What is a Heart Rate Histogram?
The heart rate histogram is part of the personal analysis within the KENKOU Stress Guide app. It shows the frequency of heart rate intervals within a given time (e.g. a breathing exercise or a measurement).
The highest peaks identify which heart rate intervals are the most frequent. This is not necessarily a curve like on the image below. Depending on where the most peaks are, a user’s heart rate can be classified into three different types:
- Tachycardia is widely used for a resting heart rate over 100 beats per minute in adults.
- Normocardia describes a resting heart rate between 60 and 100 beats per minute adults.
- Bradycardia stands for a slow resting heart rate under 60 beats per minute in adults.
