joiedevivre Posted May 25, 2018 Report Share Posted May 25, 2018 Like many people I received nitroglycerin under the tongue during my tilt table test, and I became weak, ill, and my heart rate increased. I know this is given to people with heart failure or reduced blood flow to the heart so their blood vessels can dilate, but what happens to a healthy person who gets it? Do they feel nothing at all, or do they get weak from over dilated blood vessels but without tachycardia? Quote Link to comment Share on other sites More sharing options...
WinterSown Posted May 25, 2018 Report Share Posted May 25, 2018 They get a bad headache. And can faint. https://www.drugs.com/answers/can-it-cause-harm-if-you-take-nitro-glycerine-404361.html Quote Link to comment Share on other sites More sharing options...
Pistol Posted May 25, 2018 Report Share Posted May 25, 2018 I believe Nitroglycerin is given to people during a TTT to mimic the same stress on the heart that occurs during being upright for a long time. I had it during my TTT and promptly passed out. I believe that this is more common in people with orthostatic intolerance, "normal" people likely will be able to recover from the nitro without passing out, but a increase in HR and drop in BP is normal.
