由于心房心肌梗塞(AT)常与心室心肌梗塞(MI)相伴随,确诊较为困难;而右室心肌梗塞(RVMI)具有不同于左心室MI的血流动力学改变、早期并发症以及治疗和预后,故急性心肌梗塞(AMT)时,早期发现AI或RVMI,对于预防并发症和采取正确的治疗措施以提高疗效和改善预后均很重要。 1 心房心肌梗塞 1.1 临床特征第1例AI报道于1925年,是一位60岁充血性心力衰竭患者在尸检中发现;首例ECG提示、尔后得到尸检证实的AI见于1937年;首例根据体表ECG出现的心脏完全阻滞并PTa段变化而于死前作出诊断的AI是在1948年(Ta波代表心房T波或复极化;正常时Ta波隐藏在QRS波
Because atrial myocardial infarction (AT) often accompanied by ventricular myocardial infarction (MI), diagnosis is more difficult; and right ventricular myocardial infarction (RVMI) has a different from left ventricular MI hemodynamic changes, early complications and treatment and prognosis Therefore, the early detection of AI or RVMI during acute myocardial infarction (AMT) is important for preventing complications and taking the proper treatment to improve efficacy and improve prognosis. 1 atrial myocardial infarction 1.1 Clinical features The first case of AI reported in 1925, was a 60-year-old patients with congestive heart failure was found in the autopsy; the first ECG prompts, later confirmed by autopsy AI found in 1937; the first case based on body Table ECG appeared completely blocked the heart and changes in PTa segment before the death to make a diagnosis of AI is in 1948 (Ta wave represents atrial T wave or repolarization; normal Ta waves hidden in the QRS wave
