VERY INTERESTING: HEART MONITORS

 Hello ladies and gents this is the Viking telling you that today we are talking about 

HEART MONITORS

What are heart rate monitors?

Heart rate monitors are devices that detect and measure your heart or pulse rate. Thanks to advances in technology, these devices are small, wearable and many use sensors that are very accurate. However, while these devices are excellent for personal use, they’re no substitute for medical devices that are much more accurate.

Why do people use heart rate monitors?

Heart rate monitors are very popular features in wearable devices like smartwatches and fitness trackers. Many of these devices also connect wirelessly to smartphones and computers. That allows users easy access to review their heart rate data. Heart rate monitors see common use for the following purposes:

• Tracking heart rate during exercise.
• Monitoring stress and activity levels during the day.
• Tracking sleep quality at night.
• Monitoring your vital signs at home, especially if you have certain health conditions or concerns.

Who can use these devices?

Heart rate monitors in wearable devices are available to anyone who wants to buy one. You can buy them at many different stores and online retailers.

TEST DETAILS

How do these devices work?

Your pulse and heart rate are two different ways to track your heart’s activity. Your heart rate is how many times your heart beats per minute. Your pulse rate is how many times per minute your arteries expand because of your heart beating.

There’s usually no difference between your heart rate and your pulse rate (or the difference is very small). However, certain health conditions, medications or circumstances can make the pulse in your arms harder to detect. That can interfere with the way these devices work.

The term "heart rate monitor" refers to devices that can detect either your heart rate or your pulse rate. These devices use two different approaches:

• Electrical (electrocardiography): Your heart generates a small electrical current with every heartbeat. Heart rate monitors with electrical detection capabilities can detect and track that current.
• Optical (photoplethysmography): These devices use infrared light to see the expansion of your arteries as your heart pumps blood through them. These devices track your pulse rate, and some can also estimate the oxygen levels in your blood.
