1

• Ventricles are firing but pt unable to tolerate this type of conduction for long and will eventually go into asystole – no conduction.

Asystole

2

• Always irregular
• Seen in elderly a lot
• Atria is quivering and perfusion is bad
• Typcially put on Digitalis to help SA node firing, along with Coumadin, Lovenox, or Xarelto to help prevent a clot

Atrial fibrillation

3

Occurs before pt goes into systole
Ventricles are firing

Ventricular fibrillation

4

Perfusion is not good, leads to ventricular fibrillation

Ventricular tachycardia

5

• Atria are doing their own thing and the ventricles are doing their own thing = no communication. This cannot be sustained for very long and will require immediate external pace maker until pt can have a pacemaker inserted. Critical situation.

3rd degree heart block

6

Normal parameters for PR interval

0.12 to 0.20 seconds

7

Normal parameters for QRS interval

0.08 to 0.12 seconds

8

Elevated/depressed T wave suggests?

Ischemia
