Terms | Definitions |
|---|---|
 polarization | is the resting state of the myocardial wall when there is not electrical activity in the heart and is recorded on the ECG strip as a flatline |
| depolarization occurs | when the electrical system if the heart stimulates a myocardial cell, ____________, resulting in the contraction of the stimulated heart muscle |
| after depolarization | the heart muscles cells must return to a resting state before they can be electrically simulated again |
| repolarization | is the process of reaching the resting state before they can electrically simulated again |
| waves or deflection | electrocardiograph records a series of_______________ above or below a baseline on the EGK |
| of the cardiac cycle | each deflection/wave corresponds to a particular part |
| P-wave, the Q-wave, the R-wave, the S-wave, and the T-wave | the normal EKG cycle consists of waveforms that are labeled as the |
| PQRST | entire cardiac cycle can be called the complex |
