Abstract:
Objective To study the feasibility and safety of coronary sinus (CS) ventricular pacing comparing with traditional right ventricular (RV) pacing in ordinary pacing treatment.Methods Sixty-one patients with an indication of pacemaker implantation were randomized into traditional RV pacing group and CS ventricular pacing group.The success rate,complications,preoperative and postoperative QRS wave duration and pacemaker parameters were compared between the two groups.Results (1) The instant success rate in traditional RV pacing and the CS pacing groups were 100％ and 68.97％ (P＜0.01);the surgical success rate was significantly higher by using left ventricular electrode than the ventricle tined electrode in CS pacing group (85.71％ and 25％,P＜0.05).There was no significant difference in the incidence of complications between the two groups (P＞0.05);(2) The increase of QRS complex width at postoperative 1 month in CS pacing group is significantly less than the RV pacing group (P＜0.05);(3) Although the pacing threshold and electrode impedance during operation,postoperative 1 month and 3 months in CS pacing group were higher than RV pacing group (P＜0.05),the CS pacing was effective.Conclusion The CS ventricular pacing is as safe and effective as traditional RV pacing,and is more consistent with physiological ventricular activation sequence.Using left ventricular electrode can significantly improve the success rate of CS ventricular pacing.
