Heart rate 167 on an adult - what does it mean?

167bpm

Very high

A resting heart rate of 167 bpm is very high. During hard exercise it can be expected (see the training table below) — at rest, a pulse this fast needs urgent medical attention.

What a resting pulse of 167 means

At rest, a sudden racing heartbeat of 167 bpm is usually not ordinary sinus rhythm. Typical causes are supraventricular tachycardia (SVT), atrial flutter or fibrillation, and — less often but more dangerous — ventricular tachycardia.

Also double-check the reading: wrist devices can lock onto your movement cadence during exercise and report it as heart rate.

What to do: If this is a resting reading, seek urgent medical care now — call 911 (US) or your local emergency number if you have chest pain, shortness of breath, dizziness or feel faint.

Ranges apply to adults and children aged 10 and older, measured at rest (American Heart Association). By the numbers: at 167 bpm the heart beats about every 0.36 seconds — roughly 240,480 beats a day.

167 bpm during exercise

During exercise a higher pulse is expected. This table shows which training zone 167 bpm corresponds to, based on the common estimate of maximum heart rate (220 minus age). Individual maximums can differ by 10–20 bpm.

Age	Est. max (220 − age)	167 bpm is	Training zone
20	200 bpm	84% of max	Zone 4 · Hard
30	190 bpm	88% of max	Zone 4 · Hard
40	180 bpm	93% of max	Zone 5 · Maximum
50	170 bpm	98% of max	Zone 5 · Maximum
60	160 bpm	104% of max	above estimated max
70	150 bpm	111% of max	above estimated max

This page explains a single reading in general terms. It is not a diagnosis. Heart rate alone cannot tell whether the rhythm is regular or whether the heart is healthy — if you are worried, talk to a doctor.
