Careful palpation of the upper and lower limb pulses would make one suspect coarctation as the cause of hypertension. The lower limb pulses are weak and delayed. Confirmation can be made with cardiac ultrasound and angiograms.
Pregnancy
An increase of blood pressure of 30/15 mmHg or more from a normal of 140/80, in pregnancy is called gestational hypertension. This usually happens in primigravida in the 20 week. When hypertension is associated with proteinuria and oedema it is termed pre-eclampsia. This can progress to eclampsia with cerebral involvement and seizures.
