ObjectivesThis study was done with the objective to identify the determinants of mild, moderate and frequent burdens of premature ventricular contractions (PVCs) which may guide the health care professionals to stratify the high risk patients on basis of their symptoms.MethodsIt was a cross sectional descriptive study conducted in Islamic International Medical College (IIMC) in collaboration with Armed Forces Institute of Cardiology (AFIC) from 18th April 2016 to 20th March 2018. It comprised 60 diagnosed patients of PVCs, divided into three groups on the basis of their PVCs burden determined by Holter monitoring report. Each group of mild (Group-A), moderate (Group-B) and frequent burden (Group-C) constituted 20 patients having PVC burden<10%, 10-20% and >20% respectively. All patients were evaluated for their symptoms by a cardiologist. Statistical analysis was done to determine the association of patient's symptom and age with mild, moderate and frequent PVCs burden.ResultsPVCs were significantly associated with presence of symptoms as compared to asymptomatic patients. While no significant correlation of age or any specific symptom (palpitations, chest pain, dizziness, shortness of breath) was found with mild, moderate and frequent PVCs burden with p-value of 0.466.ConclusionsMild, moderate or frequent PVCs burden are not associated with any specific symptom predominantly or old age. So, it is equally important for all the patients presenting with any symptom of palpitations, chest pain, dizziness or shortness of breath to undergo the work up of PVCs, irrespective of their age.Copyright: © Pakistan Journal of Medical Sciences.
