What is the difference between Pacemaker and Defibrillator? â¢ Pacemakers are medical devices used to manage non-emergency cardiac dysrhythmias. â¢ Defibrillators are used in an emergency, to correct ventricular tachycardia and ventricular fibrillation.

It is also the mean arterial pressure that is carefully regulated by short-term and long-term regulatory and compensatory mechanisms. The mean arterial pressure is a time-weighted average of pressure values in large systemic arteries during the cardiac cycle.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.s people age, they get plaque buildup inside the blood vessels, and the flexible walls of the arteries become stiff. Now, when the heart squeezes and pushes the blood out, the blood vessels can't expand like they used to do and sustain higher pressure.
