Vessel: Left main stem
Posterior ECG leads and artery
Leads: V1, V2, V3 (recip)
Vessel: RCA
Long QT causes
Low K, low Ca
Macrolides, Tricyclics, anti-arhythmic
SAH
Short QT causes
Beta blocker, digoxin, phenytoin
Abnormal T wave if in leads:
I, II, V4-6
J waves in ECG causes
hypothermia, SAH, hypercalcaemia
AVRT p wave location
Visible between QRS complexes
AVNRT p wave location
Absent or immediately before/after QRS
Digoxin ECG
T wave inversion, down sloping ST depression
PE ECG
S1QIIITIII, right ventricle starin (RAD, dominat R wave)
Hyperkalaemia ECG
Tall tented T waves
Widened QRS
Absent P waves, sine wave appearance
Hypokalaemia ECG
Small T waves, ST depression
Prolonged QT, u waves
