Objective:To observe the effect of closed-loop stimulation (CLS) on rapid atrial arrhythmia.Methods:From August 2016 to March 2018, 30 patients with CLS dual chamber pacemaker implanted in China-Japan Friendship Hospital were selected in this study. The average age was (64.3±14.7) years, including 18 males. The patients were divided into A group (DDD-CLS mode before DDDR mode, both mode for 3 months) and B group (DDDR mode before DDD-CLS mode, both mode for 3 months) by simple randomization with single blind and crossover design.We observed and compared the percentage of atrial and ventricular pacing rate and the frequency and duration of auto mode switch (AMS) and atrial tachycardia burden percentage of the same patient under DDD-CLS mode and DDDR mode by pacemaker programmer.Results:Comparing to DDDR mode, DDD-CLS mode showed higher atrial pacing rate (66.5%±11.8% vs. 55.8%±14.0%, OR=1.30, 95% CI 1.06-1.73, P=0.007) , lower AMS counts[ (369±409) times vs. (596±761) times, OR=0.62, 95% CI 0.32-0.88, P=0.025]and lower atrial tachycardia burden percentage (17.9%±3.6% vs.29.3%±7.3%, OR=0.61, 95% CI 0.18-0.71, P=0.034) . Conclusion:CLS function may reduce the rapid atrial arrhythmia burden in patients treated with permanent dual chamber pacemaker.

Objective To investigate the efficacy and safety of optimized axillary vein puncture for cardiovascular implantable electronic device (CIED) lead implantation.Methods Two hundred and twenty patients with indications of CIED implantation were randomized into optimized axillary vein puncture group (experimental group) or subclavian vein puncture group (control group).The efficacy and safety of the two techniques were compared.Results The success rate (96.6% vs.96.0%),one-time success rate (68.8% vs.69.3%) and X-ray exposure time[(152.1±32.7) s vs.(145.6±46.1) s]of axillary vein puncture and subclavian vein puncture were similar between the two groups.There were one case of pneumothorax and three cases of lead operating diff culties in subclavian vein puncture group.No complication occurred in axillary vein puncture group.In the follow-up,Electrode crash syndrome occurred in two patients in the control group.The incidence of complications showed a decreased tendency in the optimized axillary vein puncture group(1.82% vs.7.27%,P=0.11).Conclusion Optimized axillary venous approach may be superior to traditional subclavian vein approach for pacemaker lead placement.
