Background: abnormal electrocardiograms (EKG) are very common in clinical practice. We want to analyze the prevalence of abnormal EKG patterns in a Caucasian population ≥ 40 years and clinical factors related to them.
Methods: A cross-sectional study endorsed by the Spanish Society of Cardiology over the Spanish population ≥ 40 years was performed. Two-stage random sampling was used. First stage units where primary care physicians randomly selected at every Spanish province. Second stage units were 20 randomly selected persons drawn from every participating physician's assigned population. Finally, 8,343 consented to participate and completed the study protocol that included a 12-lead-EKG. There was centralized reading of the EKGs that were evaluated by two trained cardiologists. In case of disagreement a third cardiologist was consulted. Final diagnosis was reached by consensus. We analyzed the prevalence and related factors of different EKG findings: QT abnormalities, cavities enlargement, conduction disorders, repolarization abnormalities, pathological Q waves, atrial and ventricular premature beats and pre-excitation.
Results: Mean age was 59.2 years, 52.4 % female. Only 4,074 participants had an strictly normal EKG. (Weighted prevalence 51.2%). Abnormalities most frequently found are shown in Table 1.
Conclusions: EKG abnormalities are very common in the general population older than 40 years in Spain (Southern Europe). Only about half of the population had a completely normal EKG
