What is a water hammer pulse?
Watson's Water Hammer Pulse is a characteristic medical feature described by Thomas Watson, M.D. in 1844. The water hammer pulse is a pulse that pulsates powerfully, similar to the nature of the water hammer. This hyperdynamic pulse occurs when the increased amount of blood is drawn with each stroke of the left ventricle, the largest chamber of the heart. There is also reduced blood flow resistance, leading to the expansion of the range between the highest and the lowest number of blood pressure reading, called pulse pressure. Corrigan's pulse, named for Sir Dominic Corrigan, M.D., concerns a water hammer pulse that is detected in carotid artery, while Watson's water pulse pulse affects the water hammer pulse detected peripherally in the arm or leg.
PULS is a rhythmic pulse of blood flow due to heart engraving. Pulse can be felt in many places on the human body. Common sites for pulse control include the throat, on the Thzápěstí on the inside of the elbow, behind the knee and near the ankle. Can be toofound that the assessment of heart rhythms directly using a stethoscope. Both pulse frequencies and quality reveal the basic state of the heart and blood vessels.
systolic and diastolic values form numeric boundaries of blood pressure. They represent the opposite ends of the heart cycle and the highest and lowest blood pressure levels for the individual. The pulse pressure is an indicator of the force that the heart generates every time it withdraws. In healthy adults, the pulse pressure in a sitting position is approximately 40, but may increase to 100 during exercise. Some studies suggest that pulse pressure can be a better prognostic indicator of clinical result than systolic or diastolic blood pressure itself.
Water H is associated with many symptoms of Pulse, the most common are muscle weakness and fatigue. Other related symptoms include shortness of breath, swelling of the lower limb and headache. The patient may have chest pain and palpitations. WITHRdeční arrhythmia, irregular heart rhythm, may occur as a result of impaired power lines in the heart chambers.
The water hammer pulse is most often associated with the leakage of the aortic valve. Aortic valve is a valve that usually keeps blood that has been exhausted from the heart to flow back into the heart. Aortic regurgitation or leak occurs when the valve does not close properly, allowing blood to penetrate backwards. As a result, the left ventricle must draw more blood than usual, with progressive expansion due to additional workload. Symptoms of aortic regurgitation may range from mild to heavy, some patients have no symptoms for years.
Some physiological conditions may cause a water hammer, such as pregnancy, fever and extreme anxiety. Other health conditions may cause a widespread pulse pressure, including anemia, hypertension and liver cirrhosis. It may also occur in the hyperactive thyroid gland. An abnormal connection between arteries and veins,called fistula, they can also create this pulse.
