Benefits of technology

The patent describes a cardiac rhythm management system that can treat abnormal heart rhythms. The system includes a lead that can be placed in the heart to monitor and treat the abnormal rhythms. The lead can be placed in either the atrial or ventricular region of the heart, or both. The system can also use an implantable cardiac device to deliver therapy to the heart. The technical effect of this system is that it provides a more convenient and safe way to treat abnormal heart rhythms, without the need for placement in the coronary sinus / great vein region.

Problems solved by technology

However, placing the electrode in the coronary / sinus great vein portion of the heart is an extremely difficult procedure for the implanting physician.

Abstract

A cardiac rhythm management system, such as an implantable cardioverter-defibrillator (ICD), provides atrial anti-tachyarrhythmia therapy, such as a bipolar or unipolar electrical cardioversion countershock, or provides both atrial and ventricular anti-tachyarrhythmia therapy. The atrial and ventricular anti-tachyarrhythmia therapies have independent cardioversion-defibrillation energy levels and other parameters. The system provides an endocardial lead that is convenient to implant for providing the anti-tachyarrhythmia therapy. The endocardial lead includes a first supraventricular electrode disposed in the atrium and superior vena cava, and optionally includes a first ventricular electrode and ICD housing electrode.
