Question

The sensitivity of an electrocardiograph is typically set at 10 mm/mV.

(a) True

(b) False

I have been asked this question in a job interview.

My question comes from Electrocardiography in section Biomedical Recorders of Biomedical Instrumentation

Answer 1

Correct answer is (a) True

The best I can explain: It is true. The sensitivity of an electrocardiograph is typically set at 10 mm/mV. For routine work, the paper recording speed is 25 mm/s. Amplitude measurements are made vertically in millivolts. Time measurements and heart rate measurements are made horizontally on the electrocardiogram.
