December 2016: This article has been update: Go directlly to: Sleep Apnea: Home Testing with WatchPAT Device and the Philips Respironics
At least 49% of all patients with A-Fib suffer from Sleep Apnea as well. With untreated Sleep Apnea, you have a greater chance of a more severe form of A-Fib and increased risk of recurrence after a successful catheter ablation.
Everyone with A-Fib should be tested for sleep apnea. Traditionally this has involved an overnight stay in the sleep lab.
But now there’s an alternative! You can test at home with the WatchPAT™ device.
The WatchPAT™ is an FDA-approved wrist-worn sleep study device you can use in the comfort of your own bedroom to determine if you have sleep apnea. (PAT is short for Peripheral Arterial Tonometry [pressure measurement].)
Multiple studies have shown there is a high correlation of the WatchPAT with sleep indexes such as the respiratory disturbance index (RDI) and the apnea-hypopnea index (AHI), compared with the same indexes measured by the normal sleep test PSG.
If you think you may have untreated Sleep Apnea: read my full review.
