1. A wearable medical device for providing treatment to a patient responsive to monitoring the patient, the wearable medical device comprising:
a plurality of electrocardiogram (ECG) sensors configured to be in electrical communication with a body of the patient;
a plurality of therapy electrodes configured to provide electrical therapy to a heart of the patient; and
a control unit in communication with the plurality of ECG sensors and the plurality of therapy electrodes, the control unit comprising
a housing,
two or more touch controls configured to be concurrently contactable with respective fingers of the patient, the two or more touch controls including
a first touch control comprising a force sensor, and
a second touch control comprising a force-activated switch;
monitoring circuitry in communication with the plurality of ECG sensors and the two or more touch controls;
a non-transitory computer-readable memory in communication with the monitoring circuitry; and
at least one processor in communication with the non-transitory computer-readable memory and the monitoring circuitry, the at least one processor configured to
detect, via the plurality of ECG sensors, an indication of a cardiac anomaly in the patient,
provide a patient notification regarding commencement of the treatment in response to detecting the indication of the cardiac anomaly,
after providing the patient notification, monitor, over a predetermined period of time, signals from the first touch control and the second touch control, wherein monitoring comprises
analyzing a first signal from the force sensor of the first touch control to identify a force value below a first threshold level of force and at or above a second threshold level of force, and
analyzing a second signal from the second touch control to identify actuation of the force-activated switch, and
responsive to detecting actuation of the force-activated switch of the second touch control and application of the force value at the first touch control, delay the treatment.
