What type of motion is heartbeat?

Heartbeat is a type of periodic motion.
The heartbeat can be classified into two main types of motion, depending on how you look at it:

1. Periodic motion: When viewed from the perspective of time, the heartbeat is a periodic motion. This means that it repeats itself at regular intervals, with each cycle consisting of a contraction (systole) of the heart chambers followed by a relaxation (diastole). The time period of a heartbeat is the interval between successive contractions, and it's typically measured in seconds or beats per minute (bpm). A normal resting heart rate for adults is usually between 60 and 100 bpm.

2. Oscillatory motion: If we focus on the individual chambers of the heart, their movement during a heartbeat can be considered an oscillatory motion. This is because the chambers expand and contract rhythmically, like a spring or a pendulum swinging back and forth. However, it's important to note that this oscillatory motion is not perfectly sinusoidal, as the contraction phase is typically faster and stronger than the relaxation phase.

Therefore, the characterization of the heartbeat's motion depends on the specific aspect you're interested in. Overall, it exhibits both periodic and oscillatory characteristics, contributing to the efficient circulation of blood throughout the body.
