How do you treat ventricular tachycardia?
Treatment for ventricular tachycardia may include medication, a shock to the heart (cardioversion), catheter procedures or surgery to slow the fast heart rate and reset the heart rhythm.Feb 2, 2022
Why do you give epinephrine for ventricular fibrillation?
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.Jan 12, 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
How many joules should a defibrillator be?
If the defibrillator is biphasic, the manufacturer recommended joules should be selected (usually 120 to 200 joules). If the amount is unknown, use the maximum available and subsequent doses should be equivalent, and possibly higher. 1.
What is the most important intervention for cardiac arrest?
Irrespective of the cause of cardiac arrest, the most important interventions are early recognition and calling for help—including appropriate management of the deteriorating patient—early defibrillation, high-quality cardiopulmonary resuscitation (CPR) with minimal interruption of chest compressions, and treatment of reversible causes. 6
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).
What is the most important algorithm for resuscitation?
Ventricular fibrillation falls under the ACLS Adult Cardiac Arrest Algorithm and is the most important algorithm to know for adult resuscitation. 1 Ventricular fibrillation treatment starts with early and effective CPR with the application of oxygen and monitor/defibrillator placement. Keeping the brain, heart, ...
How to cure atrial flutter?
Currently, atrial flutter is successfully "cured" by radiofrequency catheter ablation; but treatment to restore atrial fibrillation to sinus rhythm has been the traditional use of medications and external cardioversion.
What is a biventricular pacemaker?
Biventricular Pace Maker. The U.S. Food and Drug Administration (FDA) recently approved the first of a new type of pacemaker that paces both ventricles of the heart to coordinate their contractions and improve their pumping ability.
What is radiofrequency ablation?
A technique pioneered at UCSF, radiofrequency catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias, providing relief for patients who may not have responded well to medications, or who would rather not or can't take medications.
How many joules does external cardioversion have?
External cardioversion is delivery of high energy shocks of 50 to 300 joules through two defibrillator pads attached to the chest. In some cases, external cardioversion has failed because the electrical current has to first travel through chest muscle and skeletal structures before reaching the heart.
When was internal cardioversion developed?
Internal cardioversion for conversion of atrial fibrillation and atrial flutter to a normal sinus rhythm was developed here at UCSF Medical Center in 1991. Internal cardioversion is low energy electrical shock (1 to 10 joules) delivered internally in the heart through two catheters inserted in a vein in the groin and a small electrode pad applied to the chest. This procedure is performed in the electrophysiology lab by our electrophysiologist.
What is an implantable cardioverter?
An implantable cardioverter defibrillator is a device for people who are prone to life-threatening rapid heart rhythms. It is slightly larger than a pacemaker and usually is implanted beneath the skin below the collarbone. It is connected to a defibrillation/pace wire (s) positioned inside the heart via a vein. It has the capability of delivering an electric shock to the heart when it determines the heart rate is too fast. It also is capable of pacing or stimulating the heart when it is going too slow.
What is a pacemaker?
The U.S. Food and Drug Administration (FDA) recently approved the first of a new type of pacemaker that paces both ventricles of the heart to coordinate their contractions and improve their pumping ability. According to the test results presented to the FDA, cardiac resynchronization therapy (CRT): 1 Increases the amount of daily activities patient can perform without the symptoms of heart failure 2 Extends the exercise capacity of heart failure patients as measured by the distance they can walk in 6 minutes 3 Improves the overall quality of life as judged by standard measurements 4 Promotes changes in heart anatomy to improve cardiac function 5 Reduces the number of days patients spend in the hospital and the total number of hospitalizations
What is the drug of choice for ventricular fibrillation?
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 is the treatment of choice for ventricular fibrillation quizlet?
Ventricular fibrillation is primarily treated with defibrillation. If three successive shocks and epinephrine have been given, the next line agent would be an antiarrhythmic, such as lidocaine or amiodarone.
What immediate steps must be taken if the patient has pulseless ventricular tachycardia or ventricular fibrillation?
Pulseless VT, in contrast to other unstable VT rhythms, is treated with immediate defibrillation. High-dose unsynchronized energy should be used. The initial shock dose on a biphasic defibrillator is 150-200 J, followed by an equal or higher shock dose for subsequent shocks
When should you shock a patient?
Electrical cardioversion is used when the patient has a pulse but is either unstable, or chemical cardioversion has failed or is unlikely to be successful. These scenarios may be associated with chest pain, pulmonary oedema, syncope or hypotension
What are the 3 priorities of life support?
There are three basic C’s to remember—check, call, and care. When it comes to first aid, there are three P’s to remember—preserve life, prevent deterioration, and promote recovery

The following are only practice questions and answers; therefore they will not be seen on either our BLS Certification or BLS Recertification exams.
What is full form of BLS?
Basic Life Support, or BLS, generally refers to the type of care that first-responders, healthcare providers and public safety professionals provide to anyone who is experiencing cardiac arrest, respiratory distress or an obstructed airway.
