Ventricular tachycardia is an abnormal heart rhythm where the ventricles beat quickly, but evenly. This is similar to ventricular fibrillation, but the ventricles beat quickly and unevenly. The term tachycardia refers to a fast heart rate.
White coat syndrome (WCS) is a temporary elevation of blood pressure caused by excitement or anxiety that does not necessarily constitute hypertensive disease, but may indicate an inclination towards its development. White coat syndrome occurs in a patient whose blood pressure is consistently higher at a physician’s office than when measured at home. Patients may or may not have an existing diagnosis of hypertension.
