What is the difference between VF and VT?

VF and pulseless VT are both shockable rhythms. The AED cannot tell if the individual has a pulse or not….(Irregular Wide Complex Tachycardia)

What is the difference between tachycardia and ventricular tachycardia?

Tachycardia is a very fast heart rate of more than 100 beats per minute. The many forms of tachycardia depend on where the fast heart rate begins. If it begins in the ventricles, it is called ventricular tachycardia. If it begins above the ventricles, it is called supraventricular tachycardia.

How can you tell the difference between V fib and V Tach?

Vfib is rapid totally incoordinate contraction of ventricular fibers; the EKG shows chaotic electrical activity and clinically the patient has no pulse. Vtach is defined by QRS greater than or equal to . 12 secs and a rate of greater than or equal to 100 beats per minute.

What is ventricular tachycardia or ventricular fibrillation?

Ventricular tachycardia (VT or V-tach) is a type of abnormal heart rhythm, or arrhythmia. It occurs when the lower chamber of the heart beats too fast to pump well and the body doesn’t receive enough oxygenated blood.

What is the difference between tachycardia and fibrillation?

The main difference between Tachycardia and Atrial Fibrillation is that Tachycardia is a condition where the normal electrical impulses that control the rate of your heart’s pumping action are disrupted whereas atrial fibrillation is a quivering or irregular heartbeat that can lead to blood clots,…

What are the different types of ventricular tachycardia?

There are three main types of ventricular tachyarrhythmias: ventricular fibrillation, monomorphic ventricular tachycardia, and polymorphic ventricular tachycardia. Each one is associated with a high mortality rate. Symptoms include chest pain, palpations, hemodynamic collapse, and end-organ damage.

What medications cause ventricular tachycardia?

Medications. Certain drugs can cause your heart to beat faster. Drugs that extend QT interval such as class III antiarrhythmics and levofloxacin can cause ventricular tachycardia. Other drugs such as halothane that decrease the conduction velocity may also cause your heart to beat faster.

What are risk factors for ventricular fibrillation (VF)?

Ventricular fibrillation is a common cause of sudden cardiac death. Risk factors for ventricular fibrillation include previous experience of ventricular fibrillation, a previous heart attack, cardiomyopathy, cocaine or methamphetamine use, congenital heart failure, along with electrocution and other injuries that damage the heart .
