As a medical professional with expertise in cardiology, I can explain pulseless ventricular tachycardia (PVT) as a serious and potentially life-threatening heart rhythm disturbance. It is a type of ventricular tachycardia (VT) where the heart's ventricles are beating very rapidly, but there is no effective blood circulation because the heart is not pumping blood adequately. This can lead to a lack of blood flow to the brain and other vital organs, which can cause loss of consciousness and is often a medical emergency. Pulseless ventricular tachycardia is often associated with severe underlying heart conditions, such as coronary artery disease, cardiomyopathy, or congenital heart disease. It can also occur in individuals with no known heart problems, particularly in the setting of severe electrolyte imbalances or drug toxicity. The treatment for PVT typically involves immediate medical intervention, which may include cardioversion (an electrical shock to the heart), medications to try to restore a normal heart rhythm, and addressing any underlying causes. read more >>

The pulseless ventricular tachycardia rhythm is primarily identified by several criteria. First, the rate is usually greater than 180 beats per minute and the rhythm generally has a very wide QRS complex. Second, the patient will be pulseless and third, the rhythm originates in the ventricles.read more >>
