Question 1

What 3 things give narrow regular tachycardias?

Answer 1

sinus tach, supraventricular tach, atrial flutter

Question 2

Where are the p waves in SVT?

Answer 2

hidden in QRS (or sometimes after the QRS)

Question 3

What does atrial flutter look like?

Answer 3

“sawtooth”–sometimes only in 1-2 leads SO LOOK AT ALL LEADS!

Question 4

What do the P and T waves often look like in sinus tachycardia?

Answer 4

“camel humps”

Answer 5

thyroid disorder, PE, sympathomimetics

Answer 6

CHF, COPD, ischemic heart disease, alcohol use or withdrawal, thyroid disorders

Question 7

What are the 3 narrow irregular tachycardias?

Answer 7

atrial fibrillation, atrial flutter with variable conduction, multifocal atrial tachycardia

Question 8

What does a fib look like?

Answer 8

no distinct regular atrial activity–irregularly irregular

Question 9

What are the 3 wide regular tachycardias?

Answer 9

sinus tach w/ aberrant conduction, VT, and SVT with aberrent conduction (ex: BBB or WPW)

Question 10

What are the 2 wide irregular tachycardias?

Answer 10

a fib w/ bundle branch block and a fib with WPW
