从临床心电图及电生理试验业已观察到室性并行收缩伴传出阻滞。室性并行收缩性心动过速亦可伴有传出阻滞,如在并行收缩灶与心肌之闻产生2∶1或Ⅱ°二型传出沮滞并不少见,但合并文氏型传出阻滞则属罕见,可使并行收缩诊断带来困难,倘若同时合并有其它类型室性心律失常,致使并行收缩的诊断更为复杂化。本文报道1例罕见的室性并行收缩性心动过速伴文氏型阻滞和高度传出阻滞,同时合并室性折返性早搏及短串室性心动过速。
Ventricular parallel contraction with block-out has been observed from clinical electrocardiogram and electrophysiological tests. Ventricular tachycardia and tachycardia may also be associated with block, such as parallel contraction of the heart and heart muscle smell produced 2: 1 or Ⅱ ° type 2 out of the depression is not uncommon, but the merger of the Wen’s type Blocking is rare and can make it difficult to diagnose parallel contractions, complicating the diagnosis of concurrent contractions if other types of ventricular arrhythmias are combined. This article reports a rare case of ventricular tachycardia accompanied by Paroxysmal type of block and high-level block, combined with ventricular reentrant premature beats and short-tailed ventricular tachycardia.
