Being the spouse of a cardiac patient, I have experienced many a sleepless night over the years when my husband was nervous in the middle of the night for one reason or another as a result of not feeling well. Specifically if he felt his heart was beating funny, blood pressure was a little higher than his normal low BP, etc. Of course we have had our times of calling 911 or a ride to the ER, and we will continue to do that. However, as these incidents continued to arise, admittedly it was getting a little tough on both of our nerves as well as adding to sleep deprivation. We were recommended the Kardia Mobile App which has greatly helped ease my husband's non-serious (but serious to him) concerns. We purchased it off Amazon, and you can record unlimited EKGs. It also detects AFib, Bradycardia, and Tachycardia. It is FDA-cleared, clinically approved, and gives medical-grade EKG recordings per the website. We downloaded the app on our smartphones and there is a small, lightweight device that you simply push your fingers on next to your phone and the results show up in less than a minute on your smartphone.
