Anyone have supraventricular tachycardia?

I've never heard of environmental triggers for SVT. When you think about the physiology, rate control is via nervous system innervation, pressure and chemical receptors. Alterations in any of these increase of decrease a heart rate.

Some SVT are due to abnormalities in the electrical pathways in the heart and some are triggered by altered electrolyte balance so I don't think any environmental factor would be it. Perhaps stress of moving and living somewhere new as increase sympathetic activity could do it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
