What is refractory ventricular?
• Refractory VF is ventricular fibrillation that is thought to be “shock resistant” to standard cardioversion, due to ongoing myocardial ischemia fostering ongoing electrical instability. • This is the concept of cardiac “Electrical Storm”, where the myocardium is extremely resistant to stabilization.
How is refractory V fib treated?
Epinephrine is the first drug given and may be repeated every 3 to 5 minutes. If epinephrine is not effective, the next medication in the algorithm is amiodarone 300 mg. Defibrillation and medication are given in an alternating fashion between cycles of 2 minutes of high-quality CPR.
What does refractory mean in ACLS?
Background Information: Refractory ventricular fibrillation (RVF) is a complication of cardiac arrest defined as ventricular fibrillation (VF) that does not respond to three or more standard defibrillation attempts.1,2 Patients with RVF during their cardiac arrest have a mortality of up … CardiovascularResuscitation.
What drug is indicated for patients with refractory ventricular fibrillation?
The guidelines recommend administration of amiodarone for sustained ventricular fibrillation (Vf) and ventricular tachycardia (VT) refractory to CPR, defibrillation, and vasopressor in out-of-hospital cardiac arrest. Lidocaine is recommended as an alternative to amiodarone.
Do you do CPR for V fib?
The first response to V-fib may be CPR. This will keep your blood moving to important organs. Defibrillation. This is an electrical shock that is delivered to your chest wall to restore normal rhythm.
What does refractory to treatment mean?
The word “refractory” in general use means stubborn or intractable, and in medicine it is specifically applied to disease that does not respond to treatment. Refractory cancer refers to cancer that may be resistant at the beginning of treatment, or becomes resistant during treatment.
Is torsades VFIB or Vtach?
A: Torsades de pointes is a ventricular tachycardia, meaning that it is a fast heartbeat with the electrical activity from the ventricles.
Why is amiodarone used in ventricular fibrillation?
Amiodarone is a potent antiarrhythmic agent that is used to treat ventricular arrhythmias and atrial fibrillation. The drug prevents the recurrence of life-threatening ventricular arrhythmias and produces a modest reduction of sudden deaths in high-risk patients.
What medication should not be prescribed for patients with ventricular fibrillation?
Procainamide (Procanbid, Pronestyl, Pronestyl [SR]) Procainamide is a third-line drug of choice for VF. This drug is generally not recommended for VF patients, but because of its long loading time, it can be used to prevent recurrences of VF or for treatment of sustained ventricular tachycardia (VT).
Does V tach have a pulse?
V-tach occurs when your pulse rate is more than 100 beats per minute, and you have at least three irregular heartbeats, or arrhythmias, in a row. Besides palpitations, V-tach can cause symptoms like: Chest pain.
What is refractory ventricular fibrillation (RVF)?
Refractory ventricular fibrillation (RVF) is a life-threatening cardiac arrhythmia unresponsive to traditional methods of defibrillation and advanced cardiovascular life support (ACLS).
What is refractory ventricular tachycardia (electrical storm)?
Refractory ventricular tachycardia, also known as “electrical storm,” is defined as at least two or more separate ventricular tachycardia (VT) or fibrillation (VF) episodes requiring intervention in a 24-hour period (1, 2, 3). So what to do? Start with the basics.
Can RVF be converted to a perfusing rhythm?
Given the difficulty in converting RVF to a perfusing rhythm, here are a few strategies beyond the standard therapy to add to your toolbox. Refractory ventricular fibrillation (RVF) is a life-threatening cardiac arrhythmia unresponsive to traditional methods of defibrillation and advanced cardiovascular life support (ACLS).
What are the causes of VF/VT?
A culprit lesion in the coronary vasculature can be the cause for VF/VT. Although the idea of VF or VT that is resistant to electricity is the stuff that emergency physicians’ nightmares are made of, there are concrete steps and medications to administer in order to increase the likelihood of returning to a normal perfusion pattern.
