The objectives, subjects and methods of the CSIK-CRP study have been previously described. This analysis was conducted on participants of the Cardiological Society of India Kerala Chapter Coronary Artery Disease and Its Risk Factors (CSIK-CRP) study that evaluated the prevalence of coronary artery disease (CAD) and its risk factors in Kerala, a southern state of India. Early repolarisation pattern was similar to rest of Asian population, but significantly less than the Caucasian population Brugada pattern occurred more often than in the west, but much less than the Far East population. Brugada and early repolarisation patterns occurred in 1.06% and 1.56% respectively, equal in both age groups, but markedly higher in men. The overall prevalence of atrial fibrillation was 0.32% which was markedly lower than the western data. Sinus tachycardia and low voltage QRS occurred more often in women. QRS axis deviation, first degree AV block, fascicular blocks, incomplete right bundle branch block, sinus bradycardia and ST elevation in the anterior chest leads were markedly higher in men. The overall prevalence of ECG abnormalities (39.9%) was higher in men (47.24% vs. Electrocardiograms were analyzed for abnormalities in 4630 participants (women 59.6%). In this cross-sectional study of men and women between the ages 20 to 79 years, ECGs recorded digitally were analyzed using the Minnesota code. ![]()
