| | | | | | | |
when blood stops flowing properly to part of the heart and the heart
| | | | | | | | | | | | |
muscle is injured due to not receiving enough oxygen.
| | | | | | | |

| | | | | | | | |
occur when myocardial ischemia is not resolved and there is a
| | | | | | | | | | |
continued lack of oxygen | | |

What is electrophysiology in relation to the heart? - CORRECT
| | | | | | | | | |
ANSWER✔✔-How the heart initiates, how it responds, and how it
| | | | | | | | | |
transmits electrical impulses | |
T/F the heart has to depolarize in order to repolarize - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-True
What is depolarization? - CORRECT ANSWER✔✔-electrical activation of
| | | | | | | |
a cell caused by the influx of sodium into the cell while potassium exits
| | | | | | | | | | | | | |
the cell
|
What is repolarization? - CORRECT ANSWER✔✔-Return of the cell to
| | | | | | | | | |
resting state, caused by reentry of potassium into the cell while sodium
| | | | | | | | | | | |
exits the cell.
| |
, What is the refractory period? - CORRECT ANSWER✔✔-a period of
| | | | | | | | | |
inactivity after a neuron has fired
| | | | |

| | | | | | | | |
which cells are incapable of depolarizing
| | | | |
What is the relative refractory period? - CORRECT ANSWER✔✔-phase in
| | | | | | | | |
which cells require stronger-than-normal stimulus to depolarize
| | | | | | |

| | | | | | | | | |
ANSWER✔✔-Produces left ventricular hypertrophy | | |
What is hypertrophy? - CORRECT ANSWER✔✔-increase in size of cells
| | | | | | | | |
How does calcium affect the heart muscle? - CORRECT ANSWER✔✔-
| | | | | | | | |
contributes to the electrical signal that coordinates the heart function
| | | | | | | | |
How does potassium affect the heart muscle? - CORRECT ANSWER✔✔-
| | | | | | | | |
Helps your heart beat at the right pace by helping control the electrical
| | | | | | | | | | | | |
signals of the myocardium
| | |
What is the cardiac cycle? - CORRECT ANSWER✔✔-one complete
| | | | | | | | |
heartbeat
