RESUMO
Swimming differs from other forms of exercise due to its additional hydrostatic and thermal burden. It was investigated whether additional pathologic findings in comparison to history and standard exercise tests can be obtained by holter monitoring during swimming. Symptoms and exercise electrocardiogram were compared with the holter ECG during swimming in 125 patients divided into 3 groups with different diagnoses and severity of cardiac diseases. In a considerable percentage of patients ischemic changes and severe rhythm disturbances were found only during swimming with further diagnostic and therapeutic consequences, though patients with moderate and severe angina and with significant ischemic signs in the exercise test were excluded and mainly patients with slight or absent symptoms were evaluated predominantly. Thus, since swimming is a favorite leisure-time occupation also in patients with diseases of heart and circulation, holter monitoring during swimming is of diagnostic importance in the rehabilitation of these patients.
