|
• exhibit mild hypertrophy
|
|
• isolated cardiac myocytes exhibit a significant decrease in fractional cell shortening and smaller dL/dT values
|
|
• the first derivatives of minimum and maximum left ventricular pressure, the fractional shortening, velocity of circumferential shortening corrected, and peak early-filling transmitral diastolic wave velocity are all decreased
• treatment with isoproternol, a beta-adrenergic activator, reversed cardiac impairment in mutant hearts
|
|
• isolated cardiac myocytes exhibit lower relaxation rates (-dL/dt) than wild-type
|
