ECG ONLY!! Flashcards
Hypertrophic cardiomyopathy
- Left ventricular hypertrophy
- Non-specific ST segment
3.T-wave abnormalities - Progressive T wave inversion
- Deep Q waves
- AF occasionally seen
Brugada syndrome
- Convex ST elevation >2mm in >1 V1-V3
- T wave inversion
- Parital RBBB
What medications are use to diagnose Brugada that makes ECG chnages more apparent?
1.Flecainide
2. Ajmaline
Wolff-parkinson-white
-Short PR interval
-Wide QRS
-Delta wave (slurred upstroke in QRS)
Posterior MI
1.Changes V1-V3
2.Reciprocal chnages of STEMI
-Horizontal ST depression
-Tall,broad R waves
-Upright T waves
-Dominant R wave in V2
3. ST elevation and Q waves in posterior leads V7-V9
What does this show
V5 can see frequent premature ventricular complexes
RBBB
v1 -M
v6- W
LBBB
V1 - W
V6 - M
Main ECG finding of hypercalcaemia?
Shortened QT interval
Pericarditis
- Saddle shaped ST elevation
- PR depression
NOTE: changes are widespread
Most specific ECG marker for pericardidits?
PR depression
Digoxin toxicity
- Down-sloping ST depression
- Flattened/inverted T waves
- Short QT interval
ECG hypokalaemia?
- U waves (always follow T waves)
- Small or absent T waves
- T waves sometimes inverted
- Prolonged PR interval
- ST depression
- Long QT
Inferior MI lead changes ?
II, III, AVF
-Right coronary artery
Hypothermia ECG chnages?
When temp 32-33
1. J waves or osborn waves
2. Acute ST elevation
ECG changes hypercalcaemia?
Shortened QT
Anteroseptal ECG and artery?
1.V1-V4
-Left anterior descending
STEMI elevlation
2mm in V1-V6
1mm in II, III, avF, avL
Lateral ECG changes and artery?
I, aVL -/+ V5-V6
Left circumflex
inferior MI ECG and artery
I, III, aVF
right coronary artery
Left ventricular aneurysm ECG findings?
-Damage of myocardium causing aneurysm formation
-Persistent ST elevation
