Correct answer: EECG, electrolytes, renal function and a timed digoxin level

Symptoms, bradycardia and reduced renal clearance suggest digoxin toxicity. Urgent ECG and electrolyte/renal assessment are needed. A digoxin concentration can support interpretation when sampled at least 6 hours after the last dose, but treatment of serious toxicity is guided by clinical and ECG findings.
