Predicting ventricular arrhythmias in cardiac resynchronization therapy: The impact of persistent electrical dyssynchrony
(Wiley, 2016)
BackgroundAlthough response to cardiac resynchronization therapy (CRT) has been conventionally assessed with left ventricular volume reduction, ventricular arrhythmias (ventricular tachycardia/ventricular fibrillation ...
Changes in electrocardiographic p wave parameters after cryoballoon ablation and their association with atrial fibrillation recurrence
(Wiley-Blackwell, 2016)
Background: Changes in P wave parameters after circumferential pulmonary vein isolation (CPVI) have been previously identified. In this study, we aimed to determine the changes in P wave parameters surface electrocardiogram ...
Effect of QRS narrowing after cardiac resynchronization therapy on functional mitral regurgitation in patients with systolic heart failure
(Elsevier Inc., 2016)
The determinants of improvement in functional mitral regurgitation (FMR) after cardiac resynchronization therapy (CRT) remain unclear. We evaluated the predictors of FMR improvement and hypothesized that CRT-induced change ...
QRS prolongation after cardiac resynchronization therapy is a predictor of persistent mechanical dyssynchrony
(Springer, 2016)
Purpose Prolonged QRS duration is the main selection criterion for cardiac resynchronization therapy (CRT) which ameliorates left ventricular mechanical dyssynchrony (MD). However, consequences of post-CRT QRS prolongation ...
Adjusting the QRS duration by body mass index for prediction of response to cardiac resynchronization therapy: Does one QRS size fit all?
(Wiley, 2016)
Background: QRS duration (QRSd) is known to be affected by body weight and length. We tested the hypothesis that adjusting the QRSd by body mass index (BMI) may provide individualization for patient selection and improve ...
Native electrocardiographic qrs duration after cardiac resynchronization therapy: The impact on clinical outcomes and prognosis
(Churchill Livingstone Inc Medical Publishers, 2016)
Background: We investigated whether reversed electrical remodeling (RER), defined as narrowing of the native electrocardiographic QRS duration after cardiac resynchronization therapy (CRT), might predict prognosis and ...
