Exam 1 - EKG

Question 1

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

Answer 1

Asystole

Question 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

Answer 2

Atrial fibrillation

Question 3

Occurs before pt goes into systole

Ventricles are firing

Answer 3

Ventricular fibrillation

Question 4

Perfusion is not good, leads to ventricular fibrillation

Answer 4

Ventricular tachycardia

Question 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.

Answer 5

3rd degree heart block

Question 6

Normal parameters for PR interval

Answer 6

0.12 to 0.20 seconds

Question 7

Normal parameters for QRS interval

Answer 7

0.08 to 0.12 seconds

Question 8

Elevated/depressed T wave suggests?

Answer 8

Ischemia
