Herein is described a device and methods-of-use to treat multiple possible causes of sudden neurological dysfunction related to cardiac, cerebrovascular, or brain electrical abnormalities. The device can be employed so as to treat cardiac dysfunction such as arrhythmia and subsequently related dysfunction of the central nervous system such as stroke and seizure. Alternatively, the device can be employed so as to treat cardiac dysfunction simultaneous with treatment of dysfunction of the central nervous system. Finally, the device can be employed so as to augment the effectiveness of treating cardiac dysfunction, namely the restoration of cardiac output and blood flow to the brain, by dilating the arteries of the brain.
