ECG functionality

Best

#1
Apple Watch Series 11
Reviews consistently note ECG support and explicitly mention that the watch can perform ECG checks.
#2
Garmin Vivoactive 5
ECG is not available, and multiple reviews explicitly say the hardware does not support it.
#3
Apple Watch SE 3
ECG functionality is absent on the SE 3, and several reviews frame that missing feature as one of the main reasons to consider a more expensive model.
