Excitability correct answers the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization correct answers occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity correct answers the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex:...

According to the principles of differential amplification, electrical interference can best be prevented if - Answer- The impedances of input elecrodes are similar During a recording, the technologist notices that the HFF on an EOG channel is set at 15Hz. Which of the following is correct? - Answer- Rapid eye movement signals will be attenuated G1 receives an input voltage of -100uv while G2 simultaneously receives -50uv. The polysomnograph sensitivity is set at 10uv/mm. What will be the p...
