LEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...
متن کاملQRS duration and echocardiographic evidence of left ventricular dyssynchrony in patients with left ventricular systolic dysfunction.
OBJECTIVE To determine the association between left ventricular (LV) dyssynchrony assessed by tissue Doppler imaging (TDI) in patients with left ventricular ejection fraction (LVEF) < 35% and prolonged ventricular depolarization on electrocardiography. STUDY DESIGN A cross-sectional study. PLACE AND DURATION OF STUDY The Aga Khan University, Karachi, from June to September 2007. METHODOLO...
متن کاملEvidence of left ventricular dyssynchrony resulting from right ventricular pacing in patients with severely depressed left ventricular ejection fraction.
AIMS Cardiac resynchronization therapy (CRT) has recently emerged as an effective treatment for patients with moderate-to-severe systolic heart failure and left bundle branch block (LBBB). Right ventricular pacing (RVP) leads to an LBBB-like pattern in the electrocardiogram. The aim of this study was to evaluate the frequency of ventricular mechanical dyssynchrony in patients induced by RVP. ...
متن کاملEchocardiographic Evaluation of left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation
Extended abstract Echocardiographic Evaluation of Left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation Cardiovascular disease (CVD) is an important, leading cause of mortality and morbidity in patients with chronic kidney disease (CKD) as well as in renal transplant recipients. Cardiovascular complications become more important in children because of the i...
متن کاملLeft Ventricular Dilatation Increases the Risk of Ventricular Arrhythmias in Patients With Reduced Systolic Function
BACKGROUND Reduced left ventricular (LV) ejection fraction increases the risk of ventricular arrhythmias; however, LV ejection fraction has a low sensitivity to predict ventricular arrhythmias. LV dilatation and mass may be useful to further risk-stratify for ventricular arrhythmias. METHODS AND RESULTS Patients from the Genetic Risk of Assessment of Defibrillator Events (GRADE) study (N=930)...
