1. A device comprising:
a housing configured to be positioned external to a patient; and
a waveform generator configured to generate an alternating current (AC) and an electrical shock, the waveform generator being disposed in the housing and the waveform generator is configured to be connected electrically to at least one electrode configured to be positioned externally on the patient;
wherein the electrical shock is at least 400 volts (V), and
wherein the AC has a frequency in a range between 50 Hz to 20 kHz, has a duration, and includes a ramped amplitude waveform defined by a gradually increasing peak-to-peak amplitude of the AC during at least sixty percent of the duration.
