Abstract:ObjectiveT o evaluate the effectiveness of radiofrequency ablation in 14 patients with organic heart disease complicated with ventricular tachycardia in our center, and to provide a method for further improving the success rate of surgery and reducing the recurrence rate. Methods Patients with radiofrequency ablation due to organic heart disease complicated with ventricular tachycardia in the center were selected in the study. The location, strategy, success rate and recurrence rate of ablation in patients with ventricular tachycardia were analyzed. Results Fifteen patients with organic heart disease and ventricular tachycardia were followed up for radiofrequency ablation (17±3) months. There was no sustained ventricular tachycardia during follow-up, and no obvious complications occurred after operation. There was no death or bleeding. Conclusion Radiofrequency ablation is safe and effective in patients with organic heart disease and ventricular tachycardia. It can improve the chance of ventricular tachycardia and reduce the chance of sudden death.
