Electrocardiogram incoming ?

Hi, 

I have a Garmin Fenix 7 Sapphire Solar that I love. It's really a great watch.

But these months I'm experiencing heart problems such as tachycardia. I need to watch my heartbeat. I saw a few months ago that Garmin started deploying the ECG on the most recent models.

Do you know if the Fenix 7 Sapphire Solar has the hardware necessary to support this function ? And if Garmin plans to deploy the ECG on this specific model ?

If not I'll have to buy another one with this function and tbh, these watches are not cheap so if I Could just wait... 

Thanks a lot for your help and have a good evening
