Deleterious effect of right ventricular apical pacing on left ventricular diastolic function and the impact of pre-existing diastolic disease.
AIMS Right ventricular apex (RVA) pacing may have deleterious effects on left ventricular (LV) systolic function, but its impact on LV diastolic function has not been explored. METHODS AND RESULTS Ninety-seven patients with sinus node dysfunction and ejection fraction (EF) ≥ 50% with permanent RVA pacing were randomly programmed to V-sense and V-pace modes and examined by echocardiography. Ti...
متن کاملLEFT 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 کاملThe influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography
Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...
متن کاملLeft ventricular strain analysis reveals better synchrony and diastolic function for septal versus apical right ventricular permanent pacing.
OBJECTIVES Left ventricular function and synchrony may be altered by right ventricular (RV) apical pacing. Septal pacing might be a better alternative. We compared effects on cardiac synchrony and function, between the 2 pacing sites, in chronically implanted patients. MATERIAL AND METHODS 40 pacing-dependent patients (74±9 years, 21 men), 20 paced at the apex, were studied 11±4 months after ...
متن کاملVentricular remodeling in right ventricular apical pacing.
OBJECTIVE To determine ventricular remodeling (VR) and the role of clinical and functional variables in patients with normal cardiac function who underwent right ventricular apical pacing (RVAP). METHODS Among the 268 consecutive patients with standard pacemaker due to complete atrioventricular block (CAVB), those with left ventricular ejection fraction (LVEF) < 55% and left ventricular end-d...
