从87例急性下壁心肌梗塞中选出有右室梗塞病人41例。41例病人根据是否合并完全性房室阻滞分成两组:15例有完全性房室阻滞(组Ⅰ)、26例无完全性房室阻滞(组Ⅱ)。诊断标准:1.急性心肌梗塞:符合WHO标准。2.右室梗塞:①在下壁导联有典型改变病人的右胸导联V_(3R)、V_(4R)有ST段抬高≥0.1mV;②其中15例有Swan-Ganz导管监测资料:右房平均压>1.33kPa及/或右房压/肺毛细血管楔压>0.65。3.Killip>Ⅱ级为急性左心衰竭。统计学处理采用t检验、x~2检验。两组病人各因素比较见附表。讨论急性下壁心肌梗塞合并完全性房室阻滞病人住院病死率文献报道不一(19～45％)。Mavric
From 87 cases of acute inferior myocardial infarction in 41 patients with right ventricular infarction. Forty-one patients were divided into two groups according to whether they had complete atrioventricular block or not: 15 patients had complete AV block (group Ⅰ), and 26 patients had incomplete AV block (group Ⅱ). Diagnostic criteria: 1. Acute myocardial infarction: in line with WHO standards. 2. Right ventricular infarction: (1) V_ (3R) and V_ (4R) of the right chest lead in the inferior leads with ST-segment elevation ≥0.1mV; (2) Swan-Ganz catheter monitoring data were obtained in 15 of them: Right atrial mean pressure> 1.33 kPa and / or right atrial pressure / pulmonary capillary wedge pressure> 0.65.3. Killip> Grade II acute left heart failure. Statistical analysis using t test, x ~ 2 test. The two groups of patients compare the various factors in the table. The in-hospital mortality of patients with acute inferior myocardial infarction complicated with complete atrioventricular block was reported in different reports (19 ~ 45%). Mavric
