If the patient is in VTach or VFib, this IS a shockable rhythm 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 does V tach respond to defibrillation?
Ventricular tachycardia (v-tach) typically responds well to defibrillation. This rhythm usually appears on the monitor as a wide, regular, and very rapid rhythm. Ventricular tachycardia is a poorly perfusing rhythm; patients may present with or without a pulse.
What are the treatment options for V-tach?
Treatments for V-tach include: 1 Catheter ablation. This procedure is often used when a discrete electrical pathway is responsible... 2 Medications. Anti-arrhythmic medications may prevent a fast heart rate when taken regularly. 3 Implantable cardioverter-defibrillator. If you're at risk of having a life-threatening ventricular...
How do you shock a patient with a defibrillator?
If the patient is in VTach or VFib, this IS a shockable rhythm 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). After 2 minutes of CPR, check rhythm
What are the goals of ventricular tachycardia treatment?
Treatment. The goals of ventricular tachycardia treatment are to restore your normal heart rhythm, regulate your heart rate and prevent future episodes. Treatment of V-tach depends largely on what is causing the arrhythmia and the type or severity of your ventricular tachycardia.
Do you shock a patient in V tach?
Ventricular tachycardia (v-tach) typically responds well to defibrillation. This rhythm usually appears on the monitor as a wide, regular, and very rapid rhythm.
How do you shock a V tach?
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).
Do you Cardiovert or defibrillate v tach with a pulse?
MONOMORPHIC VT WITH A PULSE Synchronized cardioversion can be performed in unstable patients with a regular monomorphic VT in the presence of a pulse. Patients with irregular or polymorphic VT should however be managed with defibrillation.
Do you give epinephrine in V tach?
Currently, the ACLS protocol for v fib and pulseless v tach recommends that epinephrine be given after the second defibrillation. Many hospitals and EMS systems, however, have been giving it earlier.
What are the 2 shockable rhythms?
The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.
How is V tach treated with pulse?
If you have ventricular tachycardia, you may be given medications called anti-arrhythmics by mouth or IV to slow the fast heart rate. Other heart medications, such as calcium channel blockers and beta blockers, may be prescribed with anti-arrhythmic drugs.
Can you Cardiovert VFIB?
VF is a unique condition in sudden cardiac arrest: a single intervention can completely reverse an otherwise lethal arrhythmia (ACLS, 2005). Cardioversion is the procedure by which an abnormally fast heart rate or cardiac arrhythmia is converted to a normal rhythm, using electricity or drugs.
Which rhythms do you Cardiovert?
An electrical cardioversion, often referred to simply as a cardioversion, is a procedure used to treat an abnormal and rapid heart rhythm (also called a cardiac arrhythmia). The most commonly treated arrhythmia is atrial fibrillation. Another rhythm commonly treated with electrical cardioversion is atrial flutter.
What are the two rhythms that are not amenable to shock?
surgical evaluation. Rhythms that are not amenable to shock include pulseless electrical activity (PEA) and asystole. In these cases, identifying primary causation, performing good CPR, and administering epinephrine are the only tools you have to resuscitate the patient.
What is ventricular tachycardia?
Ventricular tachycardia is a poorly perfusing rhythm; patients may present with or without a pulse. 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.
What is the best way to restart an arrested heart?
Along with high-quality CPR, emergency medicines and defibrillation are the only two interventions that are likely to restart the arrested heart. Defibrillation a powerful tool in the hands of the ACLS practitioner and it is important to know when to use defibrillation to reset the abnormal rhythm. Determining the underlying cause ...
Is ventricular fibrillation fine or coarse?
Ventricular fibrillation may be fine or coarse; coarse ventricular fibrillation is more likely to convert after defibrillation than fine v-fib. Fine v-fib is sometimes mistaken for asystole. As the treatments for asystole and ventricular fibrillation are different, it is important to differentiate between the two.
What is the best way to diagnose ventricular tachycardia?
A thorough physical exam, medical history and testing are required to diagnose ventricular tachycardia. Your doctor will evaluate your symptoms, perform a physical examination, and ask you about your health habits and medical history. In some cases, ventricular tachycardia may be a medical emergency that requires urgent diagnosis and treatment.
Why is scar tissue used for tachycardia?
