一、室性心动过速的分型及诊断 (一)阵发性室性心动过速本型是最常见的临床类型,常移行于室性早搏之后,即由阵发的一连串室性早搏所组成,其QRS-T波形态与发作前后的室性早搏波形一致,因此,又称为“室性早搏型心动过速”。室性频率多在160～220次/min之间,也可见到未下传的窦性P波,由于窦性冲动慢不易下传,因此而产生房室分离。
First, the classification and diagnosis of ventricular tachycardia (A) paroxysmal ventricular tachycardia This type is the most common clinical type, often moving in the premature ventricular contractions, that is, a series of premature ventricular contractions by the Composition, QRS-T wave morphology before and after the onset of premature ventricular waveform consistent, therefore, also known as “ventricular premature beat tachycardia.” Ventricular frequency more than 160 ~ 220 times / min, but also can not see the sinus P wave is not transmitted, because sinus impulses slow down easily, resulting in atrio-ventricular septation.
