A transcutaneous cardiac pacing system has one or more cutaneous electrodes suitable for attachment to a human patient and a transcutaneous pacing system coupled to supply pacing pulses to the patient via the cutaneous electrodes. The pacing pulses are effective to stimulate cardiac activity in the patient. The transcutaneous cardiac pacing system also includes a transcutaneous electrical nerve stimulation system coupled to supply nerve stimulation pulses to the patient via the same electrodes. The nerve stimulation pulses are effective to mitigate any discomfort that the patient might experience from the transcutaneous pacing pulses. The system thereby provides effective and tolerable emergency cardiac pacing without introduction of intravenous drugs or sedation of the patient.

A computer controls a video display having a display screen for displaying ECG heartbeats superimposed over one another. The ECG data is collected during Holter monitoring and stored in a memory. The Holter monitor preliminarily classifies each beat to a morphology. A representative sample of each morphology is presented in a display window. Each sample can be overlaid with any other selected sample, in different colors, in a compare window having an enlarged scale from the display windows. After comparison, different morphologies can be merged and a selected beat classification can be reclassified to another morphology.
