CPR 22 - Application of ECG Basics Flashcards
What does the absence of a Q wave indicate?
There is an SA to AV coduction problem; heart block.
What does the presence of a Q wave without a P wave indicate?
That the Q wave is not derived from the SA node. The ventricles may be contracting prematurely.
What are the normal arrhythmias?
What are the primary causes of cardiac arrhythmias?
Altered conduction anywhere along the conduction pathways
Altered automaticity (issues with pacemaker cells)
What is a partial cardiac conduction block? When does an ECG indicate a partial conduction block?
What is a 1st degree AV block? What causes it and how is it treated?
What are the types of 2nd degree blocks?
Mobitz Type 1
Mobitz Type 2
Bundle Branch Blocks
What is a Mobitz Type 1 block? How does it appear on an ECG? In what populations is it most commonly seen? How is it treated?
What is a Mobitz Type 2 block? How does it appear on an ECG. How is it treated?
What is a bundle branch block? How does it appear on an ECG?
What is a 3rd degree cardiac block? How does it appear on an ECG? How is it treated?
What is cardiac fibrillation?
A condition where the frequency of generation of APs is so high that there is no coordinated contraction of the myocardium.
What are the complications associated with atrial fibrillation? In what populations is it mostly seen?
How will atrial fibrillation appear on an ECG?
How will ventricular fibrillation appear on an ECG? How is it treated?
No
No
Yes
No
