Osborne Waves

Hypothermia

2

5 Steps for ECG

Rate, Rhythm, Axis, Hypertrophy, Infarction

3

What to look for Rhythm

p before every QRS, QRS after every P, P and QRS intervals

4

Irregular rhythms

Sinus arrhythmia, Wandering pacemaker, multifocal atrial tachycardia, atrial fibrillation,

5

Escape Rhythms

atrial escape rhythm, Junctional escape rhythm, ventricular escape rhythm

6

Tachyarrhythmias

Atrial flutter(sawtooth pattern), atrial fibrillation, ventricular flutter, Ventricular fibrillation

7

1st degree AV block

prolonged PR interval >0.2 seconds

8

2nd degree AV block

Mobitz/Wenkebach . PR lengthens with a dropped QRS

9

2nd degree AV block Mobitz II

some P waves do not produce a QRS

10

3rd degree AV block

complete heart block. no P waves produce a QRS

11

Right BBB

R, R' in V1 or V2

12

Left BBB

R, R' in V5 or V6

13

What to look for in Axis

QRS + or - in leads 1 and aVF, is axis norma?

14

Normal Axis deviation

QRS upright in Lead 1 and in aVF

15

inferior MI

leads II, III, aVF, right coronary artery

16

anterior, anteroseptal MI

leads V1-V4, left anterior descending artery

17

lateral MI

v5-v6, 1, aVL, left circumflex artery

18

posterior MI

ST depression in V1, V2, left circumflex or right coronary artery

19

Anterior leads

V3, V4

20

Septal leads

V1, V2

21

inferior leads

II, III, aVF

22

Lateral leads

I, aVL, V5, V6

23

life threatening DDX

ACS, aortic dissection, PE, pneumonthorax, pericardial tamponade, Mediastinitis

24

Non-life threatening DDX

pleurisy, CHF, pneumonia, angina pectoris, pericarditis, endocarditis, PUD, GERD, panic disorder

25

Sick sinus syndrome ECG

alternating tachy/brady

26

SSS TX

pacemaker

27

SVT TX

Unstable- cardiovert. Stable- vagal manuever or carotid massage.
Drugs- adenosine 6mg IV, diltiazem or CCB, BB

28

Torsades TX

Magnesium sulfate

29

Ventricular fibrillation TX

defibrillation 360J monophasic, 120-200J Biphasic

30

Asystole/PEA algorithm

CPR 2 min, IV access/epi, continue CPR until shockable rhythm
