Flashcards in Basic EKG interpretation II Deck (15):
1

II, III and aVF

for atrial flutter
goes at 300

2

A-V goes at what for atrial fib.

150

3

atrial flutter looks like

a saw in lead II, III and aVF

4

atrial fibrillation looks like

-no p-waves
-irrregularity of QRS's

5

bundle branch block

conduction through purkinje

6

right bundle branch block

V1 and V6 will show
-wider QRS (greater than 120 ms)
-split the QRS into two halves, early part and terminal
rSR' in V1, inverted T wave on side of the bundle branch block is normal (secondary T wave change)
qRs V6

7

if block left bundle

V1 rS
V6 R

8

first degree AV block

fixed PR prolongation (greater than 5 small boxes, 1 big box)
-all p waves go to ventricle

9

second degree AV block type I

Mobitz Type I, Wenckebrach (GWI)
-gradual PR prolongation
-see pauses, grouped QRS

10

most common cause for a pause on rhythm strip

non-conducted atrial beat that comes early

11

Second degree type II

Mobitz type II, non-wenckebach (NWII)
-unpredictable AV block
-p waves conduct and then all of sudden they don't
-conduction can be normal and then not normal
-conduction in ventricle is abnormal too
-bad conduction system
-QRS dropped
-sometime seen with first degree block or bundle branch blocks

12

third degree

AV dissociation
-p waves and QRS don't talk to each other, doing different things

13

where to look for bundle branch blocks

V1, V6 and lead I

14

do you need a pacemaker for Wenckebach block?

No

15

late depolarization coming towards you and in a right lead (like V1)
