Prevalence of ECG abnormalities in competitive athletes has been studied by Pellicia et al.<cite>Pellicia</cite>(see table below). ECG abnormalities in their study increased with age and level of exercise. In young amateur athletes they found ECG abnormalities in about 7%, a number that rose to 40% in "adult elite athletes". Especially [[RBBB]] and [[lvh|left ventricular hypertrophy]] were often seen. | Prevalence of ECG abnormalities in competitive athletes has been studied by Pellicia et al.<cite>Pellicia</cite>(see table below).

A recent study investigated ECG and echocardiographies in male athletes of African / Afro-Caribbean origin and found frequent T wave inversions in leads V1-V4. Significant ST elevation was present in 63.2% and LVH in 23.2%.<cite>Papadakis</cite>. | |||
Recently fierce debate has been going on about whether an ECG should be part of the screening of apparently healthy young sporters. In Italy this screening is compulsory by law and this country is a strong advocate of the use of an ECG as part of this screening. However, others<cite>Chaitman</cite> have stated that costs are too high for the yield (expressed in dollars per prevented sudden cardiac death) and an ECG is not included in the screening protocol of the American Heart Association.<cite>Maron</cite><cite>Myerburg</cite> | Recently fierce debate has been going on about whether an ECG should be part of the screening of apparently healthy young sporters.
