右心室心肌梗塞(简称RVI)临床较少见,以往认为生前较难诊断,多需经病理解剖确诊。其原因是:①RVI与左心室心肌梗塞(LVI)不同,常规心电图对其无定位特征;②右心室壁较左心室壁薄,电势弱,即使发生梗塞心电图也不易表现出来。近年来,随着Swan—Ganz导管,超声心动图及核医学等诊断技术的开展,为RVI的临床诊断提供了血液动力学参数和其他诊断指标,使其 Right ventricular myocardial infarction (referred to as RVI) clinical less common in the past that before diagnosis more difficult to diagnose by pathological anatomy. The reason is: ① RVI and left ventricular myocardial infarction (LVI) is different from the conventional ECG without its positioning characteristics; ② right ventricular wall than the left ventricular wall thin, weak potential, even if the occurrence of infarction ECG is not easy to show. In recent years, with the Swan-Ganz catheter, echocardiography and nuclear medicine and other diagnostic techniques for the clinical diagnosis of RVI provides hemodynamic parameters and other diagnostic indicators, making it
