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.
Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.
One can hear it at the left lower sternal border. One may also hear it at the right lower sternal border (when associated with a dilated aorta). Other possible exam findings are bounding carotid and peripheral pulses. These are also known as Corrigan's pulse or Watson's water hammer pulse. Another possible finding is a widened pulse pressure.
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 ...
The pulses should be palpated, first the radial pulse commenting on rate and rhythm then the brachial pulse commenting on character and finally the carotid pulse again for character. The pulses may be: Bounding as in large pulse pressure found in aortic regurgitation or CO 2 retention.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.
De Musset's sign is a type of rhythmic bobbing of the head in synchrony with the beating of the heart, seen in severe aortic regurgitation. [1]This sign occurs as a result of blood from the aorta regurgitating into the left ventricle due to a defect in the aortic valve.
Pulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. [1] It is a sign of problems with the aorta , including aortic stenosis and aortic regurgitation , as well as hypertrophic cardiomyopathy causing subaortic stenosis.
