Systems and methods of patient data compression

A system comprising a medical device comprising:

• at least one first sensor configured to acquire first electrocardiogram (ECG) data descriptive of a patient condition;
• at least one second sensor configured to acquire second ECG data descriptive of the patient condition;
• at least one network interface;
• and
• at least one processor coupled to the at least one first sensor, the at least one second sensor, and the at least one network interface and configured to
• calculate difference data between the first ECG data and the second ECG data;
• store the difference data in association with the first ECG data;
• compress the first ECG data and the difference data to generate compressed data;
• and
• transmit the compressed data to a programmable device distinct from the medical device.

A system comprising a medical device comprising:
