Background and Objective: Premature ventricular complex (PVC) burden exhibits one of three circadian types, classified as fast-type, slow-type, and independent-type PVC. It is unknown whether PVC circadian types have different heart rate variability (HRV) parameter values. Therefore, this study aimed to evaluate differences in HRV circadian rhythm among fast-, slow-, and independent-type PVC. Methods: This cross-sectional observational study consecutively recruited 65 idiopathic PVC subjects (23 fast-, 20 slow-, and 22 independent-type) as well as five control subjects. Each subject underwent a 24-hour Holter to examine PVC burden and HRV. HRV analysis included components that primarily reflect global, parasympathetic, and sympathetic activities. Repeated measures analysis of variance was used to compare differences in HRV circadian rhythm by PVC type. Results. The average PVC burden was 15.7%, 8.4%, and 13.6% in fast-, slow-, and independent-type idiopathic PVC subjects, respectively. Global, parasympathetic nervous system, and sympathetic nervous system HRV parameters were significantly lower in independenttype PVC versus fast- and slow-type PVC throughout the day and night. Furthermore, we unexpectedly found that tendency towards sympathetic activity dominance during nighttime was only in independent-type PVC. Conclusion The HRV parameters are reduced in patients with independent-type PVC compared to fast- and slowtype PVC. Future research is warranted to determine possible differences in the prognosis between the three PVC types.

Introduction: Depression is a common mental disorder in primary care settings both globally and locally. Even with considerable impacts on patients’ quality of life and public healthcare costs, most people with depression do not receive evidence-based treatment. Integrating mental healthcare services into primary care is essential to address the treatment gap for depression. As counsellors and care coordinators, family physicians have a vital role in providing primary mental healthcare services. This study aims to assess Indonesian family physicians’ knowledge of depression and identify the associated factors. Methods: This cross-sectional observational study included a total of 83 family physicians from the Association of Indonesian Family Physicians. Data were collected using online questionnaires, including demographic and knowledge assessment instruments and the Care Coordinator Scale (CCS). Descriptive and multiple linear regression analyses were performed. Results: The knowledge of depression, particularly in terms of prevention, diagnosis, pharmacological treatment, and post-referral treatment, was insufficient among the family physicians. The medication education (P=0.006) and follow-up care plan (P=0.04) domains of the CCS were associated with the family physicians’ knowledge of the management of depression in the linear regression analysis (R2=0.077). Conclusion Interventions to improve Indonesian family physicians’ knowledge of depression, focusing on medication/pharmacological treatment and considering them as care coordinators, are essential.
