Abstract:
This study aimed to investigate the effects of radiofrequency catheter ablation ( RFCA ) and clinical and electrophysiological characteristics in symptomatic patients with premature ventricular contractions ( PVC s) from near the His‐bundle (His‐ PVC s). Methods The patient characteristics, prevalence of complications with any life style related disease ( ALSRD ) including hypertension, dyslipidemia, or diabetes mellitus, and/or cardiovascular disease ( CVD ) including coronary artery disease, cerebrovascular disease, renal dysfunction, or cardiomyopathy, clinical status, frequency of PVC s evaluated by 24hour Holter monitoring, echocardiography including the left ventricular diastolic dysfunction ( LVDD ) parameters, and electrophysiological findings were evaluated in 14 consecutive symptomatic patients with His‐ PVC s. Results The prevalence of males, being elderly and/or slightly obese, current and/or history of smoking, ALSRD or CVD related complications, and LVDD probably resulting from ALSRD and/or CVD complications were higher in patients with His‐ PVC s. RFCA of His‐ PVC s steadily decreased the PVC frequency and improved the systolic function, LV dilation, and clinical status, but not the LVDD . There was a significant relationship between the accordance rate of the QRS polarity between sinus rhythm and His‐ PVC s and the distance between the successful ablation site and His‐bundle. Conclusion The analysis of the QRS duration and accordance rate of the QRS polarity between sinus rhythm and His‐ PVC s before the RFCA may help to determine the distance between the origin of the PVC s and His‐bundle. Further, the appropriate ablation catheter may be selected during the RFCA procedure. Finally, RFCA may be one of the most effective, feasible, and safest therapies for symptomatic patients with His‐ PVC s.
