###Human: What does ECG taken for chest pain indicate? ###Assistant: Hi. Significant findings in ECG are: 1. Early repolarization in V5 and V6. This is a normal finding at your age. 2. Deep S wave in lead V3. This can suggest left ventricular hypertrophy (by Cornell voltage criteria). However, there are no other changes in ECG to suggest LVH and deep S wave can sometimes be seen normally in young people. You can get echocardiography to remove any doubt regarding LVH (left ventricular hypertrophy). Echocardiography.
