Term
| electrocardiogram (ECG) is composed of a P-wave, a QRS complex, and a T-wave. these 3 components are measured: |
|
Definition
| once during each cardiac cycles |
|
|
Term
| the electrocardiogram (ECG) measures: |
|
Definition
| action potential in the atria and the ventricles |
|
|
Term
| in the ventricles of the human heart, the depolarizing phase of the action potential is associated w/: |
|
Definition
|
|
Term
| in most people, the heart is located: |
|
Definition
|
|
Term
| heart lies in the thorax w/ its long axis: |
|
Definition
| pointing downward, at some angle b/w horizontal and vertical |
|
|
Term
| in the Lead I orientation, signals are recorded from the recording electrodes from: |
|
Definition
|
|
Term
| in the Lead II orientation, signals are recorded from the recording electrodes from: |
|
Definition
|
|
Term
| the amplitude of the QRS wave in lead I is smaller than the amplitude of the QRS wave in lead II. this is b/c: |
|
Definition
other options are both correct
(distance b/w 2 wrist in lead I is shorter
distance b/w the L.wrist & L.ankle is larger) |
|
|
Term
| if the heart were in the midline of th chest, then the distance b/w the heart and each recording electrode in lead I orientation would be: |
|
Definition
|
|
Term
| if the tip of the heart pointed at the midline of the chest, then the 2 intersecting lines would cross at: |
|
Definition
|
|
Term
| in the lab simulation, it is assumed that the amplitude of the ECG is an indication of: |
|
Definition
| how far the heart lies off midline |
