Hi. Some nights I keep waking up with a racing heart every few minutes for some portions of the night, especially closer to the morning. During these episodes I don’t particularly feel out of breath, though I do take one deep breath when I suddenly wake up. Sometimes I wake up with a full body twitch and my vision is grainy.
I’ve been wondering if I have central sleep apnea, but because of the lockdowns and long wait lists for sleep studies, it will take me a long time before I get a sleep study.
I was wondering if there is an iphone app using the iphone microphone that can detect breathing (or lack of) during sleep? Thanks.
