Cardiac dyssynchrony correlates with left ventricular remodeling after myocardial infarction
(SOC MEDICA SANTIAGO, 2009)
Background: Cardiac dyssynchrony is common in advanced heart failure (HF), but the changes in cardiac synchrony after myocardial infarction (MI) have not been adequately described. Aim: To study the relationship between ...
Spatial variance in the 12-lead ECG and mechanical dyssynchrony
(Springer, 2021-05)
Introduction: Electrical transmission disorders have a deleterious effect on cardiac depolarization, resulting in a disorganized ventricular contraction that reduces global mechanical efficiency; this mechanical dyssynchrony ...
Reproducibility of global LV function and dyssynchrony parameters derived from phase analysis of gated myocardial perfusion SPECT: A multicenter comparison with core laboratory setting
(Springer, 2020)
Background Gated myocardial perfusion scintigraphy (GMPS) phase analysis is an important tool to investigate the physiology of left ventricular (LV) dyssynchrony. We aimed to test the performance of GMPS LV function and ...
Cardiac dyssynchrony correlates with left ventricular remodeling after myocardial infarctionLa disincronía cardíaca se correlaciona con el remodelado ventricular izquierdo postinfarto agudo al miocardio
(2009)
Background: Cardiac dyssynchrony is common in advanced heart failure (HF), but the changes in cardiac synchrony after myocardial infarction (MI) have not been adequately described. Aim: To study the relationship between ...
Depolarization spatial variance as a cardiac dyssynchrony descriptor
(Elsevier, 2019-03)
Ventricular depolarization dispersion refers mainly to heterogeneity in interlead QRS durations. Here, we propose the spatial variance (SVd) to describe depolarization dispersion about a mean QRS morphology. We hypothesize ...
Relationship between mechanical and metabolic dyssynchrony with left bundle branch block: Evaluation by 18-fluorodeoxyglucose positron emission tomography in patients with non-ischemic heart failure
(2012)
Background: Ventricular dyssynchrony is a common finding in patients with heart failure (HF), especially in the presence of conduction delays. The loss of ventricular synchrony leads to progressive impairment of contractile ...
Usefulness of ventricular sense response in last-generation cardiac resynchronization therapy devices
(Churchill Livingstone Inc Medical Publishers, 2022-03)
Objectives: High percentages of pacing were associated to maximal symptomatic and mortality benefit from cardiac resynchronization therapy (CRT). Loss of CRT pacing is linked to intrinsic ventricular activation preceding ...
Prevalence and Prognostic Value of Ventricular Dyssynchrony in Chagas' Cardiomyopathy
(2011)
BACKGROUND: Chagas' cardiomyopathy is one important cause of heart failure in Latin America. Ventricular dyssynchrony may be a factor of decompensation in the course of this disease, but there are no data on its prevalence ...
Acute effect of iloprost inhalation on right atrial function and ventricular dyssynchrony in patients with pulmonary artery hypertension
(2016)
BACKGROUND: Right atrium function and ventricular function have significant prognostic value in pulmonary arterial hypertension patients. Acute changes in right ventricular synchrony and right atrium function postiloprost ...
