VF and pulseless VT are shockable rhythms and treated in similar fashion. Asystole and PEA are also included in the cardiac arrest algorithm but are non-shockable rhythms. Ventricular fibrillation and pulseless ventricular tachycardia are treated using the left branch of the cardiac arrest arrest algorithm.

Consequently, what are the 3 shockable rhythms?

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

Similarly, is SVT shockable? The shock that is delivered for SVT is synchronized to occur at a precise time during the “R” wave on the EKG, so as to avoid the vulnerable refractory period which could cause ventricular fibrillation. This is simply accomplished by pressing the “sync” button that is found on all defibrillators.

Also know, do you shock pulseless v tach?

In other pulseless rhythms, such as ventricular fibrillation and pulseless ventricular tachycardia, shocks are advised, but defibrillation will do nothing to help the patient in PEA. The primary treatment is to find the underlying cause of the arrest.

How is pulseless ventricular tachycardia treated?

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.

Does asystole mean death?

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.

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 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 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.

Do you give EPI for asystole?

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. Rhythm checks should be performed after 2 minutes (5 cycles) of CPR.

Which rhythms do you Cardiovert?

The most common irregular heart rhythms that require cardioversion include atrial fibrillation and atrial flutter. Life-saving cardioversion may be used to treat ventricular tachycardia (a rapid, life-threatening rhythm originating from the lower chambers of the heart).

Can a person be breathing without a pulse?

It is entirely possible to be breathing, walking and talking with no pulse. Under normal circumstances (no LVAD) a person in cardiac arrest will not be breathing. With no blood circulating the victim will be unconscious in seconds, breathing will stop almost as rapidly.

What happens if you shock asystole?

Medically, a “flat-line” is known as asystole, meaning no (heart) contraction. It might seem common sense that if there is no contraction you might want to contract it with a shock. The truth about why this will never “restart” the heart lies in how the heart creates its life giving beat.

What does pulseless VT look like?

The pulseless ventricular tachycardia rhythm is primarily identified by several criteria. First, the rate is usually greater than 180 beats per minute, and the rhythm generally has a very wide QRS complex. Second, the patient will be pulseless. And third, the rhythm originates in the ventricles.

What does VF and VT stand for?

Ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) are life-threatening cardiac rhythms that result in ineffective ventricular contractions. VF (Figure 24) is a rapid quivering of the ventricular walls that prevents them from pumping.

What is the drug of choice for ventricular tachycardia?

For the emergency treatment of sustained, hemodynamically stable ventricular tachycardia, antiarrhythmic drugs are the therapy of choice. Mostly class I antiarrhythmic drugs, such as lidocaine or ajmaline, are preferred.

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.

Why are VT and VF shockable?

The treatment of (VF and pulseless VT) Ventricular Fibrillation and Pulseless Ventricular Tachycardia is included in the Cardiac Arrest Algorithm. VF and pulseless VT are shockable rhythms and treated in similar fashion. Asystole and PEA are also included in the cardiac arrest algorithm but are non-shockable rhythms.

How is pulseless electrical activity treated?

When treating PEA, epinephrine can be given as soon as possible but its administration should not delay the initiation or continuation of CPR. High-quality CPR should be administered while giving epinephrine, and after the initial dose, epinephrine is given every 3-5 minutes.

What rhythms do you defibrillate?

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 is the difference between asystole and pulseless electrical activity?

Pulseless electrical activity (PEA) and asystole are related cardiac rhythms in that they are both life-threatening and unshockable. Asystole is a flat-line ECG (Figure 27). PEA is one of many waveforms by ECG (including sinus rhythm) without a detectable pulse.

What's the difference between V fib and V Tach?

Ventricular tachycardia (v-tach is treated similarly to v-fib. The difference is that ventricular tachycardia continues to make the heartbeat regularly, but it goes so fast that the heart never gets a chance to fill with blood. Asystole is the term for a lack of any sort of heartbeat at all.
