Objective To explore the clinical values of holter among different types of pacemaker postoperations .Methods Selected 120 patients undergoing pacemaker implantation from November 2013 to October 2014 ,who also received holter examina-tion after operation .The sensing and pacing dysfunction and pacemaker associated arrhythmia were analyzed according to their hol-ter results .Results In the DDD group ,the detection rate of the ventricular premature contraction ,the atrial premature contraction , the paroxysmal atrial tachycardia ,the paroxysmal atrial fibrillation and the paroxysmal supraventricular tachycardia were 38 .9% , 44 .4% ,8 .3% ,2 .8% and 2 .8% ,respectively .In the DDD group ,the detection rate of the sensing and pacing dysfunction and pace-maker associated arrhythmia was 69 .4% ,which was significantly higher ( P < 0 .05) than that in the VVI group (42 .5% ) ,the VVIR group(30 .0% ) ,the DDDR group(31 .3% ) and the AAI group(25 .0% ) ,respectively .In the VVI group ,the positive rate of the ventricular premature contraction ,the atrial premature contraction ,the paroxysmal atrial tachycardia ,the paroxysmal atrial fi-brillation and the paroxysmal supraventricular tachycardia were 37 .5% ,42 .5% ,10 .0% ,17 .5% and 2 .5% ,respectively .In the VVIR group ,the appearance rate of the ventricular premature contraction ,the atrial premature contraction and the paroxysmal atrial tachycardia were 25 .0% ,25 .0% and 5 .0% ,respectively .In the DDDR group ,the detectable rate of the ventricular premature con-traction ,the atrial premature contraction ,the paroxysmal atrial tachycardia and the paroxysmal atrial fibrillation were 31 .3% , 25 .0% ,12 .5% and 12 .5% ,respectively .Finally ,in the AAI group ,the detection rate of the ventricular premature contraction and the atrial premature contraction were 25 .0% each .Conclusion The clinical application of holter can evaluate the working states of different types of pacemakers ,and can monitor the sensing ,the pacing dysfunction and the pacemaker associated arrhythmia .
