Abstract：Objective To discuss the effect of bipolar radiofrequency ablation treating ventricular aneurysm related ventricular arrhythmia on heart rate variability.Methods Fourteen patients who had off-pump coronary artery bypass grafting and left ventricular aneurysm repair combined with bipolar radiofrequency ablation from September 2009 to December 2014 in Beijing Anzhen Hospital,Capital Medical University were enrolled.Preoperative and postoperative heart rate variabilities were analyzed.Results There were no significant differences of the percentage of intervals ＞ 50 ms different from preceding interval,square root of the mean of the squares of successive NN interval differences,standard deviation of normal RR intervals and standard deviation average 5 min RR intervals before and after operation[2.5％ (1.0％,6.0％) vs 3.0％ (2.0％,5.0％),63.0 (40.0,93.0) ms vs 58.5 (29.0,87.0) ms,43.0 (35.0,63.0) ms vs 48.0 (35.0,65.0) ms,98.5 (91.0,125.0) ms vs 100.0 (92.0,126.0) ms] (all P ＞ 0.05).Conclusion Bipolar radiofrequency ablation for ventricular aneurysm related ventricular arrhythmia has no significant postoperative early effect on heart rate variability.
