Ecg belt systems to interoperate with imds

A method for use in cardiac evaluation, comprising:

• monitoring electrical activity from tissue of a patient using a plurality of external electrodes to generate a plurality of electrical signals over time;
• and
• using a portable computing apparatus operably coupled to the plurality of electrodes, performing at least one of:
• optimizing at least one pacing parameter of the implantable pacing device based on the plurality of electrical signals;
• and
• determining cardiac synchrony based on the plurality of electrical signals.

A system for use in cardiac evaluation comprising:

• an electrode apparatus comprising a portable amplifier and a plurality of external electrodes to be disposed proximate to a patient's skin;
• a portable computing apparatus comprising processing circuitry, the computing apparatus operably coupled to the electrode apparatus and configured to be operably coupled to an implantable pacing device of the patient, the portable computing apparatus configured to:
• monitor electrical activity from tissue of a patient using the plurality of external electrodes to generate a plurality of electrical signals over time;
• measure one or more parameters of the patient based on the plurality of electrical signals;
• determine one or more metrics of the patient based on the one or more parameters;
• and
• transmit the one or more metrics to a smart device.
