Can Smartwatches Really Tell If Your Heart Is Healthy?

A smartwatch is a special watch that can count how fast your heart beats.

Some smartwatches can even record a simple heart test called an ECG and can ring an alarm if your heart beats in a strange way.

That alarm can be helpful, like a friend telling you to pay attention.

But the watch cannot tell you if your heart is completely healthy.

It cannot see inside your body to check for clogged pipes in your heart, called blocked arteries.

It also cannot check for heart problems like weak valves or high cholesterol.

Sometimes the watch rings the alarm by mistake, because moving around or the watch not touching your skin well can confuse it.

So if your watch gives a strange warning, do not panic, but do tell a doctor.

A doctor can do bigger and better tests to make sure your heart is really okay.

Your smartwatch is a helper, not a doctor.
