A wearable cardioverter defibrillator system for an ambulatory patient (82, 282, 1582, 1782) who is overseen by an attendant other than the patient, the WCD system comprising: a housing (1901, 2102, 2201); an energy storage module (1950, 2150, 2250) within the housing, the energy storage module configured to store an electrical charge; a support structure (170, 270, 370, 470, 570, 670, 770, 1571, 1770) configured to be worn by the patient; a first defibrillation electrode (104, 105, 304, 404, 444, 424, 504, 505, 604, 605, 704, 705, 1404, 1415, 1505, 2004, 2005) configured to be coupled to the housing, the first defibrillation electrode having a first pad (104, 304, 401, 421, 441, 504, 604, 704, 1404, 2004) configured to be coupled to the support structure so that the first pad is maintained on a body of the patient when the support structure is worn by the patient; a sensor (1920, 2120, 2220) configured to sense a parameter of the patient and to render a patient input responsive to the sensed parameter; a second defibrillation electrode (108, 308, 408, 508) distinct from the first defibrillation electrode, the second defibrillation electrode (108, 308, 408, 508) configured to be coupled to the housing, the second defibrillation electrode having a second pad that includes adhesive material (423, 1423) and is configured to be maintained on the body of the patient via the adhesive material; a user interface (188, 680, 780, 1980, 2180, 2280) that includes a shock input device configured to receive a shock input entered by the attendant; and a processor (1930, 2130, 2230) configured to: determine, from the patient input, whether or not a first shock criterion is met, cause, responsive to the first shock criterion being met, at least some of the stored electrical charge to be discharged through the patient via the first defibrillation electrode but not via the second defibrillation electrode, so as to deliver a first shock to the patient when the support structure is worn by the patient, and cause, responsive to the shock input being received by the shock input device, at least some of the stored electrical charge to be discharged through the patient via the second defibrillation electrode but not via the first defibrillation electrode, so as to deliver a second shock to the patient, the second shock distinct from the first shock. a housing (1901, 2102, 2201);
