Right precordial lead (V4R) ST-segment elevation is associated with worse prognosis in patients with acute anterior myocardial infarction.

摘要

I would like to commend Gollob et al. (1) for their attempt to generate criteria on how to diagnose short-QT syndrome (SQTS), but I would also like to point out some of the shortfalls and errors in their report.In Table 1 of their report, at least 1 patient appears to have been included twice (Patients #23 and #49) with different ages and different QT intervals. Patient #46, published in 2008, was a 22-year-old man who "experienced unheralded syncope for the first time while driving, resulting in a motor vehicle accident" which in the current report is categorized as aborted cardiac arrest. This patient had no documented arrhythmias and no short QT interval on electrocardiography (QT interval 366 ms at 66 beats/min).
