1.	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.(a) 0.15 V(b) 0.015 mV(c) 0.015 mV(d) 0.00015 VI have been asked this question in final exam.Question is from Bedside Patient Monitoring System topic in section Patient Monitoring System of Biomedical Instrumentation
Answer» The CORRECT answer is (d) 0.00015 V For explanation I would say: 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.
