WebConclusions: AMS and PMS elicit different cardiovascular reactions. Our results indicate that changes in the autonomic tone, probably abrupt sympathetic predominance, may cause QTc prolongation and bifid T waves. This suggests that besides stress quality and intensity, the dynamics of stress application and perception also influence repolarization. WebSudden death. The symptoms of long QT syndrome appear when the syndrome leads to Torsades de Pointes. During this arrhythmia, your heart can’t pump blood effectively. If your brain doesn’t get enough blood supply, you can faint and have a seizure. If the arrhythmia continues, sudden death will occur.
