For 15 years, I lived my life thinking I had an anxiety disorder. I sent one of my ECGs to the QALY app, and I was really surprised the review said it looked like SVT. So, I took it to my cardiologist, and he said that I should get an ablation. If it wasn’t for this app, I would still believe that I had an anxiety disorder.


Read Marcie's story

I’ve been diagnosed with Afib, SVT, and PACs. I have a Kardia, and sending those strips to the doctor can take three or four days to hear back. So the fact that I could submit them to QALY, and a technician could get back to me a lot sooner was a sigh of relief.


Read Tenicia's story

It wasn’t until my first ECG review with QALY that I was able to catch some dysrhythmias. QALY gave me a whole breakdown on what they were. It’s been an amazing tool — almost like a piece of security or peace of mind.


Read Anna's story

QALY has taken the mystery out of reading my ECG strips. It has made me less anxious, and I’m not so fearful anymore. What I love about this app is that I can download the reviews and send them to my doctors — which I’ve done — and they’ve been very impressed with QALY technician reports.


Read Judy's story

QALY gives me peace of mind — to just have the knowledge that I can send in an ECG if I’m uncertain, and get an understanding of what’s going on with my heart.

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.

Best subscription I have ever paid fo
By LucieGoodwin

I have paid for the premium service for the past month and I do not regret paying a single penny. The technicians are extremely down to earth, polite, sympathetic and reassuring when it comes to reviewing an ECG. I have always had my ECG a review back extremely quick and had a detailed description of the findings. Big thanks to Mary-Ann, Franz, Gladys and Peter John M. who have all been so kind when reviewing my ECG’s. Thanks! Lucie G

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!


Thank you to my @qalyheart technician ♥️ for always giving me and others a piece of mind. The ECG readings helps keep me out of the ER for POTs.

Amazing response time!

Very impressive app! It’s like I have a doctor traveling with me always!

The ECG feature, paired with the @qalyheart app, is also fantastic. Super eager for this portion of the tech to advance.

Life changing and anxiety reducing

This app is a God send. It calms my anxiety and literally helped me sleep the night after my first review. It is reassuring and QUICK. I highly recommend it. THANK YOU!!!

Surprisingly helpful app!
by L0G4N

Hi everyone, I rarely if ever leave app reviews but I felt the need to briefly comment on this app. I’ve been undergoing quite a bit of cardiology monitoring post COVID-19 infection and have found it helpful to capture an ECG reading on my Apple Watch when I’m having heart/chest issues. The Apple Watch health app is great but lacks detail. This is where I’ve found huge value in the QALY app! It provides immediate detail not found in the health app and then the true game changer.. technician review of your reading that givens ever more clarity around your data. While I know this app isn’t providing medical advice and you should seek professional medical care in an emergency, this app has helped provide me peace of mind and additional data to bring my cardiologist. Thanks, QALY.

Thank you to my @qalyheart technician! I'd really recommend you to download this app if you have an apple watch and feeling mild heart discomfort, the results for me came in within 10 min.  Thanks Louie for the help!👍

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.
