Ventricular Arrhythmias and Reduced Echocardiographic Inferior Wall Strain: Is Regional Function an Important Risk Marker?
Cardiac resynchronization therapy (CRT) has made a major impact on clinical outcomes in many patients with heart failure with widened QRS complexes and reduced ejection fraction (EF), even in those who are mildly symptomatic. Assessing risk for ventricular tachycardia (VT) or ventricular fibrillation (VF) in patients treated with CRT continues to be of great interest. Despite its known limitati...
متن کاملDispersion of ventricular repolarisation: a marker of ventricular arrhythmias in patients with previous myocardial infarction.
OBJECTIVE To examine whether, in coronary patients after myocardial infarction, the dispersion of ventricular repolarisation measured through QT and JT intervals from a surface electrocardiogram could allow separation of those with ventricular tachyarrhythmias (VT) complicating their myocardial infarct from those without. DESIGN A retrospective comparative study. SETTING University hospital...
متن کاملIs Dynamic Left Ventricular Dyssynchrony a Novel Surrogate Marker in the Patient with Hypertension?
Recently, dynamic left ventricular dyssynchrony (LVD) using exercise echocardiography (ExE) become a promising method in many cardiovascular disease, because it can unveil the pathophysiology, can predict the prognosis and also would be a possible surrogate marker in the treatment monitoring. Especially in the field of cardiac resynchronization therapy, it would be a useful tool for patient sel...
متن کاملVentricular Arrhythmias.
Ventricular tachycardia (VT) is the most common form of wide complex tachycardia and is associated with a high mortality rate. Electrocardiographic analysis remains paramount in diagnosis and helps to direct therapy. Antiarrhythmic agents, although effective in reducing arrhythmia burden, have never demonstrated a mortality benefit. The implantable cardioverter-defibrillator aids not only in th...
متن کاملTherapies for ventricular cardiac arrhythmias.
During recent years, engineers and physicists have become increasingly interested in studying the electrical activity of the heart. Despite the fact that the heart is a complex and highly nonlinear system, its electrical behavior can be studied using a variety of experimental and clinical techniques, and can be modeled mathematically using relatively simple systems of differential equations, al...
