Patients who have heart failure and have electrical evidence of delay in the contraction of the left ventricle on an ECG tracing of the heart are eligible for biventricular pacing. Recent ...
Despite the dramatic effect of cardiac resynchronization therapy (CRT) on survival and morbidity in people with congestive heart failure, 50-70% of eligible patients do not respond to this...
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are ch...
The purpose of this study is to determine how electrical impedance is modified in relation to extracellular space body fluid retention detected by an electrical bioimpedance method in pat...
For patients with advanced heart failure, Cardiac Resynchronization Therapy (CRT) has been a major improvement. The treatment improves symptoms and prolongs life in selected patients with ...
Obtain initial estimates of the change in brachial artery endothelial function and maximal oxygen uptake (VO ) with 8 weeks of low-frequency electrical muscle stimulation (LF-EMS) or sham in patients...
T-wave alternans (TWA), a marker of electrical instability, can be modulated by cardiac resynchronization therapy (CRT). The relationship between TWA and heart failure response to CRT has not been cle...
We evaluated the influences of selected factors on electrical lead failure (ELF) occurrence in patients referred for transvenous lead extraction (TLE) procedures.
The aims of this paper were to evaluate the levels of Vitamin D (VitD) in patients with heart failure (HF), compared to a control group, to assess the effects of VitD on HF outcome and to compare VitD...
Heart failure or congestive heart failure remains a major public health concern on the global scale. End-stage heart failure is a severe disease where the heart is unable to pump enough oxygen and nut...
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Methods to induce and measure electrical activities at specific sites in the heart to diagnose and treat problems with the heart's electrical system.
Procedure which includes placement of catheter, recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, etc. Specific angiographic injection techniques are also involved.
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
