What is the treatment of choice for ventricular fibrillation?
External electrical defibrillation remains the most successful treatment for ventricular fibrillation (VF). A shock is delivered to the heart to uniformly and simultaneously depolarize a critical mass of the excitable myocardium.Jun 6, 2018
What is the most effective initial intervention for ventricular fibrillation?
Ventricular Fibrillation/Pulseless Ventricular Tachycardia. The most critical interventions during the first minutes of VF or pulseless VT are immediate bystander CPR (Box 1) with minimal interruption in chest compressions and defibrillation as soon as it can be accomplished (Class I).Nov 28, 2005

Which drug is considered first line treatment for asystole or PEA?
When treating asystole, epinephrine can be given as soon as possible but its administration should not delay initiation or continuation of CPR. After the initial dose, epinephrine is given every 3-5 minutes.
What is the correct treatment protocol for asystole?
Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline). Sometimes an underlying reversible cause can be detected and treated (the so-called "Hs and Ts", an example of which is hypokalaemia).
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).
How is pulseless VT treated?
Medical treatment of pulseless VT usually is carried out along with defibrillation and includes intravenous vasopressors and antiarrhythmic drugs. 1 mg of epinephrine IV should be given every 3 to 5 minutes. Epinephrine can be replaced by vasopressin given 40 units IV once.Aug 9, 2021
When do you use adenosine vs amiodarone?
Consider adenosine only if the rhythm is regular and monomorphic. Consider antiarrhythmic infusions such as procainamide, amiodarone, or sotalol IV. Consider an expert consultation.Jul 2, 2021
Which of the following drugs is used in ventricular fibrillation?
In acute ventricular fibrillation (VF), drugs (eg, vasopressin, epinephrine, amiodarone) are used after three defibrillation attempts are performed to restore normal rhythm.Jun 6, 2018
What is the initial drug of choice for SVT treatment?
Adenosine (Adenocard) Adenosine is the first-line medical treatment for the termination of paroxysmal SVT.Apr 5, 2017
Which medication is the first-line antiarrhythmic for treatment of stable wide QRS tachycardia?
Typically, amiodarone will be the first-line drug of choice for all ventricular arrhythmias (VT, polymorphic VT, Vfib, etc.) Lidocaine can also be considered as a potential 2nd line medication but it should never be used for WCT of unknown origin.Jul 1, 2021
What is VF in cardiac arrest?
Ventricular fibrillation (VF or V-fib) is the most common initial heart rhythm in patients with out-of-hospital cardiac arrest (OHCA), and the most salvageable one . 5 In VF, the etiology of arrest is often attributed to either acute ischemia or non-ischemic arrhythmia. 8
What are the causes of VF?
The easiest way to remember the most common causes of VF are to review the reversible “Hs and Ts” in cardiac arrest. The Hs include hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, and hydrogen ions (acidosis). The Ts are tension pneumothorax, cardiac tamponade, toxins, and thrombosis (pulmonary or coronary).
How long can you live with ventricular fibrillation?
Sometimes VT can last less than 30 seconds (nonsustained) and may not cause symptoms. But VT may be a sign of more-serious heart problems. If VT lasts more than 30 seconds, it will usually lead to palpitations, dizziness or fainting.
Can stress cause ventricular fibrillation?
Stress can cause a heart attack, sudden cardiac death, heart failure, or arrhythmias (abnormal heart rhythms) in persons who may not even know they have heart disease. Lower threshold for abnormal heart rhythms including ventricular tachycardia, ventricular fibrillation, and atrial fibrillation.
Can ventricular fibrillation stop on its own?
Ventricular fibrillation seldom terminates spontaneously, since several re-entrant wavefronts, independent from each other, coexist, and the simultaneous extinction of all the circuits is unlikely.
Can you be conscious in V fib?
Defibrillators don't treat cardiac arrest. Instead, they treat ventricular fibrillation, one form of cardiac arrest. That's why they're called de-fibrillators. There's absolutely no way a patient with ventricular fibrillation could be awake; no blood flowing through the brain makes the patient unconscious.
How does amiodarone stop 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.
Does a pacemaker help ventricular fibrillation?
Use of electrical pacemakers in the treatment of ventricular tachycardia and ventricular fibrillation. Overdrive pacing may prevent certain cases of ventricular arrhythmias, and antitachycardia devices may be useful in terminating paroxysmal ventricular tachycardia.
Which of the following is the treatment of choice for torsades de pointes?
Treatment of torsade de pointes includes: isoproterenol infusion, cardiac pacing, and intravenous atropine. Intravenous magnesium sulfate, a relatively new mode of therapy for torsade de pointes, was proven to be extremely effective and is now regarded as the treatment of choice for this arrhythmia.
What is the best treatment for acute heart failure?
Interventions for acute heart failure include administering a rapid-acting diuretic, such as furosemide (Lasix), to reduce preload. Interventions also typically include placing the patient in the high-Fowler position rather than the supine position.
What is the recommended energy level for a biphasic defibrillator?
If a biphasic defibrillator is used to manage a patient with stable, monomorphic ventricular tachycardia, the recommended energy level is 100 joules. The recommended energy level for supraventricular tachycardia and atrial flutter is 50 to 100 joules. The level for atrial fibrillation is 120 to 200 joules.
What is premature atrial complex?
Premature atrial complexes are ectopic beats that are initiated by an irritable atrial focus. P waves are present, but because the ectopic focus originates the impulse outside the sinoatrial node, the premature P waves have a different configuration. Atrial flutter causes no P waves, but it causes flutter waves in a sawtoothed pattern.
How long does chest pain last?
A. Of these patients, the man, age 48, is most likely to present with crushing chest pain that lasts longer than 30 minutes. Up to 20 percent of patients with an acute myocardial infarction do not experience chest pain. Patients with diabetes mellitus are more prone to neuropathy and may not experience pain.
What causes a flutter in the heart?
Atrial flutter is usually initiated by a premature atrial complex and is the most common in patients with coronary artery disease, rheumatic heart disease, pulmonar y embolism, or chronic obstructive pulmonary disease. Elevated intracranial pressure can initiate bradycardia.
What causes sudden cardiac arrest?
A common cause of sudden cardiac arrest in adults is ventricular tachycardia that, if untreated, deteriorates into ventricular fibrillation. Supraventricular tachycardia, sinus tachycardia, and junctional tachy cardia are not causes of sudden cardiac arrest.
What are the symptoms of myocardial infarction?
Women have more atypical symptoms, such as profound fatigue and shortness of breath . Among patients older than age 85, the classic symptom of acute myocardial infarction is shortness of breath. A man, age 64, presents to the emergency department with severe dyspnea and weakness.
