Does the Apple Watch 7 series give a true ECG reading? I have A-fIb

Apple specifically states that it can't detect those things:

The ECG app cannot detect a heart attack. If you ever experience chest pain, pressure, tightness, or what you think is a heart attack, call emergency services immediately. 

The ECG app cannot detect blood clots or a stroke.

The ECG app cannot detect other heart-related conditions. These include high blood pressure, congestive heart failure, high cholesterol, or other forms of arrhythmia. 

It is a single lead ECG. That is not going to be a accurate as the multi-lead ECG you get in a hospital or doctor's office. But it does claim it can detect A-Fib.

I would suggest you review the article linked to above with your cardiologist. While the Apple Watch's ECG is accurate for what it is, you'll want a medical professional to tell you if it's good enough to monitor your specific condition.

I cannot tell you if it is worth having from a medical standpoint.

But for me, I would rush to replace it if it was lost, stolen, or stopped working.

I occasionally use it to tell time (or the date)

Weather on my wrist, look at several times a day. I like the MyRadar app, because it gives me a radar image.

MyQ app that works with my garage door opener, so I can open and close the gatage door when taking a walk.

ALL my iPhone alarms, alerts, notifications, reminders, etc… show up on my wrist.

I use the iPhone “Alarmed” app as my primary alarm, todo list, reminder. It is very flexible and the nag-me feature for taking my meds morning and night showing up on my wrist, is invaluable.

phone calls show up on my wrist, and if it is SPAM call, I can just press the Digital Crown and silence it. Or answer non-spam and talk via my wrist. Very convenient.

In the kitchen, is an often saying into my Apple Watch “Hey Siri, 2 and a half minutes” to start a timer.

On walks or bike rides, I often think of something, so I’ll say to my Apple Watch “Hey Siri, remind me when I get home to mumble, mumble that idea” and a reminder will be set that will not go off until I get home.

I have the Apple Watch remind me to wash my hands when I get home (it is a setting).

And I have my Apple Watch automatically time my hand washing. It hears the running water and notices my hand motion when washing, the starts a 20 second timer.

I do use it to track my exercise, but I’m not anal about it.

Because my Wife has an Apple Watch, I can actually message her. Before, her iPhone was always in the kitchen or buried in here purse, and she would never know I messaged her. With the Apple Watch, that is no longer a problem. This works in the house as well as when we are in different locations, as it is better that yelling and not being understood because of echos and closed doors. Things like “ your dryer is finished”, or “do you want to go for a walk”, etc…. All low priority stuff, that does not need to interrupt them if they are really busy.

When listening to music via my iPhone, the Apple Watch can control the volume and skip songs. Same for podcasts.

I did not know I would love having the Apple Watch so much until I had it for a few weeks. I had my Series 4 for 3+ years, and I so happy we got them.

My Wife has a cellular, and a have a GPS only, but they do the same things, except I just have to keep my iPhone nearby.
