Note: Please choose one answer (Yes or No) and if it is No, please correct the sentence. 1- The Na+/K+ pump maintains the resting potential inside the cell by taking K+ out of the cell and bringing Na+ into the cell. 2- A big challenge in ECG recording is the white noise with equal intensity in time domain is usually contaminate ECG. 3- Cardiac cells in human are a semipermeable membrane which allows to Na", K", and few proteins to flow in and out of the cells.

1- The Na+/K+ pump maintains the resting potential inside the cell by taking K+ out of the
cell and bringing Na+ into the cell.
2- A big challenge in ECG recording is the white noise with equal intensity in time domain is
usually contaminate ECG.
3- Cardiac cells in human are a semipermeable membrane which allows to Na*, K*, and few
proteins to flow in and out of the cells.
4- In the hospital, to measure the potential at position V2, it must subtract lead V2 from
Wilson lead which is connected three leads (RA, LA, and V1).
5- Lead Il is a unipolar lead because it is created by subtracting two electrodes (RA and LL).
6- Atrioventricular node (AVN) has some particular cells called natural pacemaker cells that
help to pass ionic currents from atrium to ventricular.
7- The action potential in the heart muscle is due to the changes of the membrane
potential during the depolarization and hyperpolarization of the cell.
8- A signal can be represented as an independent variable (e.g., voltage) as a function of an
independent variable (e.g., time).
