Question

AZTEC contains digital logic, which is able to detect?

(a) Baseline wander

(b) QRS complex

(c) R-R interval

(d) Motion artifact

I had been asked this question during an interview for a job.

This interesting question is from Central Monitors topic in division Patient Monitoring System of Biomedical Instrumentation

Answer 1

Right answer is (a) Baseline wander

The best I can explain: AZTEC contains digital logic, which is able to detect base line wander. Also, the sum of absolute values of all slopes is used for noise detection, but sudden bursts of muscle artifact or an excursion from baseline are distinguishable from an ECG wave only if the condition persists.
