1. A system comprising:
a medical device comprising an acceleration sensor configured to generate acceleration data and at least two electrodes configured to generate electrocardiogram (ECG) data;
a processor; and
a memory containing computer-executable instructions that, when executed by the processor, cause the processor to:
obtain the acceleration data and the ECG data from a first range of time and a second range of time different from the first range,
generate respiration data based on the acceleration data, and
determine that the medical device has flipped in orientation during the second range of time by comparing the respiration data and the ECG data of the first range of time with the respiration data and the ECG data of the second range of time.
