某些Ⅱ°或Ⅲ°房室传导阻滞或室性早搏病人,其夹有QRS波的P-P间期较无心室搏动的P-P间期为短,相差0.02秒以上,该现象称为室相性窦性心律不齐。最近我们遇到1例急性膈面与后壁心肌梗塞合并高度房室传导阻滞病人,其室相性窦性心律不齐与一般文献所描述的相反,即夹有QRS波的P-P间期较无心室搏动的P-P间期为长(附图)。附图为模拟V5导联记录。梯形图示P波
Some Ⅱ ° or Ⅲ ° atrioventricular block or premature ventricular contractions in patients with PPS interventricular septal QRS wave than the non-ventricular beating PP interval is short, a difference of 0.02 seconds or more, the phenomenon known as ventricular sinus Arrhythmia. Recently, we encountered a case of acute diaphragmatic and posterior wall myocardial infarction with atrioventricular block in patients with sinus ventricular arrhythmia and literature generally described the opposite, that is, with PPS interventricular septal QRS wave without heart Room pulsatile PP interval is long (with photos). The figure is simulated V5 lead record. Ladder shows P wave
