Common Arrhythmias Treated Atrial Fibrillation with Rapid Ventricular Response Atrial Flutter with Inadequate Control Supraventricular Tachycardia (SVT) Unresponsive to Vagal Maneuvers Stable Ventricular Tachycardia Pre-Procedure Assessment and Preparation Prior to delivering a shock, a thorough assessment is mandatory to ensure the procedure is indicated and safe. By delivering a shock during the synchronized phase, clinicians aim to stop the re-entrant circuits or chaotic firing that causes arrhythmias such as atrial fibrillation or unstable supraventricular tachycardia.
Defibrillator Cardioversion Synchronized Shock Process: Step-by-Step Explanation
Upon confirmation of synchronization, the shock is delivered, often resulting in an audible click and the immediate observation of a restored rhythm on the monitor. The goal is to allow the heart's natural pacemaker to regain control and reestablish effective perfusion to vital organs.
Proper electrode placement and energy selection are determined by the device manufacturer and clinical guidelines to optimize efficacy. Signs of instability may include chest pain, hypotension, altered mental status, or signs of shock, necessitating immediate action to prevent cardiac arrest or organ damage.
Synchronized Shock Process for Defibrillator Cardioversion
One pad is placed below the clavicle, and the other on the left side of the chest, ensuring they do not overlie one another. Indications include rapid atrial fibrillation with severe symptoms, unstable supraventricular tachycardia, or ventricular tachycardia with a pulse.
