Question

The contribution from each ECG lead to the QRS detection signal is proportional to its measured quality based on the waveform amplitude, and the amount of muscle and baseline noise.

(a) True

(b) False

This question was addressed to me in an internship interview.

I need to ask this question from Bedside Patient Monitoring System topic in section Patient Monitoring System of Biomedical Instrumentation

Answer 1

Correct option is (a) True

For explanation I would say: The contribution from each ECG lead to the QRS detection signal is proportional to its measured quality based on the waveform amplitude, and the amount of muscle and baseline noise. The weighting factors are updated every 200 ms to allow for a quick adaption to signal quality changes.
