经心电图证实为心肌梗死的128名患者,心搏徐缓(少于60次/分)显著多见于后壁心肌梗死(73病人中有32人),而前壁心肌梗死,则较少见心搏徐缓(55病人中只有7人)。窦性心搏徐缓者,预后良好。其他原因引起的心搏徐缓(诸如结性节律或心传导阻滞),则病死率高(21例中有9例,占42.9%)。因此,当发现脉搏异常徐缓时,应密切注意观察,并 128 patients confirmed by electrocardiogram as myocardial infarction were significantly more likely to have posterior myocardial infarction (32 of 73) with bradycardia (less than 60 beats / min), whereas less severe aspiration of the anterior wall myocardial infarction Xu slow (only 55 of 55 patients). Sinus bradycardia, the prognosis is good. Other causes of bradycardia (such as nodal rhythm or heart block), the case fatality rate (21 cases, 9 cases, accounting for 42.9%). Therefore, when the abnormal pulse is slow, should pay close attention to observation, and
