How does ECG work on Garmin work? Simple, fast, but limited
- Two electrodes: one on the case, the other on the crown. We put the other hand, the watch measures the electrical signal of the heart.
- 30 seconds: that’s all it takes to get a route, directly on the watch and in Garmin Connect.
- Automatic analysis: The watch detects atrial fibrillation (FA) or a normal sinus rhythm. Nothing more, nothing less.
- PDF report: to share with your doctor, if necessary.
Major limit: Unable to detect other disorders (infarction, extrasystoles, etc.). The Garmin ECG is the Sentinel de la Fa, Point Barre.
What Garmin watch takes blood pressure?
Let’s be clear: No garmin watch measures blood pressure in 2025. Neither the fenix, nor the coming, nor any other. Confusion often comes from the term “health monitoring”: Garmin measures heart rate, oxygen saturation, but not blood pressure. For this, you need a dedicated medical blood pressure monitor. If tension is your priority, go your way or turn to other brands like Huawei or Samsung, which offer this function (with reserves on reliability).
Is ECG watch useful for atrial fibrillation?
Yes, and it’s even only validated medical utility ECG on Garmin.
Atrial fibrillation (FA) is a frequent disorder, responsible for 20 to 30 % of strokes. The Garmin ECG allows it to detect it, even outside the symptoms, and to quickly alert your doctor.
- This is not a diagnosis, but an alert tool.
- In case of doubt or symptoms, only a health professional can decide.
- The ECG does not detect infarction, tachycardies or other anomalies.
In summary: For the FA, the ECG Garmin is a real plus, especially for people at risk or anxious. For the rest, it does not replace a medical electrocardiogram or a classic cardiological monitoring.

My clear opinion:
Pure sportsman: Fenix 8, the most complete.
Ultra-enduring: Enduro 3, unbeatable on autonomy.
Urban/health use: coming 3, discreet and efficient.
Garmin ECG: gadget or revolution?
Let’s be frank: the ECG on Garmin is not a revolution for the sportsman, but a real plus for the health monitoring of everyday life.
- For whom? Those who want to monitor their hearts without stress, share a relationship with their doctor, or who have a history of FA.
- For what ? Detect atrial fibrillation, and nothing else.
But…
If you are looking for complete medical follow -up, go your way.
If you want blood pressure, look elsewhere.
If you like simplicity, the Garmin ECG does the job, without frills.
My personal experience (and that of my clients)
After testing the Fenix 8 and the coming 3 over several weeks, I remember:
- Simplicity: Quick activation, readable result, easy sharing.
- Reliability: clinically validated, results consistent with medical devices.
- Limits: no in -depth analysis, no continuous detection, no tension.
My clients, often anxious after 50 years, appreciate peace of mind. But none have happened a real medical follow -up after an alert.
Conclusion: ECG Garmin, a real asset … but not for everyone
The Garmin ECG is the discreet ally of those who want to keep an eye on their hearts, without falling into paranoia.
For atrial fibrillation: Useful, validated, reassuring.
For tension, infarction or sports analysis: Go your way.
My advice?
Choose your Garmin watch with ECG according to your real needs, not in fashion. And always keep in mind: technology never replaces the advice of a professional.
