Postural orthostatic tachycardia syndrome (POTS) is a heterogeneous autonomic disorder characterised by orthostatic intolerance and a rise in heart rate by at least 30 bpm or an absolute heart rate value of at least 120 bpm within 10 min of standing or during a tilt table test. Overwhelmingly, POTS affects young Caucasian women, which can lead physicians to miss the diagnosis in men or non-white patients. We describe a case of 29-year-old African-American man who developed lightheadedness, generalised weakness, tachycardia and palpitations and was subsequently diagnosed with POTS. We review its clinical features, differential diagnosis, pathophysiology and treatment options. We also emphasise that POTS should be considered as a differential diagnosis in any patient presenting with typical clinical features, who may not be in the usual demographics of the disorder.
