In general, it is easiest to detect a pulse at the wrist (radial pulse), neck (carotid pulse), bend in the arm (brachial pulse) and at the groin (femoral pulse). A strong pulse detected in the abdomen may suggest the presence of an aneurysm. When peripheral pulses are not detectable, such as pulses at the wrists or ankles, vascular disease may be inhibiting proper blood flow.
The radial pulse (at the wrist) is most easily accessible, and is often the first pulse used to gauge heart rate and rhythm. If the radial pulse is faint or absent, a more central pulse, such as a carotid or femoral pulse, may be used.
A pulse should be felt with the tips of the index and middle fingers, as these fingertips are highly sensitive. You should not press too hard as this may stop blood flow and the pulse itself. Do not use your thumb as it has its own pulse. When feeling a pulse, noting the rate, rhythm and character can provide improtant information.
A doctor will usually take a history, perform necessary examinations and investigations for each condition. Pulse examination is a very useful tool which can reveal a lot regarding heart function and vascular health. Rate, rhythm and character are the main aspects assessed with a pulse. Combined with other observations and tests such as an ECG for example, more reliable conclusions can be drawn about your health. Your doctor will take this into account during a visit to suggest the next best steps for you.
