Blood pressure is defined as lateral pressure exerted by contained column of blood on the vessel wall when heart pumps. Normal blood pressure is 120/80mm Hg. Blood pressure is expressed in different terms, namely Systolic pressure : this is maximum pressure exerted in the arteries during systole of heart. It reflects stroke volume. Diastolic pressure : this is the minimum pressure present in the arteries during diastole of heart.
It reflects peripheral vascular resistance. Pulse pressure: this is the difference between the systolic and diastolic pressure. A high pulse pressure indicates risk of coronary artery disease. Causes of systolic Hypertension with wide pulse pressure decreased vascular compliance (arteriosclerosis) Increased cardiac output Aortic regurgitation Thyrotoxicosis Hyperkinetic heart syndrome fever Arteriovenous fistula patent ductus arteriosus Mean arterial…
