Heart-rate recovery.
Measure how far heart rate falls during the first minute after a standardised exercise effort.
Calculate the one-minute drop.
Record peak heart rate at exercise cessation and heart rate exactly one minute later.

Why protocol matters
Walking, seated rest and supine rest do not produce interchangeable results. Compare retests only under the same conditions.
Public evidence
Cole et al. heart-rate recovery and mortality
Exercise ECG cohort study
Method and limitations.
The classic active-recovery threshold defined an abnormal response as a drop of 12 bpm or less after one minute.
This calculator does not diagnose cardiovascular disease or replace supervised exercise testing.
