Abstract
A method and system for treating cardiac arrhythmias which includes inserting one or more electrodes into a patient's neck, and connecting the electrodes to the vagus nerve in the patient's neck. A cardiac monitoring device detects a cardiac arrhythmia. A controller connected to an electrical power source provides electrical power to the electrodes to apply electrical stimulation to the vagus nerve when a cardiac arrhythmia is detected.

1-14. (canceled)
A method for treating cardiac arrhythmias, comprising:
- inserting an electrode into a patient's neck;
- connecting the electrode to a vagus nerve in the patient's neck;
- detecting a cardiac arrhythmia;
- and
- initiating electrical power to the electrode using a controller connected to an electrical power source to apply electrical stimulation to the vagus nerve when a cardiac arrhythmia is detected during a cardiac arrhythmia, wherein no cardiac electrical stimulation is applied, wherein the electrode is configured to apply electrical stimulation to the vagus nerve during ventricular tachycardia or ventricular fibrillation.
A system for treating cardiac arrhythmias, comprising:
- an electrode having a distal end insertable into a patient's neck and connectable at a distal end to a vagus nerve;
- a controller connected to a proximal end of the electrode, wherein the controller is connected to an electrical power source for providing electricity to the electrode for electrically stimulating the vagus nerve, wherein the electrical stimulation to the vagus nerve is applied during a cardiac arrhythmia;
- and
- a cardiac monitoring device configured to sense the heart's electrical activity, wherein no cardiac electrical stimulation is applied, wherein the system is configured to apply electrical stimulation to the vagus nerve during ventricular tachycardia or ventricular fibrillation.
A method for treating cardiac arrhythmias, comprising:
- inserting two electrodes into a patient's neck;
- connecting the electrodes to a vagus nerve in the patient's neck;
- detecting a cardiac arrhythmia;
- and
- initiating electrical power to the electrodes using a controller connected to an electrical power source to apply electrical stimulation to the vagus nerve when a cardiac arrhythmia is detected during a cardiac arrhythmia, wherein no cardiac electrical stimulation is applied, wherein the electrodes are configured to apply electrical stimulation to the vagus nerve during ventricular tachycardia or ventricular fibrillation.
