Myocardial Ischemia
Inferior STEMI
Hyperkaelemia
Peaked T waves (usually the earliest sign of hyperkalaemia) P wave widens and flattens PR segment lengthens P waves eventually disappear Prolonged QRS interval with bizarre QRS morphology High-grade AV block with slow junctional and ventricular escape rhythms Any kind of conduction block (bundle branch blocks, fascicular blocks) Sinus bradycardia or slow AF Development of a sine wave appearance (a pre-terminal rhythm)
Pericarditis
Widespread concave ST elevation and PR depression throughout most of the limb leads Reciprocal ST depression and PR elevation in lead aVR (± V1). Sinus tachycardia is also common in acute pericarditis due to pain and/or pericardial effusion.
Pericarditis
Widespread concave ST elevation PR depression throughout most of the limb leads (I, II, III, aVL, aVF) and precordial leads (V2-6). Reciprocal ST depression and PR elevation in lead aVR (± V1). Sinus tachycardia is also common in acute pericarditis due to pain and/or pericardial effusion.
Right Bundle Branch Block
Broad QRS > 120 ms RSR’ pattern in V1-3 (‘M-shaped’ QRS complex) Wide, slurred S wave in the lateral leads (I, aVL, V5-6)
