埋藏心脏起搏器可能伴有头昏、晕厥、呼吸困难、活动能力下降和体位性低血压等,称为“起搏器综合征”,这是由于心室收缩的同时发生心房收缩之故,心房收缩时若房室瓣恰处于关闭状态,则左右心房压力升高。该综合征见于房室逆向传导存在和心室起搏与窦性节律竞争时。双腔起搏时,心房与心室都有起搏与感知性能,使房室收缩保留正常生理顺序,心房收缩先于心室,故很少发生起搏器综合征。
Buried cardiac pacemaker may be associated with dizziness, syncope, dyspnea, decreased activity and orthostatic hypotension, etc., known as the “pacemaker syndrome”, which is due to the simultaneous contraction of the ventricle atrial contraction, so the atrium If the contraction of atrioventricular valve is closed, the left and right atrial pressure rise. The syndrome is found in the presence of atrioventricular reverse conduction and ventricular pacing and sinus rhythm competition. Double-chamber pacing, both atrial and ventricular pacing and sensing performance, so that atrioventricular retraction to retain the normal physiological sequence, atrial contraction precedes the ventricular, it is rare occurrence of pacemaker syndrome.
