However, if your heart does not go back into normal rhythm, V-Tach can lead to the deadly ventricular rhythm called
Ventricular Fibrillation. If you do not receive immediate medical attention (CPR, De
fibrillation) this rhythm is always fatal. Your heart shakes and moves around like a bag of worms instead of beating. Most of the time, with a structurally normal heart, no heart disease or blockage, V-Tach will not happen. That is what your doctor is trying to say.
