Electrocardiographic findings in 204 residents of homes for the aged

Area of Science:

• Cardiology
• Geriatrics
• Medical Diagnostics

Background:

• Electrocardiograms (ECGs) are crucial for assessing cardiac health, especially in aging populations.
• Prevalence of cardiovascular disease (CVD) and ECG abnormalities increases with age.
• Limited data exists on specific ECG findings in institutionalized elderly individuals.

Purpose of the Study:

• To analyze ECG findings in a cohort of elderly individuals residing in homes for the aged.
• To determine the prevalence of cardiovascular disease and specific ECG abnormalities in this population.
• To identify ECG patterns predictive of cardiovascular disease and assess age-related ECG changes.

Main Methods:

• Analysis of electrocardiograms from 204 residents aged 60 and above in homes for the aged.
• Assessment for evidence of cardiovascular disease and various ECG abnormalities.
• Correlation of specific ECG findings with cardiovascular disease and age.

Main Results:

• 13% of subjects showed evidence of cardiovascular disease.
• 55% of ECGs exhibited at least one abnormality.
• Common abnormalities included left atrial hypertrophy, first-degree atrioventricular block, right bundle branch block, pathologic Q waves, ST-T abnormalities, and prolonged QT interval (≥10%).
• Left ventricular hypertrophy patterns, ST-T abnormalities, and prolonged QT interval were predictive of cardiovascular disease.
• Increasing age (60-100 years) correlated with prolonged PR and QT intervals and a shortened RR interval.

Conclusions:

• Electrocardiogram abnormalities are highly prevalent in institutionalized elderly individuals.
• Specific ECG findings, including left ventricular hypertrophy and ST-T abnormalities, are associated with cardiovascular disease in this demographic.
• Age-related changes in ECG intervals (PR, QT, RR) are observable in older adults.
