Silent Signals: Exploring ECG Abnormalities in Asymptomatic Healthcare Professionals at MTI Bannu

Background: Electrocardiography (ECG) plays a vital role in diagnosing cardiovascular diseases, a leading global health burden. Healthcare professionals, due to occupational stresses, may have an increased risk of cardiovascular abnormalities, particularly in resource-limited settings like Pakistan. Understanding ECG patterns in this group is essential for targeted interventions. Objective: To determine the frequency of ECG patterns in asymptomatic healthcare professionals at MTI Bannu. Materials and Methods: This descriptive cross-sectional study included 185 asymptomatic healthcare professionals, in three allied hospitals of Medical Teaching Institutions (MTI) Bannu. Data were collected using a closed-ended questionnaire and analyzed with SPSS version 26. ECG patterns were recorded with a portable ECG machine. Results: Among the participants, 143 (77.3%) exhibited normal ECG patterns. Of 45 doctors, 40 (88.8%) had normal ECGs, while 5 showed abnormalities, including sinus arrhythmias (4.4%) and bradycardia (2.2%). Among 45 medical students, 31 (68.9%) were normal, with abnormalities including right axis deviation (11.1%) and early repolarization (4.4%). Of 57 paramedics, 45 (78.9%) had normal ECGs, while abnormalities included sinus tachycardia (1.8%) and premature ventricular contractions (3.5%). Among 38 support staff, 34 (89.5%) were normal, with abnormalities observed in 4 participants (10.5%). Conclusion: A notable proportion of healthcare professionals, despite being asymptomatic, exhibited ECG abnormalities such as arrhythmias, bradycardia, and hypertrophy. These findings highlight the importance of regular ECG screening in this population to facilitate early detection and intervention for potential cardiovascular risks.
