This scoping review has been registered in the Open Science Framework (OSF), DOI. The findings will allow us to map out research gaps on this topic that could shape future research and ultimately clinical practice. We believe this scoping review will provide a general foundation of evidence on the potential significance of PVCs concerning its diagnostic and prognostic value among the adult patient population. Finally, critical appraisal will be conducted using a tool adapted from the Quality Appraisal Checklist by the National Institute for Health Care Excellence (NICE). A standardized data extraction form will be developed. Two independent reviewers will assess potential studies in detail against inclusion criteria. EndNote X8 will be used to manage citations, as well as for duplicates screening in addition to Microsoft Excel 2016. The study selection process will adopt the 2009 PRISMA flow diagram. A search strategy will be developed, and four major electronic databases will be searched: CINAHL, Embase, PubMed, and Web of Science Core Collection.
In identifying relevant studies, the Population-Concept-Context (PCC) framework by the Joanna Briggs Institute will be used. A scoping review framework by Arksey and O’Malley will be adopted. The primary question of this review is “what is the clinical significance of PVCs in adults?” Preparation of this scoping review will use the PRISMA-P statement. A thorough scoping review of the literature regarding the clinical significance of PVC is imperative, precisely to map out the evidence on the diagnostic and prognostic values of PVCs and to identify research gaps on this issue.
Despite these recommendations, PVC monitoring practices remain part of routine care, especially in the intensive care unit, for worry of missing potentially significant arrhythmia events. Practice guidelines for in-hospital monitoring state that monitoring for PVCs may be indicated on some patients but do not recommend continuous ECG monitoring. There is also concern that PVCs contribute to excessive alarms and lead to alarm fatigue. However, in current practice, PVCs generally do not required treatment. PVCs were thought to cause lethal arrhythmias and thus were closely monitored and treated. Premature ventricular contractions (PVCs) are one of the most common arrhythmias detected from electrocardiographic (ECG) monitoring.
