athlete's heart

[ath′lēts]
an enlarged but otherwise normal heart of an athlete trained for endurance. It is characterized by a low heart rate, an increased pumping capacity, and a greater ability to deliver oxygen to skeletal muscles. It may sometimes be confused with left ventricular hypertrophy. Also called athletic heart syndrome (AHS).

athlete's heart

Athletic heart syndrome Sports medicine A heart typical of trained athletes, and characterized by ↑ left ventricular diastolic volume and ↑ thickness of the left ventricular wall, as seen by 2-D echocardiography; arrhythmias seen in athletes' hearts are usually benign and include sinus bradycardia, wandering pacemaker, cardiac blocks, nodal rhythm, atrial fibrillation, ST segment and T-wave changes, ↑ P wave amplitude, right ventricular hypertrophy. See Sudden unexplained nocturnal death.

ath·lete's heart

(ath'lēts hahrt)
Nonpathologic enlarged heart in athletes reflecting specific adaptation to prolonged training. Manifestations in response to resistance training are thickened left ventricular wall and concentric hypertrophy, and in response to endurance training include enlarged left ventricular cavity and eccentric hypertrophy.
See: hypertrophy

athlete's heart

hypertrophy of the muscle of the left ventricle as a physiological response to training, especially endurance training. It is not considered to be pathological. Results in slowing of heart rate and changes characteristic of hypertrophy in the electrocardiogram (ECG).
