What is sleep apnea and how can it lead to heart failure?

ANSWER

In sleep apnea, your breathing pauses over and over again while you sleep. Each time you stop breathing, your brain jolts you awake to get it restarted. It may be linked to atrial fibrillation (a quivering or irregular heartbeat) and high blood pressure in your lungs, which can lead to heart failure.
