• decreased cardiomyocytes intracellular calcium transients in the absence of and following isoproterenol stimulation
|
• increased intraventricular septum in the absence of and following isoproterenol stimulation
|
• left ventricular posterior wall at systole is increased in the absence of and following isoproterenol stimulation
• left ventricular internal dimensions at diastole is decreased
• however, left ventricular internal dimensions at diastole are normal

• in the absence of and following isoproterenol stimulation
|
• increased ejection fraction, left ventricular shortening and fractional shortening in the absence of and following isoproterenol stimulation
|
• increased sarcomere fractional shortening in cardiomyocytes in the absence of and following isoproterenol stimulation
