A 81-year-old male patient is brought in by ambulance with persistent diarrhoea and subacute symptoms of lethargy, weakness of the leg muscles and malaise. He is taking perindopril 4 mg twice a day.

His electrocardiogram on admission is enclosed in Fig. 1. What would you expect to find in your laboratory results?
