Q

A 32-year-old man presents with a 2-week history of frequent urination and excessive thirst. He has also noticed that he feels much weaker than usual, and is struggling to complete his usual gym routine. He has been to see his GP once before because his blood pressure was high on multiple occasions, however, he did not return to receive treatment. His blood pressure is measured again and it is 184/94 mm Hg. What would you expect to see on the ECG of this patient?

A.Tented T waves 
B.Absent P waves 
C. ST elevation 
D.J waves 
E.U waves
A

E.U waves
This patient has Conn’s syndrome – a condition in which an aldosterone-secreting adenoma leads to inappropriately elevated aldosterone levels. The excessive sodium reabsorption and potassium excretion caused by the high aldosterone leads to hypertension and hypokalaemia. Hypokalaemia induces nephrogenic diabetes insipidus, which, consequently, leads to polyuria and polydipsia. Furthermore, muscle weakness is another feature of hypokalaemia. The main ECG features of hypokalaemia are U waves, ST depression, flattened T waves and prolonged PR interval. In any young patient presenting with hypertension, consider secondary causes such as Conn’s syndrome, coarctation of the aorta and renal artery stenosis.
Tented T waves are a feature of hyperkalaemia. Absent P waves can be seen in several different conditions, most notably atrial fibrillation and supraventricular tachycardia. J waves (sometimes referred to as Osborn waves) are see in hypothermia.
