متن کاملCardiac Resynchronization Therapy; Biventricular Pacing
Although the estimates from limited studies vary on the proportion of patients with heart failure who also have ventricular dyssynchrony as reflected by a prolonged QRS complex, often in the form of left bundle branch block, the number of such patients is large (27% to 53%) and it is certainly in excess of the rate for the general population. Among these patients, 10% to 15% are candidates for ...
متن کامل[Cardiac pacing and cardiac resynchronization therapy].
In this issue of iJACC (JACC: Cardiovascular Imaging), Botvinick et al. (1) perform a complex study involving the performance of equilibrium radionuclide myocardiography with phase analysis during ventricular tachycardia. The authors identify specific characteristics that define tolerability of the arrhythmia in individual patients. Most of these discriminating factors in the 2 patient groups i...
متن کاملA review of multisite pacing to achieve cardiac resynchronization therapy.
Non-response to cardiac resynchronization therapy remains a significant problem in up to 30% of patients. Multisite stimulation has emerged as a way of potentially overcoming non-response. This may be achieved by the use of multiple leads placed within the coronary sinus and its tributaries (dual-vein pacing) or more recently by the use of multipolar (quadripolar) left ventricular pacing leads ...
متن کاملEvaluation of Left Ventricular Endocardial Cardiac Resynchronization Therapy in a Non-responder with Ventricular Arrhythmias
Approximately one third of patients treated with cardiac resynchronization therapy do not derive any detectable benefit. In these patients, acute invasive hemodynamic evaluation can be used for therapy optimization. This report describes the use of systematic invasive hemodynamic measurements for clinical decision making in a patient who experienced severe ventricular arrhythmias and clinical d...
