What examiners said

The term electrocardiogram or ECG was correctly identified by some candidates. A few referred to listening to the sound of valves closing. The most common insufficient ideas seen were using a stethoscope and taking blood pressure.

— Examiner report, May/June 2025, 0654/41 Q2(c)(i) (Cambridge)

Candidates found the explanations demanding but most gained some credit. The need for more oxygen was well known but few explained why it was needed. Many stated the build-up of an oxygen debt but did not explain why. A significant number attempted to answer all three bulleted points rather than just heart rate and breathing or simply repeated the bulleted points.

— Examiner report, May/June 2025, 0654/43 Q2(a)(i) (Cambridge)

Nearly all candidates correctly calculated the difference between the resting pulse rate and the pulse rate during exercise.
