HypokalaemiaPage 42
Broad complex tachycardia – diagnosis?Page 43
Broad complex tachycardia – diagnosis?Torsades de Pointes – QT prolongationPage 44
Hypokalaemia Decreased extracellular K – hyperexcitability: re-entrantarrhythmias Increase amplitude and width of P wave Prolonged PR interval T flattening / inversion ST depression Prominent U waves Apparent long QT (QTU fusion) SVEs, VPBs SVT (AF, atrial flutter, atrial tachy) VT, VF and Torsades de PointesPage 45
HyperkalaemiaPage 46
Hyperkalaemia Increased extracellular K – reduces myocardial excitability Repolarisation changes:Peaked T waves Atrial paralysis:P wave widens and flattensPR prolongationP wave disappears Conduction abnormality and bradycardia:QRS prolongs / bizarreHigh grade AV block, junctional and ventricular escape rhythmsSinus brady or slow AFSine wave (pre terminal) Cardiac arrest:AsystoleVFPEA with bizarre wide QRSPage 47
