The pulse is a pressure wave caused by the expansion and recoil of elastic arteries after each systole. It is a vital sign providing insights into the heart rhythm and rate. The rhythm pertains to the regularity of the beats, while the rate refers to the number of beats per minute. A normal resting pulse for healthy adults ranges from 60 to 100 beats per minute. A weak or irregular pulse may signal circulation problems or potential health issues. For instance, in tachycardia, the resting pulse is abnormally fast, over 100 beats per minute. It may indicate shock, dehydration, or heart failure. On the contrary, an abnormally slow resting pulse below 60 beats per minute can indicate bradycardia. It can be a sign of aging, hypothyroidism, or cardiovascular problems. Pulse is commonly measured by palpating the radial artery on the wrist. It can also be measured at different points, such as the superficial temporal artery near the ear, the carotid artery near the larynx, or the brachial artery near the elbow.
