As a medical professional with expertise in cardiology, I can explain that
pulseless ventricular tachycardia (VT) is a serious cardiac emergency. Ventricular tachycardia is a rapid heart rate that originates in the ventricles of the heart. When it's described as "pulseless," it means that despite the rapid electrical activity in the heart, there is no effective blood circulation to produce a detectable pulse at the wrist or neck. This is often due to the heart's inability to pump blood effectively because the rapid and chaotic electrical activity prevents the heart from filling with blood and contracting in a coordinated manner.
Pulseless VT is a type of
ventricular arrhythmia that can quickly lead to sudden cardiac arrest if not treated immediately. It requires urgent medical intervention, typically with
cardiopulmonary resuscitation (CPR) and
defibrillation, to try to restore a normal heart rhythm.
