heart rate change
Cardiac tempo variation
Heart rate change is a shift in how fast the heart beats, whether an increase or decrease from a baseline.
The phrase appears in medical and fitness contexts where tracking such fluctuations matters: The monitor detected a sudden heart rate change during the stress test.
Heart rate variability is a related but distinct concept measuring beat-to-beat timing differences.
