How to measure heart rate

There are several ways to measure heart rate. For normal people, the heart rate can be measured by counting the pulse, that is, pressing the artery at the wrist to see the pulse and counting 1min. At this point, the calculated value is the heart rate. Another method is to use an electronic sphygmomanometer. On the one hand, blood pressure can be measured, and at the same time, the heart rate can be displayed.

Counting the pulse or the heart rate displayed on the electronic sphygmomanometer cannot completely replace the actual heart rate. For example, if there is atrial fibrillation or premature beats, there will be errors in heart rate measurement. To accurately measure the heart rate, you should find a professional doctor to listen to the heart, or do an electrocardiogram to determine what the heart rate is. To observe the overall situation of heart rate, we can do it through 24-hour dynamic electrocardiogram.

Precautions:

1. Pulse measurement position: All superficial arteries close to bones can measure pulse. Radial artery (wrist thumb side) is the most commonly used, followed by temporal artery, carotid artery, brachial artery and dorsal foot artery.

2. Pulse measurement (taking the radial artery as an example): the examinee takes a comfortable lying position, and the examiner presses the fingertips of the index finger, middle finger and ring finger on the radial artery inside the examinee's wrist, and the finger pressure should be able to clearly feel the pulse. Generally, the normal pulse is measured for half a minute, and then multiplied by 2 is the number of pulses per minute. Abnormal pulse should be measured for at least one minute. If the pulse is weak and unclear, you can listen to the heart rate count with a stethoscope.

3. Normal pulse value: the pulse rate of normal adults in a quiet state is 60 ~ 100 times per minute, and that of the elderly is 55 ~ 60 times per minute; Children about 90 times per minute; Newborns can reach 140 beats per minute, and the pulse should be even, regular and strong.
