为探索右室梗塞的心电图改变和诊断标准,对5例患者采用CR_(3R)、CR_(5R)、CR_(7R)、V_(7R)和V_(8R)导联描记心电图,结果ST段抬高出现于发病后5—8小时,抬高幅度为0.15—0.3mV,持续8—15天,较V_(3R)-V_(6R)显著。另外尚出现具有诊断意义的坏死性Q波,而20例对照者无一出现Q或QS波。并就沿用的右室梗塞诊断标准作了评价,讨论双极、单极右胸导联的区别,提出急性左室前壁心肌梗塞合并右室梗塞的可能性。
In order to explore the electrocardiographic changes and diagnostic criteria of right ventricular infarction, ECG was performed on CR_ (3R), CR_ (5R), CR_ (7R), V_ (7R) and V_ (8R) High appeared in the 5-8 hours after onset, the elevation of 0.15-0.3mV, lasting 8-15 days, V_ (3R) -V_ (6R) significantly. In addition, there are still diagnostic significance of necrotic Q waves, while none of the 20 controls appeared Q or QS waves. The diagnostic criteria of right ventricular infarction used were evaluated. The differences between bipolar and unilateral right chest leads were discussed. The possibility of acute left ventricular anterior myocardial infarction combined with right ventricular infarction was proposed.
