A

between 140/90mmHg and 180/120mmHg

22
Q

How does ambulatory blood pressure measure BP?

A

This 24-hour blood pressure measurement takes at least 2 measurements per hour

Q

What is ambulatory BP done to combat?

A

To combat white coat syndrome and account for people who get nervous in a clinic setting

26
Q

What investigations can be done to assess end organ damage in severe hypertension?

A
  • Fundoscopy (for retinopathy)
  • ECG (for Left Ventricular Hypertrophy)
  • Urinalysis (Renal dysfunction)
