Collapsing pulse (also called water-hammer pulse) is a classic bedside finding, especially in aortic regurgitation and high-output states like anemia or thyrotoxicosis. . Don’t confuse it with bounding pulse (which may be strong but not collapsing).Don’t test in atrial fibrillation, the irregular rhythm makes it hard to appreciate. Ensure patient’s arm is relaxed as muscle tension dampens the collapse. . . #doctor #drshujat #medicalstudent #medstudent #mbbs #medical #cardio #cardiologist | Dr M
