Changes in ECG pattern with advancing age

Area of Science:

• Cardiology
• Geriatrics
• Preventive Medicine

Background:

• Cardiovascular disease (CVD) prevalence increases with age due to aging processes and risk factors.
• Population demographics show a growing elderly segment, necessitating cardiac health evaluations.
• Aging impacts cardiovascular system, altering CVD epidemiology, clinical presentation, treatment response, and prognosis in older adults.

Purpose of the Study:

• To evaluate the cardiac status of the elderly population.
• To assess the prevalence of electrocardiogram (ECG) abnormalities in relation to age.
• To determine the utility of resting ECG in identifying asymptomatic heart disease in older adults.

Main Methods:

• A study was conducted on 400 healthy, asymptomatic subjects aged 45-74 years in Solapur city.
• Resting 12-lead electrocardiograms (ECGs) were recorded for all participants.
• ECGs were coded and classified for abnormalities using the Minnesota code system.

Main Results:

• A strong correlation was observed between electrocardiographic abnormalities and advancing age.
• The incidence of abnormal ECGs paralleled age progression in the study population.
• ECG proved a reliable indicator of heart disease, even in individuals aged 60-70 years.

Conclusions:

• Resting ECG effectively identifies subgroups at high risk for cardiovascular diseases among asymptomatic individuals.
• The ECG is a valuable office-based tool for detecting symptomless heart disease.
• ECG findings can guide referrals for further non-invasive testing or cardiac catheterization.
