Abstract
Background: The 12-lead ECG is the primary clinical tool for non-invasive assessment of cardiac electrical function. Before any surgery, ECG is commonly used in pre-operative check-up. Therefore pre-operative check-up of large number of people can be a valuable tool for accurate estimates of the prevalence of ECG abnormalities of general population. Objectives: To observe the extent of ECG changes in a group of population undergoing ENT surgery and to describe the prevalence of changes in relation to age and sex. Methods: 704 consecutive adult stable patients were included between age of 20 – 60 years without previously diagnosed case of any other systemic diseases who came to this hospital for elective surgical procedures and were investigated with new ECG for pre-operative check-up in private Hospital between January 201 to December 2010. Results: Total number of ECG recordings were 704; out of them 479 were male & 225 were female. Among 704 ECG recording 486(69.03%) were normal. The number of old myocardial infarction (MI) was in 36 cases (5.11%). Cardiac Ischaemia observed by ST depressions/T inversion was present in 15 cases (2.13%). Conclusion: The observation of the study is concludes that nearly 70% of all asymptomatic people (between 20 – 60 years) possessing normal ECG but Ischaemic changes (like Q wave/ST depression & T inversion/ LBBB) was present in about 8% cases. ECG changes of IHD (Ischaemic Heart Disease) increases with age and male groups at higher risk of developing IHD. Key Words: ECG; Pre-operative Check-up; Myocardial Infarction (MI).

Summary
The 12-lead ECG (electrography) is the primary clinical tool for non-invasive assessment of cardiac electrical function 1. Bangladesh Chest X-ray & ECG are primary tools for screening heart diseases. These two investigations are largely used in pre-operative check-up. Preoperative check-up of large number of people can be a valuable tool for accurate estimates of the prevalence of ECG abnormalities in general population. Large number of such studies has been done in different centers, but most of them have done in western countries. The 12-lead ECG is the primary clinical tool for non-invasive assessment of cardiac electrical function. Pre-operative check-up of large number of people can be a valuable tool for accurate estimates of the prevalence of ECG abnormalities of general population
