Appropriate and standard measurement of blood pressure (BP) is imperative to accurately diagnose, manage, and treat hypertension. Caffeine, exercise, and smoking should be avoided for at least 30 minutes prior to measurement and patients should be seated with the arm being measured at heart level. Indications for ambulatory BP monitoring include suspected “white coat” hypertension, hypotensive symptoms on therapy, episodic hypertension, and autonomic dysfunction.
