Probability of incident outcomes by the presence of ectopy on the baseline standard ECG. Ectopy was defined as the presence of at least 1 PAC (in the AF analysis) and at least 1 PVC (in the HF analysis). Models were adjusted for age, sex, race, hypertension, diabetes mellitus, myocardial infarction, coronary artery disease, body mass index, study center, and heart failure (in AF outcome analyses) and AF, baseline left ventricular ejection fraction, and beta‐blocker use (in heart failure outcome analyses). AF indicates atrial fibrillation; ARIC, Atherosclerosis Risk in Communities study; CHS, Cardiovascular Health Study; HF, heart failure; PAC, premature atrial contraction; PVC, premature ventricular contraction.
