Missed By a Heartbeat

I purchased the watch to track my heart rhythm to determine if my aFib (atrial fibrilation) has been cured. The ECG function on Samsung's Heart Monitor software does not work with the Galaxy Watch3. Liam at Best Buy's Geek Squad, helped me resolve the issue by finding a Galaxy Watch7 (open box) for a lower price. It took more time than anticipated, but I got the heartcheck that I needed. Thanks!

I bought this to monitor my Afib, but the ECG software didn't work on the Watch3. Luckily, the Geek Squad helped me find an open-box Watch7 for a lower price that has the features I need. It took a while, but it worked out.
