What is Heart Rate?

Heart Rate (HR), also known as pulse, is the number of times a person's heartbeats per minute. [1]

A normal person's resting heart rate is typically 50-90 BPM. [2]

In some real-life scenarios, the heart rate is calculated over a much shorter period of time in order to obtain real-time heart rate changes. [3]

📌 Note

PPG (photoplethysmography) sensors on the Flowtime headband use light-based technology to acquire the heart rate, which is accurate when they have good contact with the skin.
