I, AVL, AVF, V5-V6

19
Q

What does the presence of a U wave indicate?

A

Hypokalemia

20
Q

Indication of a first degree AV Block?

A

Prolonged PR Interval (longer than 0.2 seconds)

21
Q

What is an indication of a second degree AV block?

A

PR Interval greater than 0.2 seconds

Increased ratio of P wave: QRS intervals (2 or more atrial impulses before QRS-T sequence)

22
Q

What is the presentation of a Wenckebach AV Block?

A

The PR interval gets progressively longer, until you see no more QRS intervals

23
Q

What is the presentation of a Mobitz II AV block?

A

Dropped QRS complex with no lengthened PR interval.
