Baseline electrocardiogram abnormalities, including isolated ventricular extrasystoles, were associated with significantly higher 13-year cardiovascular mortality compared with controls.

Do specific baseline electrocardiographic abnormalities predict 13-year cardiovascular mortality in unselected adults aged 40 to 79?
Baseline electrocardiographic abnormalities, including isolated ventricular extrasystoles in asymptomatic individuals, are significant predictors of long-term cardiovascular mortality.
In 2119 unselected Busselton subjects 40 to 79 years of age, the 13 year mortality from cardiovascular disease was significantly higher in those whose initial electrocardiogram showed Q and QS patterns, left axis deviation, ST depression, T wave depression, flat or biphasic T waves, atrial fibrillation or flutter, and ventricular extrasystoles. In angina-free subjects whose electrocardiographic codes occurred in isolation from any other electrocardiographic abnormality, ventricular extrasystoles were associated with significantly higher mortality from cardiovascular disease compared with controls.
Cullen et al. (Mon,) conducted a cohort in General population (n=2,119). Electrocardiogram abnormalities vs. Controls (without ECG abnormalities) was evaluated on 13 year mortality from cardiovascular disease. Baseline electrocardiogram abnormalities, including isolated ventricular extrasystoles, were associated with significantly higher 13-year cardiovascular mortality compared with controls.
