Early Repolarization Pattern (ERP)

The purpose of this study was to investigate the relationship between ER prevalence and QTc interval in healthy subjects. Method Study Population This study included 80 healthy subjects with an early repolarization electrocardiogram (n = 40) and a normal electrocardiogram (n = 40). The study group matched on a one-to-one basis based on age and gender. In short, in addition to receiving a standard resting 12-lead electrocardiogram, subjects completed a questionnaire on their health habits, known diseases and medications.

QTc extension (men usually> 440 ms, women> 460 ms, but all intention and purpose> emergency room> 480 ms) means long repolarization. Long-term repolarization means that the initial depolarization takes longer during repolarization (the so-called R-on-T phenomenon), causing or causing a variable storm. This risk is higher in bradycardia, which allows the longer repolarization time in the cardiac cycle to cause depolarization.

Each cardiac cycle consists of electrical (depolarization and repolarization) and mechanical processes (contraction and relaxation). Depolarization causes contractions, also known as contraction, evacuates blood from the heart, repolarizes, relaxes or relaxes and fills the heart. The function and efficiency of the heart depends on the amount of blood that the heart receives (preload), the pressure required to deliver blood from the heart (afterload), and the heart rate (heart rate). It is also important to note that the health of the heart is the product of oxygen supplied to the myocardium (through the coronary artery).
