In embodiments, a WCD system includes one or more transducers that may sense patient parameters from different parts of the patient's body, and thus render physiological inputs from those parameters. First aspects and second aspects may be detected from the physiological inputs. An aggregated first aspect may be generated from the detected first aspects, and an aggregated second aspect may be generated from the detected second aspects. An aggregate analysis score may be determined from the aggregated first aspect and the aggregated second aspect. A shock/no shock determination may be made depending on whether or not the aggregate analysis score meets an aggregate shock criterion. Accordingly, such a WCD system can make shock/no shock determinations by aggregating aspects of multiple patient parameters. Accordingly, multiple inputs are considered in making the shock/no shock determination.
