Eligibility Criteria:
Inclusion Criteria:
1. Age 18-70 years old, body weight 45-80kg, and no sex preference.
2. Frequent premature ventricular contraction, the total number of premature ventricular beats indicated by Holter monitor greater than 3600 over 24 hours, with or without a short array of non-sustained ventricular tachycardia (more than 3, but fewer than 10 consecutive ventricular beats).

6. Sinus node dysfunction, atrioventricular block above first degree not controlled by pacemaker.
7. Complete left or right bundle branch block, or intraventricular block.
8. Hypotension, sitting resting blood pressure below 90/55mmHg.
9. Hypertension as defined by SBP\> 160mmHg and/or DBP \> 95mmHg
10. Sinus bradycardia (average heart rate lower than 50 beats/min).

13. Taking digitalis, tricyclic antidepressants, β blockers, or calcium channel blockers within 5 half-lives for a given agent.
14. Thyroid dysfunction.
15. Serious respiratory diseases, Wolff-Parkinson-White syndrome; chronic obstructive pulmonary disease, asthma requiring medication
16. Cyanotic or other uncorrected significant congenital heart disease.
17. History of allergy to sulfonamides.
18. Taking other anti-arrhythmic drugs or medications that affect cardiac electrophysiology, or stop taking the above mentioned medications less than 5 half-life of the drug ago.
19. History of taking amiodarone within 1 years.
20. Severe neurosis, menopausal syndrome, chest pain caused by cervical spondylosis.
21. Diseases of the hematopoietic system, or mental illness.
22. Current evidence of alcohol abuse or history of illegal drug abuse.
23. Women of childbearing potential who are pregnant or nursing, or women of childbearing age who are not on effective birth control (IUD or compliant use of oral contraceptives and who have a positive urine pregnancy test prior to study.
