急性心肌梗死伴有房性快速性心律失常的发生率、类型、病因、临床结局和病死率仍有争论。本文对917例经监护的急性心肌梗死病人的情况进行分析。其中有房性快速性心律失常者104例(占11％),包括房颤67例、房扑29例、阵发性房性心动过速33例。79例为单一的房性快速性心律失常,25例为复合的房性快速性心律失常,90％病人的心律失常出现于急性心肌梗死后4天内,50％病人在发生房性快速性心律失常前出现房性期前收缩。以往认为急性心肌梗死合并房性快速性心律失常的病因与充血性心力衰竭、心源性休克、窦房结动脉供血障碍和心包炎有关。但本文资料表明仅与心包炎
Acute myocardial infarction with atrial tachyarrhythmia incidence, type, etiology, clinical outcome and mortality is still controversial. This article analyzes the 917 cases of patients with acute myocardial infarction monitored. Among them, 104 cases (11%) had atrial tachyarrhythmia, including 67 cases of atrial fibrillation, 29 cases of atrial flutter and 33 cases of paroxysmal atrial tachycardia. 79 were single atrial tachyarrhythmia, 25 were complex atrial tachyarrhythmia, 90% of patients arrhythmia occurred within 4 days after acute myocardial infarction, 50% of patients in the occurrence of atrial tachyarrhythmia Before the emergence of atrial contraction. In the past that the cause of acute atrial infarction with atrial tachyarrhythmia and congestive heart failure, cardiogenic shock, sinus node blood supply disorders and pericarditis. However, this data shows that only with pericarditis
