RVH is high blood pressure caused by RAS. Blood pressure is written with two numbers separated by a slash, 120/80, and is said as 120 over 80. The top number is called the systolic pressure and represents the pressure as the heart beats and pushes blood through the blood vessels. The bottom number is called the diastolic pressure and represents the pressure as blood vessels relax between heartbeats. A persons blood pressure is considered normal if it stays at or below 120/80. High blood pressure is a systolic pressure of 140 or above or a diastolic pressure of 90 or above.1
