BACKGROUND: Clinical presentation of atrial fibrillation (AF) is usually represented by palpitations; nevertheless, atypical presentation of AF with symptoms other than palpitations may be not uncommon in elderly patients. This study therefore aimed to evaluate incremental diagnostic value of tele-medicine at-home assessment in patients who called emergency medical service (EMS).
METHODS: A total of 27,841 consecutive EMS patients referred for suspected heart disease underwent ECG assessment with a mobile ECG-recorder device. ECGs were transmitted with mobile-phone support to a tele-cardiology 'hub' active 24/7 where a cardiologist read the ECGs. Rate of prevalence of AF, age of patients, and symptoms were analysed.
RESULTS: AF was diagnosed in 11.67% of patients who underwent ECG examination. Typical symptoms were complained by 6.56% of whole patients, only 14.05% of patients with AF: rate of subjects with AF and typical symptoms significantly decreased with age (<65 years 29.58%, 65-75 years 17.06%, >75 years 10.35%, p < 0.001). Number needed to diagnose an AF with atypical presentation (number needed to treat) decreased from 45 (<65 years) to 9 (65-75 years) and 5 (>75 years) (p < 0.001). Tele-cardiology support increased the rate of at-home diagnosis of AF from two-fold (in 40-year-olds) up to four-fold (60-year-olds) and seven-fold (70-year-olds).
CONCLUSIONS: AF with symptoms other than palpitations is a common finding in elderly EMS patients. Tele-cardiology support improves the sensitivity of diagnosis of AF in elderly EMS patients and is useful in at-home identification of subjects with AF and atypical presentation.
