Abstract
Disclosed is a system for detecting pathophysiological cardiac conditions. The system comprises a diagnostic device that contains electronic circuitry that can detect a cardiac event such as an acute ischemia. The cardiac diagnostic device receives electrical signals from subcutaneous or body surface sensors. The cardiac diagnostic device includes a processor that computes a measure of QRS curvature and applies an ischemia test based on the measure of QRS curvature to determine a likelihood of ischemia.
