Background:
Age-specific differences in the association between sleep duration and atrial fibrillation (AF) remain uncertain.
Methods And Results:
Using the estimated sleep duration derived from accelerometer data embedded in the Holter-electrocardiogram, association between sleep duration and AF was explored among individuals in their 50 s (working-age) and 70s (retirement-age). In the overall population, AF risk decreased with longer sleep, but the benefit diminished with excessively long sleep (P=0.03). Also, consistent risk reduction with increasing sleep was observed in the 50s age group (P=0.02), but not in the 70s.
Conclusions:
Inadequate sleep may be associated with AF, particularly, among middle-aged individuals.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
