Anxiety is your mind and bodys reaction to a perceived threat, and it activates your autonomic nervous. You could lose consciousness within seconds and die within minutes.

Ventricular tachycardia is a very rapid, but regular heartbeat of 100 beats or more a minute occurring in the lower chambers (ventricles) of the heart. It is seldom life-threatening, but the heart palpitations could indicate underlying coronary artery disease or heart valve disorders. Atrial fibrillation arrhythmias could become chronic and lead to stroke.
