No. Systolic is the pressure exerted on the walls of the arteries when the heart is contracting. Diastolic is the pressure exerted on the walls of the arteries when the heart is at rest. Hence, since...
Blood pressure readings are always expressed as two values, one high and one low, representing the squeeze (systolic) and relax (diastolic) phases of the heart's pumping. The units of blood pressure...
The systolic pressure is always stated first and the diastolic pressure second. For example: 122/76 (122 over 76); systolic = 122, diastolic = 76. Blood pressure of less than 140 over 90 is...
