The prevalence of atrial fibrillation (AF) in general and asymptomatic AF in particular in Chinese population is unknown. Data on the use of a smartphone-based wireless single-lead electrocardiogram (AliveCor Heart Monitor, AliveCor Inc, CA, USA) for community screening of AF is scarce.
Wireless single-lead ECG using AliveCor Heart Monitor (AHM) will be performed in an unselected voluntary adult Chinese population of 10,000 citizens in Hong Kong in one year. This is an interim report on 2001 citizens (1365 [68%] female, mean age 65.1±13.7).
Thirty-six (1.8%) citizens were diagnosed with AF. The prevalence of AF was higher in male (3.8%) than in female (0.9%) and increased progressively with age (%lt;60 [0.2%]; 60-69 [1.4%]; 70-79 [2.9%]; ≥80 [4.2%]). Twenty-four (66%) of them had no prior history of AF and 22 (61.1%) were asymptomatic. Thirty-four (94.4%) of them had CHA2DS2VASc score ≥ 1 and warranted anticoagulation treatment.
The prevalence of AF in Chinese population appears to be comparable to the Western counterparts except an apparently higher male preponderance. There is a high proportion of Chinese patients with asymptomatic AF. Community screening for AF with AHM is feasible and capable of identifying citizens with AF and high risk of stroke.
