Instruction
1. Rhythmical blows of heart are quite well probed on a neck on the right side, there passes the large blood artery. It is rather simple to lay a hand to this place and at once easy percussions in this area are felt. It is not necessary to keep count of these blows the whole minute. It is enough to count blows within fifteen seconds and then to increase by 4. It will be exact measurement of heart rate. Also pulse is well probed on both wrists. The principle of measurement here same, as well as on a neck.
2. If houses are a tonometer, then measurement of pulse happens quicker and more precisely. But it is better to take average indications. It is necessary to measure three times pulse by the device and then to count an arithmetic average (all three indications develop and divided into three). Such measurement will be the most exact.
3. More difficult the situation with measurement of heartbeat at the child in to womb mothers is. It is impossible to probe it independently without the assistance of the expert. But doctors have special devices for this sort of measurements. Right at the beginning pregnancies take such measurements during regular planned ultrasonographies. It enters obligatory medical examination of mother and heart of their child.
4. One more inspection of a cardiac muscle at which measurements of pulse are surely taken it is an echocardiography. This inspection is appointed, as a rule, at obvious heart troubles at a fruit. At the normal course of pregnancy and development of the child in mother's belly such inspection is excessive.
