Doctors Medicines MCQs Q&A

In order to detect the QRS, the detection threshold is kept as ________ to prevent the detection of T waves or baseline noise as QRS complexes during a complete heart block or asystole.

In order to detect the QRS, the detection threshold is kept as ________ to prevent the detection of T waves or baseline noise as QRS complexes during a complete heart block or asystole. Correct Answer 0.00015 V

In order to detect the QRS, the detection threshold is kept as 0.15 mV to prevent the detection of T waves or baseline noise as QRS complexes during a complete heart block or asystole. For optimal performance and to prevent false alarms, the lead selected for monitoring should have adequate amplitude.

Vibration signature has well-defined peaks whereas the noise signal is smeared. 3. The intensities of noise signatures arc much less than that of vibration signatures. 4. Detection of vibration signature calls for a microphone whereas that of noise can do with a pickup. Select the correct answer using the code given below.
