It increases the electrical activity of the heart through its beta activities. Warnings Inadvertently induced high arterial blood pressure may result in angina pectoris, aortic rupture or cerebral hemorrhage. In other words, lidocaine decreases automaticity and suppresses ventricular arrhythmias. Google Scholar 3. While lidocaine is a well-known and established ACLS . Defibrillation is the treatment of choice and should occur as soon as possible. Next, isoproterenol is contraindicated in clients with tachyarrhythmias or angina pectoris, as well as in those experiencing cardiac glycoside toxicity. If ventricular fibrillation was secondary to degeneration of another arrhythmia that may recur, medication and other therapies (eg, radiofrequency catheter ablation [RFCA], pacemaker placement, automatic ICD [AICD], surgery) may be aimed at prevention of that arrhythmia. • Proceed with Automated Defibrillator Procedure If epinephrine is used prior to ocular surgery, especially for injection with a local anesthetic, systemic sympathomimetic effects may occur; surgery should not be started until restlessness has subsided. Due to lidocaine's antiarrhythmic properties, the primary use of lidocaine is for cardiac arrest from ventricular fibrillation (VFib) and pulseless ventricular tachycardia.
