1. A computer-implemented method, comprising:
identifying, by one or more processors, a periodic component of an electrical waveform and a previously-assigned classification associated with the periodic component of the electrical waveform, wherein the electrical waveform represents electrical activity in a patient's heart;
analyzing, by one or more of the processors, a corresponding periodic component of a hemodynamic waveform that represents hemodynamic activity in the patient's cardiovascular system, wherein the corresponding periodic component is causally related to the periodic component of the electrical waveform;
classifying, by one or more of the processors, the corresponding periodic component of the hemodynamic waveform with the previously-assigned classification in response to a determination, based on the analyzing, that the previously-assigned classification also applies to the corresponding periodic component;
identifying, by one or more of the processors, an artifact classification assigned to another periodic component of the electrical waveform deemed an artifact;
analyzing, by one or more of the processors, another corresponding periodic component of the hemodynamic waveform that is causally related to the another periodic component of the electrical waveform;
classifying, by one or more of the processors, the another corresponding periodic component of the hemodynamic waveform with one or more classifications in response to a determination, based on the analyzing, that a delta between the another corresponding periodic component of the hemodynamic waveform and another previous periodic component of the hemodynamic waveform satisfies a threshold;
reclassifying, by one or more of the processors, the another periodic component of the electrical waveform with the one or more classifications; and
updating, by one or more of the processors, in a database of hemodynamic templates, a hemodynamic template associated with the previously-assigned classification to include one or more features of the corresponding periodic component of the hemodynamic waveform.
