Answer:
high
Step-by-step explanation:
Heart rate recovery (HRR) is the difference in heart rate in peak effort and measured over a fixed period (usually one minute) after cessation of physical activity. Low HRR values have been considered a marker of poor prognosis, as they are associated with an increase in mortality.
In small previous studies it has been seen that cardiac rehabilitation can increase the value of HRR, although it is not known if this improvement can affect mortality.
