BACKGROUND AND AIMS:
ECG abnormalities are often found in older patients but relatively few epidemiological studies have been performed. This app provides over 170 abnormal ECG cases recorded from elderly population over 80 years old, to illustrate the knowledge of how to identify ECG problems for senior people.
POTENTIAL RESULTS:
After study all cases in the app, the potential results are: in both sexes, the prevalence of ECG abnormalities was significantly lower in the later-born cohorts. From age 70 to 95, there was an increase in both men and women of large or intermediate Q-waves, left axis deviation, negative T-waves (0-5 mm), complete right bundle branch block (RBBB), and atrial fibrillation or flutter. Compared with those with no ECG abnormalities, the mortality risk was higher among individuals with large and intermediate Q-waves and negative T-waves (> or = 1 mm) in both sexes, and STJ depression > or = 0.5 mm and complete LBBB together with complete RBBB and intraventricular block; QRS > or = 0.12 sec in men only.
