PP-129 An Unusual Pacemaker Syndrome Case: Recurrent Pericardial Tamponade




Introduction


Pacemaker syndrome is an atrioventricular dyssynchrony resulting from concurrent contractions of the atria and ventricules due to retrograde ventriculoatrial conduction. So far, pericardial effusion due to pacemaker syndrome is not reported in the literature.




Case


61 year-old male having CABG and VVI-ICD implanted after MI was admitted with dyspnea. Echocardiography and tomography showed pericardial tamponade (figure d). EF was 35 %. 1150 ml. serous pericardial effusion was drained. The patient was readmitted with dyspnea 45 days later. Pericardial tamponade was seen with echocardiography (figure e-f) and effusion was drained. Electrocardiography showed pacemaker rhythm with atrial activity consistant with retrograde p waves (figure a ). Pacemaker lower rate was reduced to 40 and sinus ritm at 44/minutes appeared. He was readmitted 20 months later. Echocardiography showed pericardial effusion and tamponade( fig g). ECG showed ventricular pacemaker rhythm at the rate of 45 (figure b ). Pericardial effusion was drained (figure h). Pacemaker lower rate was reduced to 30 beats/minute and a sinus rate with a rate of 37 beats/minute appeared (figure b ). Patients was thought to have pacemaker syndrome due to retrograde ventriculoatrial conduction. EPS showed retrograde conduction over Atrioventricular node. Amiodarone was causing bradycardia and stopped. After 4 mounths, rhythm was sinus, no pericardial effusion was present (figure c-i).
