When the sinoatrial (SA) node fires, atrial depolarization occurs.

In an ECG complex, this results in:

When the atrioventricular (AV) node fires, ventricular depolarization occurs.

In an ECG complex, this results in:

In an ECG complex, ventricular repolarization is represented by a:

True or False

Transcutaneous pacing is NOT used only in emergency situations and does NOT use defib pads to deliver an electrical stimulus?

True or False
