I am impressed! I received a thorough review of 3 ECGs and the technician was so helpful and friendly in their reporting. I've felt more "heard" by this app's technician than in all the time I spent with other doctors. I will be following up with my doctor, though, and I greatly appreciate this app!

With the modern availability of at-home devices that can measure ECGs, it is now challenging for cardiologists to keep up with all of these readings. On Qaly, trained ECG technicians read every ECG you submit.  If you want to learn what your ECG may be telling you, this is the place to start.

I looked for an app that uses real technicians, and not an algorithm to read my ECGs. Luckily, Qaly was there at the right time for me.
