ANAESTHETIC IMPLICATIONS OF THE CARDIAC IMPLANTABLE ELECTRONIC DEVICES (CIEDs)
Explanation:
Pulse pressure: it is the difference between systolic and diastolic pressure. A rise in systolic pressure or a fall in SVR will increase the gap.
Normal value ~30 to 40 mmHg.
A widened (or larger) pulse pressure occurs with several diseases, including
- Aortic regurgitation,
- Aortic sclerosis (both heart valve conditions),
- Severe iron deficiency anaemia (reduced blood viscosity),
- Arteriosclerosis (less compliant arteries, elderly), and
- Hyperthyroidism (increased systolic pressure).
In the majority of these cases, systolic pressures increase while diastolic pressures remain near normal.
In aortic regurgitation, the aortic valve insufficiency results in a backward, or regurgitant flow of blood from the aorta back into the left ventricle, so that blood ejected during systole returns during diastole. This condition leads to an increase in the systolic pressure and a decrease in the diastolic pressure, which results in increased pulse pressure.
In aortic stenosis, there is a narrowing of the aortic valve, which interferes with the ejection of blood from the left ventricle into the aorta, which results in a decrease in stroke volume and a subsequent decrease in pulse pressure.
