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 کاملClassification of Premature Ventricular Contraction in ECG
Cardiac arrhythmia is one of the most important indicators of heart disease. Premature ventricular contractions (PVCs) are a common form of cardiac arrhythmia caused by ectopic heartbeats. The detection of PVCs by means of ECG (electrocardiogram) signals is important for the prediction of possible heart failure. This study focuses on the classification of PVC heartbeats from ECG signals and, in...
متن کاملAbnormal Left Ventricular Mechanics of Ventricular Ectopic Beats: Insights Into Origin and Coupling Interval in Premature Ventricular Contraction-Induced Cardiomyopathy.
BACKGROUND Left ventricular (LV) dyssynchrony caused by premature ventricular contractions (PVCs) has been proposed as a mechanism of PVC-induced cardiomyopathy. We sought to understand the impact of different PVC locations and coupling intervals (prematurity) on LV regional mechanics and global function of the PVC beat itself. METHODS AND RESULTS Using our premature pacing algorithm, pentage...
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...
