Patient discussions

Restriction in competitive sports is recommended in the presence of moderate left ventricular (LV) enlargement or dysfunction, uncontrolled tachyarrhythmias, long QT interval, unexplained syncope, prior resuscitation from cardiac arrest, or aortic root enlargement.[48][49]

Patients with increased adrenergic response to stress or activity demonstrated on event monitoring may benefit from lifestyle changes such as reducing alcohol, reducing stimulants such as coffee and colas, and engaging in a consistent exercise program. Athletes with MVP and ventricular arrhythmias exhibited larger LV and left atrial dimensions, along with comparable LV systolic function, and a higher occurrence of MAD (16% vs. 3%; P <0.001) when compared to athletes with MVP but no ventricular arrhythmias.[26]
