Signs & Symptoms of Extremely High Blood Pressure
More than 50 million Americans have high blood pressure, according to Cedars-Sinai. Blood pressure is the pressure of the circulating blood on blood vessel walls. This measurement is an indication of overall health and is divided into systolic and diastolic pressure. Systolic pressure refers to the force in the arteries when the heart beats and pumps the blood out. Diastolic pressure refers to the force in arteries when the heart is at rest, in between beats. Normal blood pressure is 120 over 80, and anything above 140 over 90 is considered high. Extremely high blood pressure, or malignant hypertension, occurs in rare instances and can be serious and life-threatening. It is important to recognize the signs and symptoms.
