Walkup attorneys obtained a binding Kaiser arbitration award in the amount of $946,616 on behalf of the surviving heirs of a Kaiser member who suffered a heart attack at age 48. His survivors contended that Kaiser Walnut Creek physicians should have followed up with Holter monitor test results that the decedent underwent immediately and that a proper workup, including a thallium treadmill examination, would have resulted in a diagnosis of severe coronary artery disease and permitted timely bypass surgery. Kaiser disputed liability, claiming that the findings reflected on the Holter monitor tracings were not diagnostic and were, in fact, insignificant. Kaiser also claimed that bypass surgery would not have prevented the fatal heart attack. The case was arbitrated for five days before a panel of three arbitrators.
