The word “pulse” has several common meanings:
In medicine
- Pulse usually means the heart rate, or how many times the heart beats in one minute, felt where an artery is close to the skin (for example at the wrist or neck).
- A normal resting pulse for most healthy adults is roughly 60–100 beats per minute.
In physics and engineering
- A pulse can mean a brief change in something that is usually steady, such as a short burst of electrical current, voltage, or an electromagnetic wave.
In food and agriculture
- Pulses are the edible dry seeds of legumes, such as lentils, beans, peas, and chickpeas.
If you say what context you mean (medical, physics/electronics, food, etc.), a more specific explanation can be given.
