Objectives: We sought to test whether the mechanical dyssynchrony assessed by tissue
Doppler imaging (TDI) is a predictor of cardiac events in patients with congestive heart …

Objectives: To compare the incidence of diastolic and systolic asynchrony, assessed by
tissue Doppler imaging (TDI), in patients with congestive heart failure (CHF) and severe left …

The present study evaluated the prevalence of mechanical inter-and intraventricular
dyssynchrony in patients with heart failure and preserved left ventricular (LV) ejection …

Background Recent clinical trials have challenged the clinical applicability of mechanical
dyssynchrony in predicting cardiac resynchronisation therapy response. Objective To …

Objective: To study the possible occurrence of left ventricular (LV) systolic and diastolic
asynchrony in patients with systolic heart failure (HF) and narrow QRS complexes. Design …

Objectives: To test the hypothesis that echocardiographic dyssynchrony may assist in the
selection of patients with borderline QRS duration for cardiac resynchronization therapy …

Introduction: Patients with end‐stage heart failure and a wide QRS complex are considered
candidates for cardiac resynchronization therapy (CRT). However, 20% to 30% of patients …

BACKGROUND: Electrical dyssynchrony is one of the main criteria for determining eligibility
for cardiac resynchronization therapy (CRT). However, recent data support the use of …

Objectives: The present study aimed to examine whether diastolic and systolic asynchrony
exist in diastolic heart failure (DHF) and their prevalence and relationship to systolic heart …

Objectives: This study sought to compare tissue Doppler imaging (TDI) with velocity-
encoded (VE) magnetic resonance imaging (MRI) for left ventricular (LV) dyssynchrony …
