What examiners said
The use of a stethoscope that monitors the sound of heart valves closing, and the measurement a person’s pulse were the most common correct answers. Many candidates chose one of these methods. Less successful candidates stated methods that were provided in the question, for example ECG, heart monitor and cardiogram.

Most candidates successfully read the two heart rates from the graph and calculated the increase in heart rate. Only a few candidates performed the percentage increase calculation correctly. To gain full credit for this calculation, candidates had to find the change of heart rate as a fraction of the original heart rate and multiply this by 100. So, the calculation would be 90 ÷ 60 × 100 = 150%. V...
— Examiner report, May/June 2025, 0653/32 Q1(c) (Cambridge)
This was often answered correctly. Candidates needed to make it clear that the heart rate increased after two minutes rather than simply stating that it changed. Some candidates chose to describe the unchanging heart rate before the two-minute point but, on its own, this did not gain credit.
