Week 7 Scholarly Questions and Analytical Thinking

What is the rate of a wandering atrial pacemaker?
Any beat outside the SA node is referred to as an ____ beat. (answer: ectopic)
Practice Practice Practice the sinus and atrial rhythm strips in your text.

What is the rate of atrial tachycardia?
Are the p waves of atrial tachycardia similar or hidden?
True or False: The p waves are hidden in the T wave with atrial tachycardia? (Answer" True)
Is the rhythm usually regular or irregular with atrial tachycardia?
What does paroxysmal mean?
Describe atrial flutter.
What do the flutter waves look like?
Always inspect the flutter waves—do they have a ‘saw tooth’ or ‘undulating‘ look on the rhythm strip?
We report atrial flutter in a F wave to QRS ratio. Therefore, what does an atrial flutter with a 4:1 AV conduction mean? What does atrial flutter with a 2:1 conduction mean? What does atrial flutter with variable conduction mean?
Can you measure the PRI with atrial flutter or is it indeterminate?
Is the QRS normal in atrial flutter? (Answer Yes, because the flutter electrical message is occuring in theatria)
What type of rhythm may you see with atrial flutter? (note, it can be regular or irregular depending on whether the AV conduction is consistent or variable)
Describe atrial fibrillation.
Can you see any p waves in atrial fibrillation. What do we call them? (answer: fib or fibrillation)
Is the rhythm regular or irregular in atrial fibrillation?
What is the rate for atrial fibrillation controlled?
What is the rate atrial fibrillation uncontrolled?
What is greater health risk: uncontrolled or controlled atrial fibrillation? (Yes, uncontrolled)

Let's Review:
What are the classification ranges for the axis of the mean QRS? Make sure you know the range and how to classify! What is normal axis? What is left axis deviation? What is right axis deviation? What is extreme right axis deviation? How do you correctly report the mean QRS (also called the QRS axis)?

Remember, EKG involves learning the comprehensive language of electrocardiography and thus all tests will have a comprehensive nature.
