PULSE
Posted on 12:30 AM by know about heart
Pulse: It can be explain as the expansion and elongation of arterial wall that is produced by the pressure changes during systole and diastole of ventricle. Pulse reflects the condition of the heart.
Some points to be noted during examination of pulse:
1) Rate: It means to frequency of pulse per minute it corresponds to heart rate.
2) Rhythm: It indicates whether the beats are equidistant or not.
3) Volume: It means rise of the pulse wave above the diastolic level volume is decrease in M. contractility.
4) Character:
5) Condition of arterial wall
6) Symmetry: It is normally symmetrical in either side.
7) Radio-female delay: Normally there is no delay. Delay occurs in coarction of aorta.
Site of examination of pulse: Usually we examine the pulse in different artery, such as_
1) Radial
2) Brachial
3) Axillary
4) Femoral
5) Popliteal artery etc.
Normal pulse: Normal pulse is found in normal condition in different arteries, such as redial, brachial, carotid, femoral, political, pulse of anterior tibial, posterior tibial arteries and that of arteria dorsalis pedis, normal pulse is called catacrotic pulse.
Abnormal pulse:
A)Low volume pulse (weak pulse): A weak pulse at the redial artery generally indicated that the quantity of blood ejected by the left ventricle to the arteries with each beat is less than normal. It occurs in 1) heart failure, 2) Dehydration, 3) Peripheral vascular disease, 4) Hemorrhage, 5) Coarction of the aorta.
B)High volume pulse (strong pulse): It occurs in some disease-
(1) Aortic regurgitation
(2) fever,
(3) anaemia,
(4) thyrotoxicosis,
(5) Peripheral arteriovenous shunts
(6) Paget’s disease of bone.
How to measure pulse:
We can know important information about our health by measuring the pulse. For example, fast pulse may signal an infarction in the heart. Usually redial pulse are measured, because it is very easy to measure redial pulse. First, we place index finger with second and third finger at the wrist joint below the base of the thumb. Then create slight pressure by index and second finger and fell redial pulse by third finger. Normal count is 60 to 90 beat/minute in an adult person.
In some normal condition pulse rate increase such as
1) During sex
2) Exercise
3) Time of eating
4) Emotion etc.
