Figure 1: Progressive changes in ECG with increasing severity of hyperkalaemia.
Figure 2: ECG in a patient with severe hyperkalaemia (serum K⁺ 9.1 mmol/L) illustrating peaked T waves (a), diminished P waves (b), and wide QRS complexes (c).
Figure 3: Arrhythmias in patients with severe hyperkalaemia illustrating bradycardia with wide QRS [K⁺ 9.6 mmol/L] (a), sine wave with pause [K⁺ 9.3 mmol/L] (b), sine wave without pause [K⁺ 8.4 mmol/L] (c), and ventricular tachycardia [K⁺ 9.1 mmol/L] (d).
Figure 4: There are five key steps in the treatment of hyperkalaemia (never walk away without completing all of these steps).
Figure 5: ECG on admission (a) and following 20ml 10% calcium gluconate IV (b) in a patient with serum K⁺ 9.3 mmol/L who presented with generalised weakness.
