Abstract Background The autonomic nervous system involves the genesis of premature ventricular contractions (PVCs). Previous studies demonstrated that heart rate (HR) dependency of idiopathic PVCs has different autonomic mechanisms. Recently, the bisoprolol patch, a novel transdermal β1-blocker formulation containing bisoprolol, became clinically available. We examined the efficacy of the bisoprolol patch for treating frequent PVCs in patients without structural heart disease (SHD) regarding the HR dependency of PVCs. Methods This prospective study included 44 consecutive patients without SHD (25 men, mean age, 63.6 ± 12.3 years) with PVC counts≥3000 beats as measured by 24-hour Holter electrocardiograms (ECGs). PVCs were divided into positive HR-dependent PVCs (P-PVCs) and non-positive HR-dependent PVCs (NP-PVCs) based on the relationship between the hourly PVC density and hourly mean HR. A bisoprolol patch was administered once daily at a dose of 4 mg. The 24-hour Holter ECGs were performed before and 1 month after the initiation of the therapy. Results In 44 patients, there were 24 P-PVCs and 20 NP-PVCs. The bisoprolol patch reduced the PVC count significantly (from 16,563 ± 10,056 to 7892 ± 8817 beats/24 hours, p < 0.001) in the P-PVC group, while the PVC count did not change significantly (from 16,409 ± 9571 to 13,476 ± 12,191beats/24 hours, p = 0.34) in the NP-PVC group. Moreover, in the P-PVC group, the patients with mean HRs ≥80 beats/minute had a significantly higher percent improvement in the PVC count than those with mean HRs
