The health transition in India reflects the growing burden of cardiovascular diseases. It is well-known that there are significant and meaningful differences in the measured electrocardiogram (ECG) parameters between females and males. Specific to ECG diagnosis and ischemia, reports have indicated a higher number of false positive results in female patients than in male patients. This study was aimed at examining gender difference in the prevalence of ECG abnormality in older people who were free of coronary heart disease (CHD) and its associated risk factors.


This study was conducted in Solapur city using 400 apparently healthy asymptomatic subjects with an age range of 45 to 74 years. A resting 12-lead ECG was recorded in supine position in accordance with classical recommendations. The various ECG abnormalities were defined according to Minnesota code. The findings were analyzed using Chi Square test at P<0.05.


Out of 400 ECGs recorded, 152 showed abnormalities. The prevalence of ECG abnormalities was significantly (P<0.001) more in males than in females. Major prevalence of ECG abnormalities in males observed were LAD, LVH, sinus bradycardia, LBBB and Q/QS patterns. There was no significant gender difference in the prevalence of other ECG abnormalities.


This study has outlined the overall prevalence of ECG abnormalities in males as well as in females in Solapur city. We found highly significant (P<0.001) increase in the prevalence of ECG abnormalities in males as compare to females.
