I.H.B.
The I.H.B. ( Irregular Heartbeat ) symbol appears when
the recorder detects an irregular heartbeat that differs ±15 %
from the average pulse rate.
The principal factors of appearance for the I.H.B. symbol are
physiological factors along with heart, disease and other factors.
Examples include body motion, an increase in body temperature,
aging, physiological properties and emotional changes.
The symbol may show when a very slight vibration like trembling
or shaking is detected.
