Hi, I am new, my son has just been diagnosed with Neurocardiogenic syncope. He has had an ablation for heart arrhythmia, and so I thought his symptoms were similar, racing heart, dizziness, etc. Now that I read about pots, I wonder how it is different from NCS?? Would the fact that he had considerable trouble stablizing body temp. right after birth have any bearing? thanks for any response. Suzy
