Pulseless ventricular tachycardia is life-threatening. If left untreated, the heart attack can lead to death.
Tachycardia is when the heart beats more than 100 times a minute.
The ventricle is the control center of the heart center.
The term "pulseless" refers to the absence of a pulse, which means that normal blood flow is nonexistent during each heartbeat. That's because the ventricles pump blood incredibly fast, and that speed doesn't match the speed of the atria.
When you combine these terms, you'll understand that the heart's great ventricles temporarily pump blood quickly when the pulseless ventricular tachycardia does not have the desired effect.
