Guest guest Posted March 20, 2006 Report Share Posted March 20, 2006 Is this " valsalva phenomenon " a danger on it's own, or a problem indicator? I could see the light headedness being a problem if you fell over, tripped, passed out and hit the the ground hard, but is it also a direct problem indicator? - Lockhart Hilo, Hawaii USA ----- Original Message ----- From: Ralph Giarnella <<<From your description of events it appears that you may have experienced the effects of a Valsalva phenomenon. A valsalva phenomenon occurs when there is increased intra thoracic pressure for any reason. As a result of this there is a marked slowing of the heart This may last just a few moments and return to normal. I have seen heart rates drop to as low as 15-20 bpm during such episodes. The valsalva phenomenon does not have to occur every time there is increased intra thoracic pressure.>>> Quote Link to comment Share on other sites More sharing options...
