What does a heartbeat around 85 mean?

A heartbeat of 85 beats/min means that the heart rate of the body is normal.

Healthy people at rest, the number of heartbeats is generally 60-100 beats/min, and the heartbeat is about 85 beats/min in the above range, so it is a normal phenomenon, no special treatment is required. If the body at rest heartbeat is less than 60 beats/min, it is generally bradycardia, which may be related to hypothyroidism, myocarditis and other reasons. If the heart beats more than 100 beats per minute, it is considered tachycardia, which is related to emotional agitation, exercise, hyperthyroidism and other reasons.
