Early repolarization on an ECG

Early repolarization on an ECG (Electrocardiogram) refers to a pattern that is usually considered normal, but in some cases, it may be associated with an increased risk of arrhythmias. It is most commonly seen in young, healthy individuals, especially in athletes. Here’s a breakdown of what you might find on the ECG when early repolarization is present: Key Features: J-point elevation : The point where the QRS complex (the main spike on the ECG) transitions to the ST segment shows an upward deflection, which is often greater than 1 mm in at least two contiguous leads. ST segment elevation : The ST segment itself may have a slight concave upward shape (known as "upward concavity"). T wave changes : The T wave may be more pronounced or prominent in the leads with J-point elevation, especially in the inferior or lateral leads. Common Locations: Early repolarization is typically seen in the inferior leads (II, III, aVF) and lateral leads (V4-V6) . It can also be fou...