Because scar tissue doesn't conduct electricity, it interferes with stray electrical impulses that cause some types of tachycardia. Surgery is usually used only when other treatment options don't work or when surgery is needed to treat another heart disorder.
How long does ventricular tachycardia last?
Ventricular tachycardia may go away on its own within 30 seconds (nonsustained V-tach) or last more than 30 seconds (sustained V-tach or VT ).
What is the best medication for a fast heart rate?
Other heart medications, such as calcium channel blockers and beta blockers, may be prescribed with anti-arrhythmic drugs . Implantable cardioverter-defibrillator.
Is ventricular tachycardia a medical emergency?
In some cases, ventricular tachycardia may be a medical emergency that requires urgent diagnosis and treatment. Several tests may be done to diagnose ventricular tachycardia.
Why do you need stable V-tach?
Stable V-tach should certainly be addressed to prevent the rhythm from becoming more erratic and to prevent the patient from becoming symptomatic. Anti-arhythmic medications, such as adenosine, are usually given.
What are the symptoms of unstable V-tach?
In unstable V-tach, the patient will present with symptoms. Mental symptoms, such as confusion or loss of consciousness, may be the first changes noted. Without quick treatment, complete hemodynamic collapse is possible, which could lead to the need for CPR and emergency treatments.
What is the rate of heartbeat in a patient with ventricular tachycardia?
Tachycardia usually refers to any heart rhythm over 120 beats per minute, but emergency treatments are usually considered when the heart rate gets to 150 beats per minute or more.
How to manage tachycardia?
Prior to this point, the tachycardia can usually be managed by attending physicians or by family physicians through medication changes. If you’re caring for a patient in your hospital or clinic who has a fast heart rhythm, you must first determine what the EKG is showing and whether your patient is stable or unstable.
Is V-tach stable?
When V-tach is described as being stable, it occurs with very few if any symptoms. The patient will still be able to talk and generally function and may even have mostly normal vital signs other than heart rate.
Can ventricular tachycardia be caused by medication?
Many conditions, diseases and even medications can cause ventricular tachycardia, but not all episodes of tachycardia may be immediately serious. For example, a certain medication may simply need to be stopped, or the root cause of a disease may need to be addressed to get the heart back to functioning correctly.
What is V tach?
The patient has V Tach (Ventricular Tachycardia) with a pulse. After amiodarone is given the patient’s blood pressure drops and the patient becomes unstable. The patient is still awake, so cardioversion would be very painful and these physicians would need to get anesthesia to sedate the patient. I know – that anesthesia requirement is a bad policy and completely unnecessary for the safety of the patient, but it is politics in that facility. However, sedation for emergency cardioversion is very important.
Can you use epinephrine for V tach?
Do not use epinephrine for V Tach without discussing it with your medical director and obtaining permissions, assuming you work some place where the medical director has the authority. If you are a doctor, discuss this with cardiology before using it.
What is a Ventricular Arrhythmia (VTACH or VFIB)?
Ventricular arrhythmias are those originating from the ventricles. Since the ventricles are responsible for pumping blood to the lungs and throughout the body, ventricular arrhythmias are often deadly.
What Causes Ventricular Arrhythmias?
Ventricular arrhythmias are usually caused by coronary artery disease (CAD). Any lack of blood flow (i.e. a heart attack) will cause ventricular cells to be deprived of oxygen. When the cardiac myocytes become hypoxic, they become irritable and prone to firing when they shouldn’t, which leads to PVCs, VTACH, and even VFIB.
IDENTIFYING VTACH
VTACH is a tachycardic rhythm originating within the ventricles. This produces very fast heart rates which may or may not be perfusing.
MONOMORPHIC VTACH
Monomorphic VTACH originates from the same ventricular focus. This means that the same ventricular cells or region of cells are functioning as the pacemaker for this rhythm.
POLYMORPHIC VTACH
Polymorphic VTACH originates from multiple different ventricular foci.
QT Prolongation
QT prolongation is the main cause of Torsades and is defined when the QT interval is >440ms in men and >460ms in women.
IDENTIFYING VFIB
VFIB is similar to polymorphic VTACH, but on a much wider scale. Essentially, all of the ventricular cells are irritable and it produces a disorganized chaotic arrhythmia that does not perfuse the body and is a CODE BLUE.
