1. A method of mitigating false positive alerts for ischemic ECG patterns in an electrocardiogram (ECG) indicative of ischemia or myocardial infarction, comprising:

  • receiving real-time ECG data;

    measuring a level of noise associated with each of a plurality of ECG segments;

    identifying a lowest-noise ECG segment, which has a lowest level of noise relative to other ECG segments in the plurality of ECG segments;

    analyzing the lowest-noise ECG segment to detect one or more elevated ST segments therein;

    upon detection of the one or more elevated ST segments, generating an alert;

    presenting the lowest-noise ECG segment that triggered the alert to a user for review;

    receiving user feedback regarding whether the alert is a false positive; and

    adjusting an elevated ST segment detection algorithm as a function of the received user input such that elevated ST segments not indicative of ischemia or myocardial infarction are ignored.
