St elevated myocardial infarction (stemi) detection in insertable cardiac monitor

A method of operating a patient management system, the method comprising:

• receiving, by signal processing circuitry of the patient management system, a cardiac signal of a patient, wherein the received cardiac signal is a frequency filtered cardiac signal produced from a broader frequency band cardiac signal sensed using an ambulatory medical device (AMD);
• restoring, using the signal processing circuitry, the received cardiac signal to the broader frequency band cardiac signal;
• and
• producing an alert of myocardial infarction when detecting an elevated ST segment in the restored broader frequency band cardiac signal.

A non-transitory computer readable storage medium including instructions that when performed by one or more processors of a medical device cause the medical device to perform operations including:

• receiving, by signal processing circuitry of the patient management system, a cardiac signal of a patient, wherein the received cardiac signal is a frequency filtered cardiac signal produced from a broader frequency band cardiac signal sensed using an ambulatory medical device (AMD);
• restoring, using the signal processing circuitry, the received cardiac signal to the broader frequency band cardiac signal;
• and
• producing an alert of myocardial infarction when detecting an elevated ST segment in the restored broader frequency band cardiac signal.
