Consider sedation prior to cardioversion but do not delay treatment. If the rhythm is regular with narrow complexes, consider adenosine 6 mg IV rapid push. If the patient is stable, measure the QRS. If QRS is wider than 0.12 seconds, establish IV access and obtain a 12 lead ECG. Consider adenosine only if the rhythm is regular and …Ventricular fibrillation, or VF, is considered the most serious abnormal heart rhythm. VF is extremely dangerous and can lead to sudden cardiac death. Without …Synchronized cardioversion is a procedure similar to electrical defibrillation in that a transthoracic electrical current is applied to the anterior chest to terminate a life-threatening or unstable tachycardic arrhythmia. Unlike defibrillation, which is used in cardiac arrest patients, synchronized cardioversion is performed on patients that still have a …V-tach can be life-threatening if it's sustained (lasting more than 30 seconds). VFib. A fast, abnormal rhythm starts in the ventricles and prevents blood from being pumped throughout the body. Ventricle walls twitch or quiver uncontrollably and irregularly. VFib is always life-threatening, causing sudden cardiac arrest. Treatment. For the purposes of ACLS, atrial flutter is treated the same as atrial fibrillation. When atrial flutter produces hemodynamic instability and serious signs and symptoms, it is treated using ACLS protocol. For the patient with unstable tachycardia due to this tachyarrhythmia (atrial flutter), immediate cardioversion is recommended.

Summary. Ventricular fibrillation, or VFib or VF, is a dangerous arrhythmia that causes the heart's lower chambers (ventricles) to erratically quiver instead of pumping blood as they should. VFib results in sudden cardiac arrest and requires emergent defibrillation (electric shock) to restore the heart's normal rhythm.Pulseless ventricular tachycardia is a medical emergency. Due to rapid ventricular contractions, the ventricular filling decreases markedly, leading to a dramatic decrease in cardiac output. As a result, a pulse is absent.

Pulseless ventricular tachycardia (VT) and Ventricular fibrillation (VF) are life-threatening cardiac rhythms that result in ineffective ventricular contractions. The ventricular motion of VF is not synchronized with atrial contractions. VT or VTach (Figure 25) is a condition in which the ventricles contract more than 100 times per minute.

Synchronized cardioversion is the recommended treatment for patients who have a symptomatic, unstable reentry SVT or V-tach with pulses. Synchronized cardioversion is also routinely used to treat unstable atrial flutter and unstable atrial fibrillation. Cardioversion may not be effective when treating junctional tachycardia or ectopic or ...Summary. Ventricular fibrillation, or VFib or VF, is a dangerous arrhythmia that causes the heart's lower chambers (ventricles) to erratically quiver instead of pumping blood as they should. VFib results in sudden cardiac arrest and requires emergent defibrillation (electric shock) to restore the heart's normal rhythm.Since the ventricles are responsible for pumping blood to the lungs and throughout the body, ventricular arrhythmias are often deadly.
