Claim 0:
1. A non-invasive bodily-attached ambulatory medical monitoring and treatment device for detecting patient movement in order to minimize patient discomfort from pacing pulses delivered from outside the patient's body, comprising:
at least one therapy electrode positioned outside a patient's body;
at least one electrocardiogram (ECG) sensing electrode configured to monitor cardiac activity of the patient, the at least one ECG sensing electrode being positioned outside the patient's body;
a memory storing information indicative of the cardiac activity of the patient;
a therapy delivery interface and associated circuitry configured to implement a pacing routine;
a motion sensor configured to detect movement of the patient; and
at least one processor coupled to the memory, the at least one ECG sensing electrode, the therapy delivery interface, and the at least one therapy electrode and configured to:
identify, within the stored information indicative of the cardiac activity of the patient, a paceable cardiac arrhythmia;
respond to the identified paceable cardiac arrhythmia by initiating the pacing routine;
cause the therapy delivery interface to externally apply a plurality of pacing pulses to the patient in accordance with the pacing routine;
monitor movement of the patient with the motion sensor during external application of the plurality of pacing pulses in accordance with the pacing routine;
identify a predetermined change in the movement of the patient during application of the plurality of pacing pulses; and
at least one of withhold application of the plurality of pacing pulses responsive to identifying the predetermined change in the movement of the patient, or adjust one or more characteristics of the plurality of pacing pulses of the pacing routine responsive to identifying the predetermined change in the movement of the patient.
