Heart rate 220 on an adult - what does it mean?
A resting heart rate of 220 bpm is very high — above the estimated maximum heart rate for adults (220 minus age, about 200 bpm at age 20). At rest, a pulse this fast needs urgent medical attention.

What a resting pulse of 220 means
At rest, a sudden racing heartbeat of 220 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.
Ranges apply to adults and children aged 10 and older, measured at rest (American Heart Association). By the numbers: at 220 bpm the heart beats about every 0.27 seconds — roughly 316,800 beats a day.
220 bpm during exercise
During exercise a higher pulse is expected. This table shows which training zone 220 bpm corresponds to, based on the common estimate of maximum heart rate (220 minus age). Individual maximums can differ by 10–20 bpm.
220 bpm is above the estimated maximum heart rate at every age in the table. Individual maximums can be 10–20 bpm above the estimate, so a young person may reach it during all-out effort — but not at rest.
| Age | Est. max (220 − age) | 220 bpm is | Training zone |
|---|---|---|---|
| 20 | 200 bpm | 110% of max | above estimated max |
| 30 | 190 bpm | 116% of max | above estimated max |
| 40 | 180 bpm | 122% of max | above estimated max |
| 50 | 170 bpm | 129% of max | above estimated max |
| 60 | 160 bpm | 138% of max | above estimated max |
| 70 | 150 bpm | 147% 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.
