Because of the recent health crisis, my latest cardiologist appointment was done virtually rather than in office. This meant that the usual EKG was not administered. This led me to thinking of a home device that allowed me to share results with my doctor. I investigated several products before purchasing a SonoHealth EKGraph. I chose the EKGraph over the Kardia device for two very important reasons. Number one, the EKGraph provides a more comprehensive result and number two, there is no subscription to purchase. I must say the easy setup, free phone app and simplistic operation were totally hassle free. And I’m pretty tech challenged! Both my cardiologist and I are very satisfied! Thank You SonoHealth!!!
