Doctor recommended
Dr. Douglas S, M.D., KardiaMobile User Five star rating

I have used the AliveCor monitor regularly for the past 2 years and have been recommending it to my patients with cardiovascular symptoms (particularly atrial fibrillation). I could not be happier with the product.

Great investment
Steve P, KardiaMobile User Five star rating

Kardia has been a great tool for me to learn/verify my symptoms, and to share real world data with my EP

AliveCor Helped Save My Life
J Aleck, KardiaMobile User Five star rating

I can't say enough about the AliveCor. It has already saved my wife's life and mine

Peace of Mind!
Scott, KardiaMobile User Four and a half star rating

Several times when I was in atrial fibrillation, I was able to talk with my doctor by phone and adjust medication and avoid a trip to the ER. As they say, knowledge is power; in my case, knowledge leads to peace of mind.
