Prolonged Autonomic Dysfunction After Ventricular Ablation, Cardiac Tamponade, and Emergency Open-Heart Surgery: A First-Person Case Report with Integrated Cardiology and Autonomic Analysis
Author(s): Bruce H Knox*
Background: Cardiac tamponade is a recognized but uncommon complication of catheter ablation for ventricular arrhythmias. Although its immediate hemodynamic consequences are well described, prolonged autonomic sequelae after tamponade and emergency cardiac surgery remain poorly represented in the cardiology literature. Case Summary: This report presents a first-person longitudinal case of severe multisystem autonomic dysfunction after ablation of premature ventricular ectopy arising from the left ventricular outflow tract, complicated by cardiac perforation, tamponade, and emergency open-heart repair. Post-operatively, the dominant syndrome was not persistent structural cardiac failure, but a prolonged disturbance of autonomic control characterized by marked cardiovascular lability, orthostatic intolerance, profound fatigue, and gastrointest..
