Resting heart rate 84. Is that normal?

A resting heart rate of 84 beats/min is normal.

Heart rate can reflect the basic life state of the human body. Adults in a quiet, awake state, heart rate in the 60-100 beats/min is a normal range. Therefore, for people with a resting heart rate of 84 beats/min, their heart rate is normal. If an adult in a quiet, awake state, heart rate exceeds 100 beats/min, it belongs to tachycardia. The causes are considered to be related to excessive exercise, alcohol, emotional factors, arrhythmia, etc. If the adult is quiet and awake, the heart rate is lower than 60 beats/min, it belongs to bradycardia, and the cause is considered to be related to long-term exercise, arrhythmia, heart failure, etc.
