When I put my thumb on my radial pulse and push down and then my finger after it I can still feel a pulse even though I can closing the radial artery. Why is this? It does get much weaker but I can still feel it. Is this just the pulse coming from the ulnar artery? Is this a sign of aortic regurgitation? Or is this just something normal?
