Watson's water hammer pulse, also known as Corrigan's pulse or collapsing pulse, is the medical sign (seen in aortic regurgitation) which describes a pulse that is bounding and forceful, [1] rapidly increasing and subsequently collapsing, [2] as if it were the sound of a water hammer that was causing the pulse.
The heartbeat may feel hard, fast, or uneven in their chest. [1] [2] Symptoms include a very fast or irregular heartbeat. Palpitations are a sensory symptom. [1] They are often described as a skipped beat, a rapid flutter, or a pounding in the chest or neck. [1] [2]
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
These wave forms may be altered by certain medical conditions; therefore, this is not always an accurate way to differentiate the JVP from the carotid pulse. The carotid artery only has one beat in the cardiac cycle. non-palpable – the JVP cannot be palpated. If one feels a pulse in the neck, it is generally the common carotid artery.
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
Note that the P wave that disrupts the pause (indicated by the dashed arrow) does not look like the previous (normal) P waves – this last P wave is arising from a different part of the atrium, representing an escape rhythm. A slow rhythm (less than 60 beats/min) is labelled bradycardia. This may be caused by a slowed signal from the sinus ...
This wave of activity, called a cortical spreading depression, follows a particular pattern across the brain and can create a few different patterns of light in your vision. For example, the Mayo ...
The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds. [1] Narrowed pulse pressure might also be observed. The concept was developed in 1935 by Claude Beck, a resident and later Professor of Cardiovascular Surgery at Case Western Reserve University. [2] [3]
