•1. Patients diagnosed with premature ventricular contractions (PVCs) and ventricular tachycardia (VT);
•2. Patients aged between 18 and 80 years;
•3. Patients with obvious symptoms of PVCs/VT but cannot be relieved or tolerate antiarrhythmic medicine;
•4. Impaired left ventricular function or tachycardia-induced cardiomyopathy due to asymptomatic PVCs/VT;
•5. Frequent monomorphic PVCs/VT (>10000 per 24 h or burden >10%);
•6. Informed consent can be obtained.

•1. Failure or abandonment of the ablation procedure;
•2. Sustained ventricular tachycardia, Torsade de pointes, ventricular flutter or ventricular fibrillation;
•3. PVCs/VT due to reversible reasons (electrolyte disturbance, acute ischemia, hyperthyroidism, etc);
•4. Infrequent monomorphic PVCs(<10000 per 24 h);
•5. blood clots in the heart;
•6. Acute myocardial infarction(within 2 months);
•7. NYHA cardiac functional grading>=level III;
•8. Other severe cardiac dysfunction, cardiac ion channel diseases, inherited arrhythmogenic diseases and so on;
•9. complicated with other severe diseases (e.g. hepatic and renal dysfunction, malignant tumor);
•10. pregnancy or be allergic to iodic contrast medium.
