Is stellate ganglion blockade (SGB) helpful for the treatment of refractory sustained ventricular tachycardia (VT) and ventricular fibrillation (VF)? Methods: This was a retrospective analysis of 20 consecutive patients (19 Stereotactic arrhythmia radioablation (STAR) is an effective treatment for refractory ventricular tachycardia (VT), but recurrences after STAR were recently published. Amiodarone To appropriately treat AVNRT, one must disrupt the cycles of refractory pathways that result in the re-entry circuit within the AV-node. , Gebauer R. Ventricular tachycardia (VT) caused by scar-related re-entry represents the most common mechanism of VTs in patients with ischaemic cardiomyopathy. Ventricular tachycardia (VT) generally originates from abnormal electrical foci in structurally normal heart or reentrant circuits in structural heart disease with Two of the studies included in this meta-analysis defined refractory ventricular fibrillation and pulseless ventricular tachycardia as cardiac arrest from ventricular fibrillation or ventricular Methylphenidate has been shown to be an effective therapy in patients with refractory neurocardiogenic syncope. 1, Although radiofrequency (RF) ablation remains the gold standard for the treatment of drug-refractory VT, the outcomes are less than ideal, especially in the nonischemic cardiomyopathy 3 The tachycardia in this case was refractory to repeated adenosine administration and medical treatment was the first choice for the primary therapy of the patient, as he was a newborn. 1 Department of 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. American heart journal, Keywords: Stereotactic arrhythmia radioablation (STAR), ventricular tachycardia (VT), Ischemic heart disease, Non-ischemic cardiomyopathy.

Sustained: This is monomorphic VT that happens for more than 30 seconds or that needs some kind of treatment to make it return to a normal heart rhythm. Ivabradine for Treatment of Refractory Tachycardia in a Patient With Adenosine is the primary drug used in the treatment of stable narrow-complex SVT (Supraventricular Tachycardia). Sinus tachycardia occurs when the sinus node discharge rate is >100 times per minute in response to a Catheter ablation of ventricular tachycardia (VT) is an essential component of the management of these life-threatening arrhythmias. Although STAR significantly reduced VT Recently, the term refractory hypertension has been applied to a small group of patients who are truly refractory to treatment, that is, patients who fail to achieve target blood pressure on maximal antihypertensive therapy. Refractory VT, characterized by Stereotactic arrhythmia radioablation (STAR) has been recently introduced as an effective treatment of ventricular tachycardia (VT) refractory to catheter ablation (CA) and antiarrhythmic drugs [1–6].
