The frontal QRS-T angle is an electrocardiographic measurement that reflects the spatial relationship between the depolarization and repolarization vectors in the heart. It is determined by the angles between the QRS and T wave vectors in the frontal plane. A wider QRS-T angle is associated with increased ventricular ectopic activity, impaired left ventricular function, and increased risk of cardiovascular diseases (CVDs). Several studies have suggested that a wider frontal QRS-T angle is associated with an increased risk of developing CVDs, including myocardial infarction, heart failure, and sudden cardiac death. Overall, the evidence suggests that the frontal QRS-T angle is a useful marker of CV risk and may have important clinical implications for the prevention and management of CVDs. However, further research is needed to fully understand the relationship between the QRS-T angle and CVD, and to determine the optimal use of this marker in clinical practice.
