Overview
Athletic strain causes a number of functional and morphological changes in the heart which represent physiological mechanisms of adaptation. The ECGs of sporting population often show changes which require correct interpretation in terms of their significance. Asymptomatic sinus arrhythmias, bradycardias, the 1st degree AV block and the 2nd degree intermittent Wenckebach AV block are frequent heart rate disorders and do not normally require any special measures. In the case of the Mobitz 2nd degree AV block and the complete AV block, it is necessary to perform additional cardiac examination (echocardiography, load ECG test, Holter ECG monitoring) and to decide on further steps on an individual basis.
