Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
CRT devices have been shown to reduce mortality and improve quality of life in patients with heart failure symptoms; a LV ejection fraction less than or equal to 35% and QRS duration on EKG of 120 ms or greater. [18] [19] Biventricular pacing alone is referred to as CRT-P (for pacing).
CRT: People with NYHA class III or IV, left ventricular ejection fraction (LVEF) of 35% or less and a QRS interval of 120 ms or more may benefit from cardiac resynchronization therapy (CRT; pacing both the left and right ventricles), through implantation of a bi-ventricular pacemaker. This treatment modality may alleviate symptoms, improving ...
"The MultiPoint Pacing trial is a study of patients who may not receive benefit or are unresponsive to standard CRT single-point pacing. We are evaluating whether MPP can increase the potential ...
This CRT-P system offers more pacing options to deliver higher success rates, as evidenced by robust clinical data. Allure Quadra CRT-P brings the quadripolar lead technology to the pacemaker ...
As with conventional pacemaker therapy, the cardiac contractility modulation device cannot be implanted if the leads cannot be positioned appropriately in the heart. In cases where there is an artificial heart valve between the right atrium and ventricle (a mechanical prosthetic tricuspid valve), the valve function could be greatly affected by ...
Illustration of Implantable Cardioverter Defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
As cases of the HMPV virus continue to increase in the U.S. and in China, here's what you need to know about the virus.
