1

Right bundle branch block looks like?

'M' in V1 'RSR' pattern

2

Left bundle branch block looks like?

'W' in V1
'M' in V6

3

what is the average direction of depolarization of ventricles?

left to right

4

what is left axis deviation usually due to?

left anterior fascicular block
left anterior hemiblock

5

what is bifascicular block?

RBBB and left axis deviation from a left anterior fascicular block

6

does a RBBB affect cardiac axis?

Nope, still normal cardiac axis

7

septum is depolarized from which direction?

left to right

8

what pattern in RBBB?

'RSR' in V1

9

what pattern in LBBB?

'M' in V6

10

Width of QRS complex?

120ms
less than 3 squares

11

how do ventricular rhythms spread?

slower, and through purkinje
Wide QRSs and inverted 't' waves

12

what are escape rhythms?

ventricular origins of depolarization

13

what is nodal escape?

when region around AV node takes over pacing

14

what is an ectopic beat?

depolarization originating in abnormal location

15

atrial extrasystoles have?

abnormal P wave

16

junctional extrasystole has?

no P wave at all

17

ventricular extrasystoles look? important?

wide, any shape,
common and usually not important

18

what is R on T phenomenon?

when ventricular systoles occur at peak of T-waves

19

T waves look how in supraventricular beats vs. ventricular beats?

supra: same way up
ventricular beats: inverted T waves

20

P wave affected in ventricular extrasystole?

Nope, SA node not affected

21

P wave affected in supraventricular extrasystole?

Yes it resets the cycle

22

P wave affected in supraventricular extrasystole?

Yes it resets the cycle

23

atrial tachycardia faster than how many beats/min?

>150beats/min

24

atrial flutter rate is greater than?

250/min

25

where to look to see atrial flutter?

Lead II
aVR
aVF

26

QRS is?

onset of conduction through the ventricles

27

QT?

The time the ventricle is contracting
