Suppose we have 110/100 blood pressure. We do not have hypertension, right? Unfortunately, no. We have probably had heart failure.
The pulse pressure, i.e., the difference between systolic (top) and diastolic (bottom), should be about 40. We probably have a severe problem when it is lower and, more specifically, less than ¼ (a quarter) of systolic.
Attention: there is always the possibility that we have not done the pressure measurement correctly or that our sphygmomanometer has a problem; let us not “die” before our time!
In the pattern “Narrow Pulse Pressure,” we show a series of such pressures. It does not follow that this is the course of a person’s pressure! These are examples to learn to recognize Narrow Pulse Pressure.
