患者男性,71岁,因“再发下壁心肌梗塞伴急性左心衰竭”入院。入院后给予抗心衰治疗,3h后出现频发室早和短阵室速,给予利多卡因(500mg+500ml液体)静滴后,室速消失,仍有偶发室早。入院第3日出现并行收缩性室早(附图上行)。数min后血压开始下降至零,同时心电示波显示心室分离成不相关的2个节律点(附图中、下行):一个节律点为室扑,其频率150次/min左右,振幅基本一致,间距相等形态相同,另一节律点为缓慢的窦性心律,其频率23—29次/min,QRS0.12s.可见P波,P-R0.19s。二种心律互不相关。此种分离持续3min后心跳停止。
The patient, male, aged 71, was admitted for “recurrent inferior myocardial infarction with acute left heart failure.” After admission to give anti-heart failure treatment, 3h after the occurrence of frequent ventricular tachycardia and short-term ventricular tachycardia, given lidocaine (500mg + 500ml liquid) intravenous infusion, ventricular tachycardia disappeared, there are still occasional room early. Symptoms appear on the 3rd day of admission contractile room early (with the image above). Blood pressure began to decline to zero after a few minutes, while ECG showed ventricular separation into two unrelated rhythm points (the figure, the downlink): a ventricular beat ventricular flutter frequency 150 times / min, the basic amplitude Consistent with the same spacing, the same shape, the other rhythm point for the slow sinus rhythm, the frequency of 23-29 times / min, QRS0.12s. P wave can be seen, P-R0.19s. Two kinds of heart rhythm are irrelevant. This separation lasted 3min after the heartbeat stopped.
