Three-dimensional echocardiography by semi-automatic border detection in assessment of left ventricular volume and ejection fraction: comparison with magnetic resonance imaging.

abstract：:Sustained left ventricular systolic dysfunction after transient myocardial ischemia is well known as "myocardial stunning", but little is known about the recovery in left ventricular diastolic function. Changes in left ventricular systolic and diastolic performance following dobutamine-induced ischemia were investigat...
