Vectorcardiography for Optimization of Stimulation Intervals in Cardiac Resynchronization Therapy
Current optimization of atrioventricular (AV) and interventricular (VV) intervals in cardiac resynchronization therapy (CRT) is time consuming and subject to noise. We aimed to prove the principle that the best hemodynamic effect of CRT is achieved by cancelation of opposing electrical forces, detectable from the QRS morphology in the 3D vectorcardiogram (VCG). Different degrees of left (LV) an...
متن کاملMeasurement precision in the optimization of cardiac resynchronization therapy.
BACKGROUND Cardiac resynchronization therapy improves morbidity and mortality in appropriately selected patients. Whether atrioventricular (AV) and interventricular (VV) pacing interval optimization confers further clinical improvement remains unclear. A variety of techniques are used to estimate optimum AV/VV intervals; however, the precision of their estimates and the ramifications of an impr...

In patients with heart failure, left ventricular systolic dysfunction and prolonged QRS complex, cardiac resynchronization therapy (CRT) is a treatment method aimed at restoration of myocardial depolarization synchronicity. However, the extent of clinical and echocardiographic improvement depends on anatomical relations in individual patients, on structural changes in the heart, on intrinsic el...

Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...
متن کاملCardiac Resynchronization Therapy
According to the 2013 update on heart disease statistics from American Heart Association, an estimated 5.1 million Americans ≥20 years of age have a diagnosis of heart failure. In the year 2009, heart failure was noted to be the primary cause of death in >56 000 people and contributed to death of >274 000 people. It is one of the most common causes of hospitalization in patients ≥65 years of ag...
