EM1809E "The Egg Came First: Arrhythmia Induced Cardiomyopathy" (IM GR-091418)

  1. Arrhythmia induced cardiomyopathy (AIC) is a form of heart failure induced by atrial or ventricular arrhythmias.
    1. Tachycardia mediated-cardiomyopathy (rapid heart rhythms) 
    2. Premature ventricular contractions (PVC)-induced cardiomyopathy 
  2. A common clinical problem is determining whether AIC is the primary cause of cardiomyopathy or if it is secondary to cardiomyopathy of a different etiology 
  3. A hallmark of AIC is partial or complete reversibility of ventricular dysfunction once the arrhythmia is eliminated or controlled 
  4. Early recognition and prompt treatment of AIC may normalize heart function, prevent further development of heart failure, and prevent sudden cardiac death.

Cardiologist Richard Wu, M.D. is a nationally recognized expert in evaluating and treating heart rhythm disorders and has been at the forefront of performing cardiac ablation procedures to treat these conditions for over 20 years. Dr. Wu earned both his undergraduate and medical degrees with honors at Duke University. As a Sarnoff Cardiovascular Research Foundation Fellow and Scholar, he was encouraged to pursue an academic career in the field of cardiology. He completed his training in internal medicine, cardiology and cardiac electrophysiology at the Johns Hopkins Hospital. He was inspired by his mentors to specialize in the new developing field of catheter ablation, a minimally invasive method for eliminating fast heart rhythms. His first faculty position was the University of Oklahoma, where he worked with pioneers in the development of 3D mapping and ablation of complex arrhythmias. Dr. Wu joined the faculty at the University of Texas Southwestern Medical Center at Dallas in 2006, where he now serves as Professor of Internal Medicine and is the Director of the Electrophysiology Lab at Clements University Hospital. Dr. Wu has a particular interest in catheter ablation of atrial fibrillation, ventricular tachycardia, and arrhythmias in patients with accessory atrioventricular pathways (Wolff-Parkinson-White syndrome). In addition to helping patients, Dr. Wu enjoys his role mentoring young physicians in training and teaching them innovations in his specialty.
