Sudden death during ambulatory monitoring in a patient with left main coronary artery disease.
A 61 year old male with left main coronary artery disease died suddenly during ambulatory Holter monitoring. The monitoring documented ST depression followed by ST elevation, followed by junctional and ventricular escape rhythms with no measurable blood pressure by cuff methods. The mechanism of sudden death in patients with left main coronary artery disease is thought to be a combination of ventricular fibrillation or bradyarrhythmia and electromechanical dissociation secondary to a sudden onset of severe pump failure.
