室性心律临床常见,可以是因为窦性心动过缓时伴有逸搏现象,或室性心律绝对增高而形成室速;因其改变了心脏正常的激动顺序及激动不再沿室内传导通路传导,导致QRS波的形态异常及时限延长。这两种室性心律失常常见,临床同一患者同时存在室性逸搏心律、室速者较为少见,QRS波变化多端,易误诊误治。现报告1例如下。 Ventricular tachycardia is clinically common because ventricular tachycardia with sinus rhythm or absolute ventricular arrhythmia can cause ventricular tachycardia; it changes the normal activation of the heart and excites the conduction along the conduction path in the interior , Resulting in morphological abnormalities and prolonged QRS wave duration. These two kinds of ventricular arrhythmias are common, the clinical same patient with ventricular escape rhythm, ventricular tachycardia are rare, QRS wave changes, easy misdiagnosis and mistreatment. One report is as follows.
