Pulse/heart rateis the wave ofbloodin thearterycreated by contraction of theleft ventricleduring a cardiac cycle. The strength or amplitude of the pulse reflects the amount of blood ejected withmyocardialcontraction (stroke volume). Normal pulse rate range for an adult is between60-100 beats per minute. A well-trained athlete may have a resting heart rate of 40 to 60 beats per minute, according to theAmerican Heart Association(AHA).[1]See alsoheart rate
Types of Pulse rate[edit|edit source]
- Peripheral pulsesthat can be felt at the periphery of the body by palpating an artery over a bony prominence. Examples are carotid, radial andpoplitealpulses
- Apical pulseswhich is a central pulse located on the apex of the heart that is monitored using a stethoscope.[2]
Factors that Influence Heart Rate[edit|edit source]
- Age
- Sex
- Emotions/stress
- Exercise
- Medication[2]
How to Check Pulse[edit|edit source]
To measure pulse rate. Place your index and third fingers on your neck to the side of thetrachea, never press on the pulses on both sides of the lower neck at the same time to prevent blocking blood flow to the brain. To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery (which is located on the thumb side of your wrist)
When taking your pulse:
- Using the first and second fingertips, press firmly but gently on the arteries until you feel a pulse.
- When you feel pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate beats per minute.
- When counting, do not watch the clock continuously, but concentrate on the beats of the pulse.
- If unsure about your results, ask another person to count for you.
Parameters of Pulses[edit|edit source]
Rate: Number of pulsation which could beBradycardia(<60/minute) orTachycardia(>100/minute)
Rhythm: Time interval between pulse beats[2][3]
Physiotherapy Management[edit|edit source]
The role of the physiotherapist is to monitor the heart rate during exercise, the intensity and safe exercise level. The pulse rate must be taking into account to determine the level of intensity exercise the patient can bear (light vs moderate vs heavy exercise intensity zone).[4][5]
