Because of Qaly, I went to my doctor and was diagnosed with SVT and was told it was probably never an anxiety disorder. I have lived 15 years of hell thinking I was having intermittent panic attacks and agoraphobia. Getting set up for an ablation. I will be forever grateful.” — Marcie D. from Alabama “Qaly was so helpful in quickly identifying signs of a potentially serious heart condition … Without Qaly, I would have blown off the ECG and maybe shown it to my primary care doctor at my next appointment a few months away.” — Lori B. from Virginia “My Apple Watch categorizes my arrhythmia as normal or inconclusive, which makes me question what I’m feeling. Without Qaly, it would’ve taken me another 6 months to a year to take this to a doctor. With Qaly I gained valuable information. Qaly is the key.” — Jessi I. from Washington ----- Qaly members get peace of mind: • ECG analyzer for all watches and devices: Apple Watch ECG, Fitbit ECG, Kardia ECG, Wellue ECG, Withings ECG, WHOOP ECG, Garmin ECG, holter monitors, and more. • Borderline ECG, Inconclusive Apple Watch ECG, Inconclusive Fitbit ECG, Unclassified KardiaMobile EKG, WHOOP ECG, Garmin ECG, and all other Inconclusive ECGs analyzed within minutes, for clarity. • See irregular heartbeats like PAC and PVC on your ECG, analyzed by an expert ECG reader. • See your PR Interval, QRS Interval, and QTc Interval on your ECG, also analyzed by an expert EKG reader. • Get more from Qaly technician interpretations than your typical ECG analyzer app or HRV tracker: Qaly is the only ECG interpretation app where human experts provide professional analysis of your heart readings within minutes. • Share Qaly reports with your doctor, cardiologist, or electrophysiologist. ---- The Qaly app displays ECG data by integrating with the Health app. This is not available on the iPad.
