Systems and methods for interelectrode distance optimization in a retractable multi-use cardiac monitor

A method of collecting electrocardiogram (ECG) data with a retractable multi-use cardiac monitor, wherein the retractable multi-use cardiac monitor includes a processor and a memory, a first side that includes a first housing wherein a first sensing connector is on the outside of the first housing, a second side including a second housing including a wire retractor and a second sensing connector, wherein the second sensing connector is on the outside of the second housing, and a wireless radio, the method comprising:

• extending from the wire retractor a wire that connects the second and first sides to vary a linear distance between the second and first sensing connectors, defined as an interelectrode distance;
• collecting ECG data from the first and second sensing connectors of the retractable multi-use cardiac monitor, wherein the first and second sensing connectors are placed against the skin of a patient;
• recording the collected ECG data onto the memory of the retractable multi-use cardiac monitor;
• calculating, using the processor, an optimum electrode vector length between the first sensing connector and the second sensing connector based at least in part on the ECG data and on the interelectrode distance;
• and
• transmitting the interelectrode distance and a portion of the collected ECG data to a destination.

A method of determining an optimum electrode vector length between a first sensing connector of a first side of a retractable multi-use cardiac monitor and a second sensing connector of a second side of the retractable multi-use cardiac monitor, comprising:

• performing at least one data collection comprising the steps of:
• determining a distance between the first sensing connector of the retractable multi-use cardiac data monitor and the second sensing connector of the retractable multi-use cardiac data monitor, wherein the distance defines an interelectrode distance,
• recording the interelectrode distance,
• collecting electrocardiogram (ECG) data through the first and second sensing connectors, and
• recording the collected ECG data;
• calculating an optimum electrode vector length between the first sensing connector of the first side of the retractable multi-use cardiac monitor and the second sensing connector of the second side of the retractable multi-use cardiac monitor based on the ECG data recorded in the at least one data collection and the interelectrode distance recorded in the at least one data collection;
• generating a notification of that the optimum electrode vector length has been found.
