Is electrocardiography alone enough to evaluate the right ventricular involvement to predict short-term outcome?

We read the article entitled ‘‘Short-term outcome of acute inferior wall myocardial infarction (IWMI) with emphasis on conduction blocks: a prospective observational study in Indian population’’ by Kumar et al. (1) published in Anatol J Cardiol 2017; 17: 229-34 with great interest. In this study, the authors have reported that the mortality rate was higher in patients with conduction blocks than in subjects without conduction blocks. According to the study, subjects with IWMI were not enrolled homogenously since some subjects did not receive reperfusion therapy, including thrombolytic therapy and in some subjects, coronary angiography was not performed at follow-up. The rate of thrombolytic therapy in the group with conduction block was statistically lower than in the group without conduction block. Further analyses may be performed to understand the relation of conduction defects with mortality due to the fact that thrombolytic therapy has the ability to reduce mortality.
