Abstract: A method for identifying reversible cardiac dyssynchrony (RCD) of a patient and treating the RCD measures an event relating to a rapid increase in the rate of pressure increase within the left ventricle. The method calculates a first time delay between the event and a first reference time. If the first time delay is longer than a set fraction of electrical activation of the heart, then the presence of cardiac dyssynchrony in the patient is identified. Pacing is applied to the heart, and a second time delay between the event following pacing and a second reference time following pacing is calculated. If the second time delay is shorter than the first time delay, the method identifies a shortening of a delay to onset of myocardial synergy, OoS, thereby identifying the presence of RCD in the patient. Treatment of the RCD is performed.

Abstract: A method for automatically determining optimum welding parameters for carrying out a weld on a workpiece carries out test welds on test workpieces along test welding tracks, and at each test weld a welding parameter is changed automatically along the test welding track from a predefined initial value to a predefined final value.

A quality function for characterizing the test weld seam quality in accordance with the changed weld parameters is calculated from the quality parameter. An optimum quality function is ascertained, and the values for the optimum welding parameters are defined based on each quality parameter at this quality function optimum and the corresponding test weld track locations and saved.
