Ventricular tachycardia (v-tach) typically responds well to defibrillation. Most patients with this rhythm are unconscious and pulseless and defibrillation is needed to “reset” the heart so that the primary pacemaker (usually the Sinoatrial Node) can take over.

Considering this, what are the 3 shockable rhythms?

Shockable rhythms include pulseless ventricular tachycardia or ventricular fibrillation. Nonshockable rhythms include pulseless electrical activity or asystole.

Beside above, can you shock in V fib? Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks, also referred to as defibrillation. EKG synchronization is not possible with VF, since it is a chaotic, disorganized rhythm.

Also Know, how do you shock Vtach?

Apply defibrillator pads (or paddles) and shock the patient with 120-200 Joules on a biphasic defibrillator or 360 Joules using a monophasic. 4. Continue high-quality CPR for 2 minutes (while others are attempting to establish IV or IO access).

Do you defibrillate ventricular tachycardia?

Defibrillation - is the treatment for immediately life-threatening arrhythmias with which the patient does not have a pulse, ie ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Cardioversion - is any process that aims to convert an arrhythmia back to sinus rhythm.

What happens if you defibrillate a conscious person?

Using it on a person who experiences cardiac arrest—a sudden loss of heart function—may save the person's life. But even if the problem isn't cardiac arrest, using the AED is very unlikely to cause harm. These electrodes detect the heart's rhythm, which a computer then analyzes to determine if a shock is needed.

What does asystole mean?

Asystole is the most serious form of cardiac arrest and is usually irreversible. A cardiac flatline is the state of total cessation of electrical activity from the heart, which means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.

What joules do you shock at?

If the patient is in Ventricular tachycardia (VT) or ventricular fibrillation (VF) on the monitor, immediately apply the pads and shock the patient with 120-200 Joules on a biphasic defibrillator or 360 Joules on a monophasic defibrillator.

What are the 4 lethal heart rhythms?

In this course, you will learn about premature ventricular contractions, ventricular tachycardia, ventricular fibrillation, pulseless ventricular tachycardia, pulseless electrical activity, asystole, agonal rhythms, and supraventricular tachycardia.

Do you shock VT with a pulse?


Unlike defibrillation, which is used in cardiac arrest patients, synchronized cardioversion is performed on patients that still have a pulse but are hemodynamically unstable. The most common cause of sudden cardiac arrest in adults is pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF).

What is the difference between VT and VF?

VF (Figure 24) is a rapid quivering of the ventricular walls that prevents them from pumping. The ventricular motion of VF is not synchronized with atrial contractions. VT (Figure 25) is a condition in which the ventricles contract more than 100 times per minute.

How many times can you shock a patient with an AED?

If the operator has attached the AED to an adult victim who's not breathing and pulseless (in cardiac arrest), the AED will make the correct "shock" decision more than 95 of 100 times and a correct "no shock indicated" decision more than 98 of 100 times.

Can you shock a flatline?

In asystole (flat line), there is no longer any effective electrical activity of the heart. That is why it makes no sense to shock someone in asystole. On television, people in flatline are shocked into a stable sinus rhythm. That just doesn't happen in real life.

What do you give for Vtach?

Is the QRS complex wide or narrow?
Patient Treatment
The patient's QRS is narrow and rhythm is regular. Try vagal maneuvers. Give adenosine 6 mg rapid IV push. If patient does not convert, give adenosine 12 mg rapid IV push. May repeat 12 mg dose of adenosine once.

When should you avoid synchronized shock?


For cases where electrical shock is needed, if the patient is unstable, and you can see a QRS-t complex use (LOW ENERGY) synchronized cardioversion. If the patient is pulseless, or if the patient is unstable and the defibrillator will not synchronize, use (HIGH ENERGY) unsynchronized cardioversion (defibrillation).

Do you give EPI for V tach?

Currently, the ACLS protocol for v fib and pulseless v tach recommends that epinephrine be given after the second defibrillation.

Why can you not shock asystole?

PEA is treated much like asystole. It is not a shockable rhythm because the electrical system in the heart is actually working properly. Shocking the patient is done to 'reset' the heart's rhythm, but the problem in PEA isn't in the conduction of electrical stimuli in the heart.

Can you be conscious in VF?

When VF occurs, the two chambers in the lower portion of your heart aren't able to pump hard enough to move blood through your body. As a result, blood can't get to your vital organs. Fainting or losing consciousness are the most common symptoms of VF, earlier symptoms include: chest pain.

What do you do for Vtach ACLS?

Stable patients with tachycardia with a palpable pulse can be treated with more conservative measures first.
  1. Attempt vagal maneuvers.
  2. If unsuccessful, administer adenosine 6 mg IV bolus followed by a rapid normal saline flush.
  3. If unsuccessful, administer adenosine 12 mg IV bolus followed by a rapid normal saline flush.

When should you not use an AED?


You should not use an automated external defibrillator (AED) in the following situations:
  1. Do not use AED if victim is lying in water.
  2. Do not use AED if chest is covered with sweat or water.
  3. Do not put an AED pad over a medication patch.
  4. Do not place AED pad over a pacemaker (hard lump under chest skin).

What causes v tach?

V-tach is caused by a disruption in the normal electrical impulses that control the rate of your ventricles' pumping action. Many things can cause or contribute to problems with the heart's electrical system. These include: Lack of oxygen to the heart due to tissue damage from heart disease.
