Which is the medication of choice for chest pain and Vtach VFib?
Amiodarone is a class III antiarrhythmic agent indicated for the management of life-threatening recurrent VF. Amiodarone may be administered intravenously or orally.
What is the first treatment 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.
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.
How is Vtach ACLS treated?
Apply defibrillator pads (or paddles) and shock the patient with 120-200 Joules on a biphasic defibrillator or 360 Joules using a monophasic. Continue High Quality CPR for 2 minutes (while others are attempting to establish IV or IO access).
Why do you give epinephrine for ventricular fibrillation?
Medication Summary The theoretical benefit of vasopressor medicines, such as epinephrine and vasopressin, is that they increase coronary perfusion pressure. Coronary perfusion pressure is the difference between aortic and right atrial pressure during the relaxation phase of CPR, and it determines myocardial blood flow.
What is amiodarone 400mg used for?
Amiodarone is used to treat and prevent certain types of serious, life-threatening ventricular arrhythmias (a certain type of abnormal heart rhythm when other medications did not help or could not be tolerated. Amiodarone is in a class of medications called antiarrhythmics.
Can you take amiodarone and metoprolol together?
Interactions between your drugs Using amiodarone together with metoprolol may lead to increased side effects. Contact your doctor if you experience a reduced heart rate, dizziness, fainting, or headaches. You may need a dose adjustment or need your blood pressure checked more often if you use both medications.
Is V fib pulseless?
Ventricular fibrillation, also known as VFib, and pulseless ventricular tachycardia, also known as V-tach, are lethal dysrhythmias that do not produce a pulse. VFib is the most common initial dysrhythmia in cardiac arrest patients and will regress to asystole if it isn’t treated in a short amount of time.
What are the two main ACLS medications used for ventricular fibrillation and pulseless ventricular tachycardia?
A vasopressor is a medication that produces vasoconstriction and a rise in blood pressure. The vasopressor that is used for the treatment of VF/Pulseless VT is epinephrine. Epinephrine is primarily used for its vasoconstrictive effects.
How does amiodarone work in V fib?
Acute amiodarone therapy results in a use-dependent inhibition of inward sodium (Vaughan-Williams class I effect) and inward calcium currents (Vaughan-Williams class IV effect),11 as well as a non-competitive alpha- and beta-blockade effect (Vaughan-Williams class II effect).
What meds can I use to control my a fib?
A List of Common AFib Medications Heart rate medications. If your heart rate is too fast, this means that your heart doesn’t work as efficiently as it should. Heart rhythm medications. AFib is an electrical problem. Blood thinners. There are different types of blood thinners. Side effects. Different medications for AFib have different potential side effects. Talk to your doctor.
Does V fib have a pulse?
A person in ventricular tachycardia may have a pulse (or might not!) whereas a person in ventricular fibrillation never has a pulse. A monitor is needed to identify the heart rhythmn.
What causes V fib after a cardiac catheterization?
Causes of ventricular fibrillation. V-fib can have several root causes, including: Insufficient blood flow to the heart muscle. Damage to the heart muscle (from a heart attack, for example) Cardiomyopathy. Problems with the aorta. Drug toxicity.
What are the medications for ventricular fibrillation?
Doctors use various anti-arrhythmic drugs for emergency or long-term treatment of ventricular fibrillation. A class of medications called beta blockers is commonly used in people at risk of ventricular fibrillation or sudden cardiac arrest.
