Physiology

Premature ventricular contraction

ECG trace showing a premature ventricular contraction as an early, wide, bizarre high-amplitude QRS complex occurring before the next expected normal beat. The QRS-T complex is broader and larger than surrounding normal beats, lacks a preceding P wave, and is followed by a prominent abnormal T wave oriented opposite the main QRS deflection.
