[The effect of extracorporeal piezoelectric lithotripsy on cardiac activity]

To evaluate cardiac effects of shock waves, 40 patients with uroliths (10 subjects with and 30 without arrhythmia) were examined during their exposure to remote electropiezolithotripsy (Piezolith-2300 unit). Arterial pressure and ECG were registered before, during (upon 1500 and 3000 impulses) and after the session. Except a slight deceleration of the heart rate, no cardiac disorders significant clinically were reported.
