I have an old Apple Watch Series 5 and a newer Series 8. The Series 5 is connected to an iPhone SE and the Series 8 is connected to an iPhone 12.

The Lookee Tech ECG device downloads the ECG data to the VI Health app (screen shot attached) on my iphone through bluetooth. The ECG device alone has limited storage capacity. Once I take a few readings, I select the Settings button and then Bluetooth to transfer the ECG to my iPhone "VI Health" app. Then I delete the ECGs on the device.

The iPhone Health app complies data from the Watch, Activity, and other devices, such as the Omron Connect Series 5 Wrist Blood Pressure Monitor, or Lookee Tech Sleep Pro Oximeter (oxygen level) . My phone keeps all my readings historically and graphs them.

Heart rhythm conditions can be challenging to diagnosis and treat. I have relied on my EP's nurses and physician assistants to help me learn more about my specific heart rhythm issues and treatment options. Are you able to message your Cardiologist or EP through their electronic medical record? If so, try to send a message with your questions and attach the ECG. I always get an answer same day or within a few days. The clinics can get busy. Sending a message may help you get the information you need.
