摘要：

Identification of the QRS-complex duration in acute myocardial infarction (MI) is of great importance, having diagnostic, therapeutic and prognostic consequences. In acute MI with ST-segment deviation, the terminal part of QRS complex is distorted, without a clear demarcation between QRS and ST segment, making the identification of the QRS-complex offset problematic. Almer et al. [2016] propose a method that shifts the offset of the QRS complex deep into the ST segment. This method is in agreement with computer simulations showing the overlapping of depolarization and repolarization, as a possible additional factor resulting in the ST-segment deviation.
