Smart Health Watch

BP doctor watch is good at monitoring the heart rate.

Note, if you think you have a heart problem, please seek medical attention in time. If you're just interested, wearables that monitor your heart rate can help you get the most out of your workout.

By monitoring your heart rate, you can push yourself to the limit during high-intensity workouts, and make sure you get enough rest to recover after exercising.

In the long run, keeping a close eye on your heart rate can help you discover what's making your heart beat faster: exercise, stress, anger, and a lot more about cardiovascular health.

Wearables that can track heart rate can also improve the accuracy of other health data, such as sleep, calorie burn, stress levels, and VO2 max (estimating the maximum amount of oxygen used during exercise). That's not to say that a wearable device with accurate heart rate monitoring will also be accurate in tracking other data.
