Correct answer: COrthostatic hypotension with bradycardia

The combination of falls soon after standing, a significant postural blood pressure drop and beta-blocker-associated bradycardia best explains the presentation. BPPV causes positional spinning vertigo rather than presyncope with documented postural hypotension. Medication-related cardiovascular causes are common and reversible contributors to falls in older people.
