This study was done on 200 normal healthy individuals both males and females, 56 females and 144 males within the age groups from 16 years to 48 years were taken after careful clinical examination and ruling out any cardiac abnormality in particular, and others in general.. It is well known that pulmonary, endocrinal, renal and electrolyte abnormalities can show changes in the ECG pattern. Symptomatic individuals of any system involvement were not included in this study. Aims & Objectives: To analyze the pattern of Rate, Rhythm, Axis, PR Interval, QRS duration, QT duration, PR and ST segments of 12 lead ECG to note any abnormalities in above parameters , their relation to age, various types of abnormality and it is a normal variant or associated with diseased state. Material & Methods: The 12 lead ECG was taken for this study with 10 mm standardization.12- lead ECG was done. Observations & Results: We observed abnormalities like Sinus Tachycardia, Sinus Bradycardia, Sinus arrhythmias, T wave inversion, Coving ST elevation, RsR pattern, LVH and Rvh Conclusion: ECG varies from individual to individual even in normal individuals. Majority of the ECGs in normal individuals shows a pattern, which falls within normal range. A considerable percentage of individuals deviate from the normal pattern So understanding normal ECG and deviations in normal individuals is very important to interpret the diseased states & treating them.
