متن کاملAbnormal Left Ventricular Contraction
Twenty-five patients with pure mitral stenosis and nine normal subjects were studied by selective left ventricular cineangiocardiography. Left ventricular volumes were measured at end systole, throughout diastole, and at end diastole. Although filling curves showed that the left ventricles filled slowly in patients with mitral stenosis, normal end-diastolic volumes were attained provided diasto...
متن کاملIdiopathic Ventricular Tachycardia of Left Ventricular Origin
Background. The signal-averaged ECG has been used to detect late potentials, and it is considered a noninvasive marker for areas of slow conduction requisite for reentrant arrhythmia. Late potentials are not usually found in patients with idiopathic ventricular tachycardia (VT); nevertheless, fragmented electrograms are often recorded in those patients during endocardial mapping. The purpose of...
متن کاملIdiopathic ventricular premature contractions originating from the postero-lateral tricuspid annulus leading to left ventricular disfunction.
A 19-year-old patient with premature ventricular complexes (PVCs) more than 30% on 24 hours was addressed for catheter ablation. Echocardiography showed left ventricular (LV) dilation and systolic dysfunction with 37% of ejection fraction. The patient underwent investigations including cardiac magnetic resonance (MRI) with no other cause of cardiomyopathy being found. Successful ablation of the...
متن کاملAugmentation of Left Ventricular Contraction
In order to assess potential improvement in abnormal left ventricular (LV) wall motion, eighteen subjects sixteen with obstructive coronary artery disease and LV asynergy and two with no evidence of organic heart disease were studied by cardiac catheterization and cineangiography. Ventriculograms were performed at rest and during a constant infusion of l-epinephrine (EPI) at 1-4 ,gg/min after a...
