HyperKalaemia Peaked T wave ( empire state building!) P wave flattening Prolonged PR QRS widens Increase in size of U wave
T wave flattening ST depression Prolonged QT interval U wave Nb – Hypomagnesia can be identical!
Hypercalcemia Malignant tumours Excessive vitamin d May be life threatening!!!!!! ECG- Shortens QT interval
Digitalis toxicity ST depression Characteristic sag
Hypothermia Core body temperature of < 95 degrees Prolongation of QRS Bradycardia Development of J wave Distinctive narrow positive wave the Osborn wave/J wave/J deflection/camel’s humpDistinctive narrow positive wave the Osborn wave/J wave/J deflection/camel’s hump Occurs at the junction of the QRS complex and ST segmentOccurs at the junction of the QRS complex and ST segment
