Now smartwatches are not for just heart rate tracking or calorie tracking. Today’s health watches and fitness trackers can track complex health metrics(vital signs) such as ECG, Blood pressure, ECG, and much more.
Fortunately, most of these devices are clinically validated for their accuracy and effectiveness.
To help you choose the right health watches, I have compiled a list of health tracking smartwatches to track two or more health metrics, such as
- Heart Rate: Some watches in this list even alert you in case of an irregular heart rate.
- Electro Cardiogram(ECG/EKG): Take an ECG right from your wrist and alert you in case of irregular heart rythem such as atrial fibrillation. It can share your ECG report with your doctor as a PDF document
- Blood Oxygen Level Monitoring: Most of the health tracking watches discussed here comes with a blood oxygen sensor to track SpO2
- Blood Pressure: This list of best health tracking smartwatches also includes health watch for blood pressure monitoring
- Calories burned and much more
Even though you cannot find a smartwatch combined with all these features, everyone can find one that best suit your needs.
