A forceful apex beat indicates left ventricular pressure overload, while a right ventricular heave suggests right ventricular pressure overload. Other signs provide evidence for specific causes of pressure overload. Hypertension is diagnosed by sphygmomanometry. A narrow pulse pressure is a sign of aortic stenosis.
If blood pressure decreases, the heart beats faster in an attempt to raise it. This is called reflex tachycardia. This can happen in response to a decrease in blood volume (through dehydration or bleeding), or an unexpected change in blood flow. The most common cause of the latter is orthostatic hypotension (also called postural hypotension).

In hypertensive patients, a high pulse pressure can often be an indicator of conduit artery stiffness (stiffness of the major arteries). [13] When the arterial walls are stiffer (less compliant), the heart has to beat harder to overcome the resistance from the stiff arteries, resulting in an increased pulse pressure. [14]
POTS patients experience an increase in heart rate within a few minutes of standing or sitting up. This makes it different from other conditions that generally cause a fast heart rate.
High blood pressure, or hypertension, puts additional strain on the heart, blood vessels and other organs. It can increase the risk of heart attacks and stroke, as well as the likes of heart and ...
