Cardiac monitoring system with automatic delection of electrode positioning and connection box switching

A cardiac monitoring system, comprising:

• a first plurality of input ports, each input port in the first plurality of input ports configured to receive signals from a corresponding electrode patch, in a plurality of electrode patches, placed at a corresponding predetermined position in a plurality of positions on a body of a subject;
• a first processor configured to:
• process the signals received at the first plurality of input ports;
• and
• determine an electrocardiogram of the subject's heart when each input port in the first plurality of input ports receives one or more signals from the corresponding electrode patch;
• a connection box comprising:
• a second plurality of input ports, each input port in the second plurality of input ports connected to an electrode patch in the plurality of electrode patches by one or more wires;
• a plurality of output ports, each output port in the plurality of output ports connected to an input port in the first plurality of input ports by one or more wires;
• a second processor;
• a switch;
• and
• a non-transitory computer-readable medium storing a plurality of predetermined signal profiles, each predetermined signal profile associated with an electrode patch in the plurality of electrode patches, each predetermined signal profile generated from signals received by the associated electrode patch placed at the corresponding predetermined position on bodies of a plurality of persons;
• wherein the second processor is configured to:
• receive, after a start of monitoring cardiac activity of the subject, signals from each electrode patch in the plurality of electrode patches, each electrode patch signal comprising a signal received by the electrode patch from the subject's heart;
• compare a profile of the signals received from each electrode patch with the predetermined signal profile associated with the electrode patch;
• determine that the profile of the signals received from a set of one or more electrode patches in the plurality of electrode patches does not match the predetermined signal profile corresponding to the electrode patch;
• for each electrode patch in the set of electrode patches:
• determine an actual position of the electrode patch on the body of the subject by matching the profile of the electrode patch's signal with another predetermined signal profile in the plurality of predetermined signal profiles;
• and
• route the electrode patch signal, through the switch and an output port of the connection box, to an input port in the first plurality of input ports that corresponds to the electrode patch.
