The standard English idiom for measuring a person’s heartbeat is “to take someone’s pulse”. Therefore, “The doctor took my pulse” is the most natural and correct sentence.

১. While a doctor might ‘examine’ a patient, they specifically ‘take’ the pulse.
২. ‘Saw’ and ‘found’ are semantically incorrect in the context of clinical pulse measurement.
৩. Correct collocations are essential for natural-sounding English in professional contexts.
