Abstract

Obiective. The authors investigated the successful rate and safety in procedures of permanent pacemaker implantation. Methods and resultthe authors had stadied, description, prospective, reviews results of pacemaker implantion from 2011 to 2012. A total of 50 patients aged 64,42 + or - 15,56 years, the oldest patient is 88 years old, the youngest one is 18 years old, the sick sinus syndrome are 30 patients (60 percent), there are 18 cases (36 percent) with AV blocking stage III, and 2 cases (4 percent) in stage II-mobitz II. Models of pacemaker: 15 patients (30 percent) with mode WI, 1 patient (2 percent) with the mode WI MRI, 12 patients (24 percent) have been implanted the mode WIR, 5 patients (10 percent) of mode WIR MRI, 1 patient (2 percent) with the mode VDDR, 13 patients (26 percent) are the mode DDD, 1 patient (2 percent) is pacing in mode DDDR, the mode AAIR is 1 patient (2 percent). The success rate is 100 percent, there is only 1 case to slip tip of electrode lead to come out, 2 hours after implantation,the authors conducted pacemaker implantation as soon as discovered.the authors did not encounter any cases have complications such as (heart perforation, pericardial effusion, pleural effusion, pleural gas, venous thrombosis, pulmonary infarction, ventricular tachycardia, diaphragmatic stimulation, hematoma). The authors met 01 cases of the syndrome caused by pacemaker, are implanted under the mode WI, however after 3 months, this patients relatively well tolerated. The ventricular stimulation threshold, average 0,62 + or - 0,15 mV, the highest threshold of 0.9mV, the lowest threshold of 0.4 mV. The atrial stimulation threshold, average 0,76 + or - 0,21mV, the highest threshold is l,2mV, the lowest threshold is 0,4mV.the authors showed that the ventricular and atrial stimulation threshold increased after few days, but after 6 weeks, 3 months, 6 months, then the stimulus threshold was fairly stable. The average duration of the QRS interval is 131,12 + or - 5,93 ms, the shortest time is 97ms, the longest time is 150 ms, 2 cases (4 percent) is pacing in right ventricular apex pacing, the most patients (94 percent) is pacing in right ventricular septum, 01 case (2 percent) with right ventricular outflow tract pacing subject. Conclusion: The permanent pacemaker procedure is high successful rate, safe and effective for patients with bradycardia, for the maintenance of atrioventricular synchronization,the authors need to use the mode VDD (R), DDD (R).
