1. An arrhythmia monitoring system, comprising:
an external heart monitoring device for a patient comprising:
(a) a plurality of electrocardiogram (ECG) electrodes configured to sense surface ECG activity of the patient;
(b) ECG processing circuitry configured to process the surface ECG activity of the patient to provide at least one ECG signal for the patient on at least one ECG channel;
(c) a non-transitory computer-readable medium comprising a rhythm change classifier, the rhythm change classifier comprising at least one neural network trained based on a historical collection of a plurality of ECG signal portions with known rhythm change information; and
(d) at least one processor operatively connected to the at least one ECG channel and the non-transitory computer-readable medium, the at least one processor configured to:
(i) receive the at least one ECG signal received via the at least one ECG channel,
(ii) detect, with the rhythm change classifier, time data corresponding to a predetermined rhythm change in the at least one ECG signal, the time data comprising at least one of a start time, a time interval, or any combination thereof,
(iii) determine, based on the detected time data, at least one ECG signal portion associated with the detected time data corresponding to the predetermined rhythm change in the at least one ECG signal, and
(iv) transmit the at least one determined ECG signal portion to a remote computer system,
wherein the at least one ECG channel comprises a plurality of ECG channels, wherein the at least one ECG signal comprises at least one respective ECG signal associated with each respective ECG channel of the plurality of ECG channels, wherein the plurality of ECG channels comprises a first ECG channel and a second ECG channel, wherein the at least one ECG signal comprises a first respective ECG signal associated with the first ECG channel and a second respective ECG signal associated with the second ECG channel, and wherein the first respective ECG signal is orthogonal to the second respective ECG signal.
