Cardioverter Defibrillator Minimizes Inappropriate Shocks

A new line of implantable cardioverter defibrillators (ICDs) addresses the important clinical need of minimizing inappropriate shocks for supraventricular tachycardias (SVTs). The products offer precise, patient-specific SVT discrimination and an advanced atrial-ventricular association algorithm. Each ICD comes in a small, compact size that is easy to implant and is designed to improve patient comfort and esthetics.

Called Photon Micro DR/VR, these ICDs deliver a range of electrical therapies, ranging from mild stimulation to more powerful shocks to treat patients with ventricular tachycardia and ventricular fibrillation, common contributors to sudden cardiac death. The rate-adaptive dual- and single-chamber devices were developed by St. Jude Medical, Inc. (St. Paul, MN, USA), a complementary line to the company's Photon DR ICD.

"Clinicians will appreciate using Photon Micro ICDs in their clinical practice because of their versatility,” said Dr. Luis A. Pires, director of cardiac electrophysiology at St. John Hospital and Medical Center (Detroit, MI, USA). "This versatility encompasses ease of device implantation due to their small size, rhythm discrimination, and considerable therapeutic flexibility for improving patient safety.”
