Objective

The aim of this study is to investigate T peak- T end interval (T p-e) on admission ECG proposed as an indicator of transmural myocardial repolarization relationship between morbidity and mortality in patients with acute pulmonary embolism patients (APE).

Materials-Methods

This study retrospectively included 340 patients with confirmed diagnosis of APE. Out of 340 patients, 272 patients were included in the study, (154 F, 118 M; mean age of 63.1 + 16.8 years). ECG recordings were obtained during the patients admission. All ECG recordings were screened using a computer at 800 dpi resolution. The Tpe/cTpe Intervals were measured with a computer program using a ruler or vernier caliper manual measuring tool to get more sensitive measurements. The QT and cQT durations, RR intervals, QRS durations and negative T scores were measured besides the Tp-e interval. The relation between measured ECG values and 30-day morbidity and mortality (hemodynamic instability requiring catecholamine support to increase blood pressure, the need for cardiopulmonary resuscitation or mechanical cardiovascular support) was examined.
