The mortality one year after a myocardial infarction varies between 2 and 60% according to the subjects. Thus, there is a group of patients at high risk of sudden death which it is important to be able to define. These patients are characterised by a lesion of the left ventricle with a decrease in the ejection fraction to below 0.40 and the presence of disorders of ventricular excitability on the Holter recording. This examination is able to demonstrate the signs of severity of the extrasystoles by showing an elevated number of ventricular extrasystoles (VEB) (greater than 1%) and the appearance in pairs or in runs. 24 hour Holter monitoring may miss a complex arrhythmia and the increase in the duration of the monitor increase the sensitivity. However, it should be associated with an evaluation of the ejection fraction and possible with invasive investigations such as programmed ventricular stimulation in high risk patients.
心肌梗死后一年的死亡率因个体不同在2%至60%之间。因此，有一组猝死高危患者，能够明确界定这组患者很重要。这些患者的特征是左心室病变，射血分数降至0.40以下，且动态心电图记录显示存在心室兴奋性紊乱。这项检查能够通过显示室性期前收缩（VEB）数量增加（大于1%）以及成对或成串出现的情况来证明期前收缩的严重程度迹象。24小时动态心电图监测可能会漏诊复杂心律失常，延长监测时间可提高敏感性。然而，它应与射血分数评估相关联，对于高危患者可能还需结合侵入性检查，如程控心室刺激。
