How does amplification affect the ECG signal quality?.
- A.It decreases the signal-to-noise ratio
- B.It allows for better visualization of the heart's electrical activity
- C.It reduces the overall signal strength
- D.It complicates the signal processing
Model answer
What a good answer should say
- It allows for better visualization of the heart's electrical activity
Explanation
Why this works
Amplification increases the strength of the ECG signals, which allows for better visualization of the heart's electrical activity. This mechanism enhances the clarity of the waveform, making it easier for healthcare professionals to diagnose and monitor cardiac conditions, thus improving patient care.
