Insights
Electrocardiograms (ECGs) in centenarians show distinct patterns compared to younger elderly individuals, revealing age-related changes independent of heart disease. These findings highlight unique cardiac characteristics in extreme longevity.
Area of Science:
- Cardiology
- Gerontology
- Medical Diagnostics
Background:
- Centenarians represent a model for successful aging, yet often exhibit cardiovascular diseases.
- Electrocardiogram (ECG) findings in centenarians can reflect normal aging or underlying pathologies.
- Identifying ECG features specific to extreme age is crucial for understanding aging processes.
Purpose of the Study:
- To identify electrocardiogram (ECG) features uniquely associated with extreme age in centenarians.
- To differentiate age-related ECG changes from those caused by cardiac diseases in the oldest old.
Main Methods:
- Retrospective analysis of 55 centenarians hospitalized between 2000 and 2010.
- Matched comparison with three octogenarians per centenarian, controlling for hypertension, aortic stenosis, heart failure, and ischemic heart disease.
Main Results:
- Centenarians had higher heart rates and more frequent left QRS axis deviation and Q waves than octogenarians.
- Atrial premature beats were more common in centenarians, while atrial fibrillation was less frequent.
- A strictly normal ECG was rarer in centenarians (4%) compared to octogenarians (15%).
Conclusions:
- Abnormal ECG findings are prevalent in centenarians.
- ECG characteristics in centenarians differ significantly from younger elderly individuals.
- These distinct ECG differences appear unrelated to the presence of diagnosed cardiac diseases.
Background:
Centenarians have been proposed as a model of successful aging but recent studies suggest a high prevalence of cardiovascular diseases. Some findings on their electrocardiograms (ECGs) are simply age-related and others mirror underlying diseases. We aimed to identify ECG features truly associated with extreme age.
Methods:
Retrospective analysis of 55 centenarians hospitalized between January 2000 and June 2010. Each centenarian was matched with three octogenarians according to gender, presence of hypertension, aortic stenosis, heart failure, and ischemic heart disease.
Results:
A history of hypertension was present in 32 (58%) centenarians, aortic stenosis in 6 (11%), heart failure in 8 (15%), and ischemic heart disease in 6 (11%). Centenarians had a higher heart rate than octogenarians (81 ± 15 bpm vs. 72 ± 15 bpm, respectively, P < 0.001) but were less frequently on beta-blockers (7% vs. 36%, respectively, P < 0.001). Centenarians displayed more frequently atrial premature beats than octogenarians (18% vs. 3%, respectively, P < 0.001) but tended to have less atrial fibrillation (15% vs. 22% respectively, P = 0.21). Centenarians had more frequently left QRS axis deviation (48% vs. 28%, P = 0.009) and Q waves (14% vs. 1%, P = 0.02). QT interval was more prolonged in centenarians (446 ± 42 ms vs. 429 ± 39 ms, P = 0.008). Two centenarians (4%) and 24 (15%) octogenarians had a strictly normal ECG (P = 0.02).
Conclusions:
Abnormal ECG is a common finding in centenarians, with different characteristics than in younger elderly individuals. These differences are unrelated to the presence of cardiac diseases.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
