Retrograde (ventriculo-atrial) conduction, premature beats, pseudotricuspid regurgitation, systolic atrial sounds and pacemaker sounds observed together in two patients with ventricular pacing.

Two patients were found to have retrograde atrioventricular conduction with premature beats during permanent ventricular pacing. In both patients the auscultatory phenomena had been heard and recorded that had been described as independent signs, but all together in the same patient had not been reported before. In one of the patients pseudotricuspid regurgitation was observed with Doppler echocardiography and the other was suspected having the same. It seems that patients with these symptoms deserve high preventive care and attention.
