Watson's water hammer pulse is the medical sign which describes a pulse that is bounding and forceful,[1] or, in other words, rapidly increasing and subsequently collapsing,[2] as if it were the hitting of a water hammer that was causing the pulse.
This is associated with increased stroke volume of the left ventricle and decrease in the peripheral resistance leading to the widened pulse pressure of aortic regurgitation.

Eponym
"Watson's water hammer pulse" and "Corrigan's pulse" refer to similar observations. However, the former usually refers to measurement of a pulse on a limb, while the latter refers to measurement of the pulse of the carotid artery.[1]
- "Corrigan's pulse" is named for Sir Dominic Corrigan, the Irish physician, who characterized it in 1832.[3][4]
- "Watson's water hammer pulse" is named for Thomas Watson, who characterized it in 1844.[1]
Observation
To feel a water hammer pulse: with the patient reclining, the examiner raises the patient's arm vertically upwards. The examiner grasps the muscular part of the patient's forearm. A water hammer pulse is felt as a tapping impulse which is transmitted through the bulk of the muscles. This happens because the blood that is pumped to the arm during systole is emptied very quickly due to the gravity effect on the raised arm. This results in the artery emptying back into the heart during diastole, therefore causing a palpable pulse.
Causes
Water hammer pulse is commonly found when a patient has in aortic regurgitation. A more comprehensive list of causes follows:
1. Physiological
2. Cardiac lesions
- Aortic regurgitation
- Patent ductus arteriosus
- Systolic hypertension
- Bradycardia
- Aortopulmonary window
- Rupture of sinus of Valsalva into heart chambers
3. Syndromes or High output states
- Anemia
- Cor pulmonale
- Cirrhosis of liver
- Beriberi
- Thyrotoxicosis
- Arteriovenous fistula
- Paget's disease
4. Other causes

- S3:左心機能が落ちれば聴取される
- 拡張期逆流性雑音 = 拡張期灌水様雑音 = blowing murmur in early diastole along the left sternal border
- 最強点:3LSB。
- 持続時間:軽症・急性型では持続時間は短い。
- 音量は一定かだんだん小さくなる(decrescendo)
- 重症度と音量は相関しないが、雑音の持続時間は参考になる。軽症では拡張期の初期にのみ吹くような(blowing)音が聴取される。重症になるにつれだんだん伸びていき、しまいには拡張期全体に聴取されるようになり、音は粗な音である(rougher)。
(参考6)
:::持続時間は重症度を反映しないが、軽度ARでは持続時間は短い(なぜ?)。また急性ARでも短いが、これは拡張期にすぐに大動脈と左心室の圧が均衡するからである(圧較差が小さいということか?)。(up2date)
- Austin Flint murmur:拡張期中期に低音を心尖で聴取。拡張期に大動脈弁から逆流してくる血液の乱流により、僧帽弁前尖が下方に押し下げられMS様の雑音を生じる。Austin Flint雑音はMSと違ってopening snapがなく、収縮期前期の雑音の増強がない。(PHD.214)
特徴的な身体所見 PHD.215
- 末梢の症状にトラウベ徴候、デュロジェ雑音、コリガン脈(water hammer pulse)があるが、これらは慢性ARでは特徴的だが、急性ARではほとんど見られない。急性ARではstroke volume and diastolic filling volumeが増えないためである(uptodate)
