System and method for administering transcutaneous cardiac pacing with transcutaneous electrical nerve stimulation
First Claim
1. A method for administering cardiac pacing comprising the following steps:
- applying transcutaneous pacing to a patient to stimulate cardiac activity; and
applying transcutaneous electrical nerve stimulation to the patient concurrently with application of said transcutaneous pacing to mitigate discomfort in the patient.

Abstract
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.

16. A circuit for use in a cardiac pacing system, the circuit comprising:
-
a first input to receive a pacing signal; a second input to receive a non-modulate, analog nerve stimulation signal; at least one output to output at least one of the pacing signal or the nerve stimulation signal; an analog-to-PWM converter coupled to the second input to convert the nerve stimulation signal from a non-modulated analog signal to a pulse width modulated signal; and coordinating circuitry connected between the inputs and the output to coordinate output of the pacing signal and the nerve stimulation signal.
