Precise Heart Rate Measurement?
… actually measuring the heart rate in the veins or blood vessels?
The heart works to pump blood. Calculating the frequency of the heart rate or heart rate is one step of a physical examination done to assess a person's vital signs. The normal adult heart rate is around 60-100x / minute. Some experts assume that the normal heart rate is around 50-70x / minute. In special conditions, the heart rate can be slower or faster and still within normal limits, for example athletes generally have a slower heart rate, while pregnant women and babies can have a faster heart rate.
This heart rate is measured when the patient is calm and relaxed. Counting the heart rate is the same as counting the pulse. To calculate the pulse can be done by looking for arteries, for example in the wrist, neck, or groin.
Coming back to your question, the pulse is one of the blood vessels. Blood vessels in general, there are arteries and veins. arterial blood vessels carry blood around the body from the heart. Meanwhile, the veins will carry deoxygenated blood from the body to the heart. Arterial blood vessels are another name for nadi. Thus, to measure the heart rate is done on the arteries or pulse.
