An implanted programmable ambulatory electrocardiography (AECG) patient monitoring device that senses and analyzes electrocardiographic signals from at least one subcutaneous precordial sensor chronically and frequently to detect electrocardiogram and physiological signal characteristics predictive of malignant cardiac arrhythmias. The device includes telemetric capabilities to communicate a warning signal to an external device when such arrhythmias are predicted.
