Ecg part 3

3. • You will recall (no
doubt) that the
presence of a large
R wave exceeding
the amplitude of
the accompanying
S wave in lead V1
is also one
criterion for the
diagnosis of right
ventricular
hypertrophy.
• The diagnosis of
right ventricular
hypertrophy,
however, also
requires the
presence of right
axis deviation,
which is not
present in
posterior
infarction.

8. • DIAGNOSIS OF MI CANT BE MADE IN CASES OF LBBB or WPW by ECG

9. T Abnormalities
Infarct = localized T changes
Electrolyte imbalance= Diffuse changes

10. Hyperkalemia

11. Hypokalemia

12. Osborne wave (J wave)

14. Arrhythmias
• Sinus Tachycardia
• Sinus Bradycardia
• Sinus Arrhythmia
• Sinus Arrest, Asystole
and Escape rhythms
• Junctional escape
rhythm
• Idioventricular rhythm
• Accelerated
idioventricular rhythm
• Premature Beats
• VEBs ( PVC )
• APC
• Narrow complex
Tachycardias
• A fib
• MAT
• Wandering pace maker
• A flutter
• SVT
• Broad Complex
Tachycardias
• VT
• V fib
• Heart Blocks
• Fisrt degree
• Second degree
• Third degree
• Bundle Branch blocks
• LBBB
• RBBB
• Bifascicular Block
• Trifascicular Block
• Pre-Excitation
Syndromes
• WPW
• LGL

15. • RBBB + Any AXIS DEVIATION is called BIFASCICULAR block
• RBBB + AXIS DEVIATION + Prolonged PR interval is called Tri Fascicular
Block

16. Sinus Arrest; Escape rhythms; Asystole

18. Escape Beats and Escape Rhythms

19. • P Waves are not
identical to previous P
waves

23. Premature Beats

24. Premature Beats
