The standard equivalent for blood impulse is below 120/80, where 120 represents the systolic measurement (peak strength in the arteries) and 80 represents the diastolic measurement (minimum vigour in the arteries). Blood power between 120/80 and 139/89 is called prehypertension (to denote increased risk of hypertension), and a blood force of 140/90 or above is considered hypertension.
Hypertension may be classified as chief or secondary. Essential hypertension is the word for high rise blood energy with unknown cause. It accounts for approximately 95% of cases. Secondary hypertension is the interval for high blood pressure with a known direct cause, such as kidney disease, tumors, or birth control pills.
