symptoms
