Name all affected leads in interior STEMI + its blood supply
Right Coronary Artery: II, III, aVF
ST depression in I, aVL
Name all affected leads in anterior STEMI + its blood supply
Which leads are considered septal?
Left Anterior Descending: V1-V4
V1-2 considered ‘septal’
If LAD occluded, will present with anterolateral STEMI
Name all affected leads in lateral STEMI + its blood supply
Explain why isolated lateral STEMI is rare
Left Circumflex: V5-6, I, aVL
ST depression in III, aVF
LCx occlusion would result in Inferior-posterior-lateral STEMI
LAD occlusion would result in anterolateral STEMI
Isolated lateral infarction due to occlusion of smaller branch arteries such as the D1, OM or ramus intermedius
Name 5 ECG signs of PE
- Sinus tachycardia
- RBBB (?R straining)
- Right Axis Deviation (?R straining)
- R straining (T wave inversion and ST depression in inferior and anterior leads)
- S1 Q3 T3: deep S wave in lead I, Q wave in III, inverted T wave in III
- AF

3 cardiac causes of syncope
- Arrhythmia
- Tachy/brady, Long QT associated w VT - Outflow obstruction
- AS, PE - Postural hypotension
- > 20 SBP difference
