exercise-induced cardiac stunning
Temporary reversible myocardial dysfunction following intense exercise without permanent cardiac damage.
Full Definition
Exercise-induced cardiac stunning refers to transient left ventricular dysfunction that can occur after prolonged, intense exercise such as marathon running or ultra-endurance events. This phenomenon is characterized by temporary reduction in cardiac function that typically resolves within 24-48 hours without permanent sequelae. The condition is thought to result from exercise-induced oxidative stress and transient myocardial ischemia during extreme physical exertion.
Usage
Usage note: Distinguish from permanent cardiac dysfunction by noting the reversible nature and typical timeframe for resolution.
