Wellens Syndrome
WPW
RVH
Increased QRS duration, secondary R wave in V1 and V2, deep S V5V6 tall P waves in II,III,aVF
Left Bundle Branch Block
Prolonged QRS duration, q wave absent V5 and V6, no secondary R wave in V1
Prolonged QRS, no q wave in V5 and V6, prominent changes in ST segment and T wave
Right Bundle Branch Block
Wide QRS, secondary R wave in V1 and delayed S waves in I, aVL, V5 and V6
Sinus tachycardia, prolonged QRS duration, secondary R wave in V1 and V2, prominent S waves in V5 and V6>
IHD
Recent Anterolateral MI
Acute Inferior MI, Old Anteroseptal MI
ST elevation II,III,aVF, ST depression and T wave inversion I,aVL, V2-V5. Poor R wave progression
Acute Anterior STEMI, old inferior MI
ST elevation, no R waves V1-V6, Pathological Q waves in III and aVF
???Q waves V1-V5, lack of R wave in precordial leads, ST elevation V2-V5, T waves inverted I, aVL, V2-V5
Recent Anterior-lateral STEMI
ST elevation I, aVL, V2-V6, ST depression a VR, III, aVF. Loss of R waves, path Q waves I,aVL, V2-V4
Old Inferior STEMIM
Pathological Q waves in II, III, aVF with inverted T waves. Flattened T waves in V5=V6
Old Anterolateral MI
Pathological Q waves in I,aVl, V2-6, Loss of R waves V2-5, T waves inverted V5-6 and flattened or inverted in II,III, avF, ST elevation V2-4
Acute Inferior STEMI
Acute Inferolateral MI
ST elevation I, II, aVF, aVL, V3-V6, Pathological Q wave in aVL
Acute Inf MI and True Posterior
NSTEMI
Sinus bradycardia, ST depression widespread, T wave inversion V2-5
Hypertension
Voltage criteria for LVH are met, Ventricular activation time is prolonged
Voltage criteria for LVH are met, pathological Q waves in III and aVf and ST elevation suggest LVH and recent Inferior MI. Ventricular activation time is prolonged
