The patient has stable VT. The term stable refers only to the notion that the patient has a palpable pulse and a BP that allows for
peripheral organ perfusion. The rhythm has lasted for more than 30 seconds, which classifies it as sustained VT, an inherently unstable rhythm that can degenerate into VF. Hence, continued monitoring would not be appropriate. Defibrillation would be appropriate for unstable VT or VF, but is not yet necessary in this setting. Adenosine is only effective for certain idiopathic VTs and is usually ineffective for those associated with structural heart disease, as in this case. The appropriate management is either synchronized electrical cardioversion, which is not optimal in a conscious patient, or initiation of IV antiarrhythmic therapy (eg, procainamide, amiodarone, lidocaine).4
- Administer IV amiodarone and initiate an amiodarone drip.
