There are three key signs that show ventricular tachycardia is serious, which are; a)When the ventricles are beating at a rapid rate of between 120-300 beats per minute and these beats are not coordinating with atria. b)Severe palpitations. This results from the abnormal and fast uncoordinated rhythms from the ventricles, which impairs the ability of the heart to pump blood to the brain and other parts of the body. c)When the patient becomes pulseless and unresponsive. This happens when cardiac output is reduced as a result of decreased ventricular filling from the rapid heart rate.
It can go from nothing to death. Ventricular tachycardia is a very critical condition. It can last only a few seconds and even be asymptomatic. However, if maintained, it will make one lose consciousness and lead to a cardiac arrest.
