  3. Evaluation: Brugada criteria for Wide Complex Tachycardia
    1. Only treat as SVT with aberrancy if ALL 4 criteria are absent
      1. Rule has a Test Sensitivity and Test Specificity >96% for VT
    2. Criteria (presence of any one of which suggests Ventricular Tachycardia)
      1. RS complex absent from all precordial leads
      2. R to S interval >100 ms in one precordial lead

  4. Management: Acute Wide Complex Tachycardia
    1. New emphasis on use of choosing only one Antiarrhythmic
      1. Contrast to prior Antiarrhythmic soups
      2. Pro-arrhythmic effects increase with poly-drugs

      1. Long term best option (much better than meds)
      2. Efficacy: 40-50% reduction in sudden death

Tachycardia, Ventricular (C0042514)

Definition (NCI) A disorder characterized by an electrocardiographic finding of three or more consecutive complexes of ventricular origin with a rate greater than a certain threshold (100 or 120 beats per minute are commonly used). The QRS complexes are wide and have an abnormal morphology. (CDISC)
Definition (NCI_CTCAE) A disorder characterized by a dysrhythmia with a heart rate greater than 100 beats per minute that originates distal to the bundle of His.
Definition (NCI_FDA) An abnormally rapid ventricular rhythm with aberrant ventricular excitation, usually in excess of 150 beats per minute.
Definition (MSH) An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
