Cardiovascular diseases are the most prominent cause of death in patients with schizophrenia. Frontal QRS-T (fQRS-T) angle is a novel marker of myocardial depolarization and repolarization heterogeneity. Recent studies have indicated that the fQRS-T angle is associated with some cardiovascular abnormalities. Read More

Aim    To determine existence of a relationship between any clinical, echocardiographic and coronarographic factors and increased spatial QRS-T (sQRS-T) angle and frontal QRS-T (fQRS-T) angle in patients with anterior myocardial infarction.Material and methods    This study included 137 patients aged 62 [53; 72] years with anterior acute myocardial infarction managed at the A.L.

Background: QRS distortion (G3I) and frontal QRS-T angle (fQRS-T angle) are both electrocardiographic (ECG) signs of ongoing ischemia and depolarization-repolarization heterogeneity, which always occur in patients with ST-segment elevation acute myocardial infarction (STEMI).

Methods: We retrospectively collected 592 STEMI patients who underwent coronary angiography and follow-up for 42 months. 1. Read More

Objective: Frontal plane QRS-T (fQRS-T) angle is a marker of ventricular repolarization heterogeneity and increased fQRS-T angle is associated with arrhythmias, adverse events and mortality. However, little is known about the importance and usefulness of fQRS-T angle in hypertensive patients. The present study aimed to investigate the association between blood pressure (BP) levels and fQRS-T angle. Read More

Aim      To identify clinical, echocardiographic, and angiographic factors related with an increase in the frontal QRS-T angle (fQRS-T) and the spatial QRS-T angle (sQRS-T) in patients with inferior myocardial infarction.Material and methods  The study included 128 patients aged (median [25th percentile; 75th percentile]) 59.5 [51.
