Impressive

My cardiologist was interested in more long term monitoring for me, but I did not want to wear a device for 30 days. I do not have any serious issues according to all the tests, but she was interested in capturing my PVCs when they happened and told me about the KardiaMobile devices. I chose the card because it is easy for me to carry it with me and I have already used it several times. A brilliant little device.

Grateful

I'm so grateful for Kardia products. It alerted me to the start of Afib episodes. This led me to my doctor and treatment.

KardiaMobile card

I just purchased a KardiaMobile card and love it. It's so easy to use and helpful to check my heart with EKG's to determine if I'm in AFIB. I also love that it's the size of a credit card so that I can easily keep it in my wallet
