Abstract
Terminating supraventricular arrhythmias through parasympathetic nerve stimulation. The method comprises detecting a supraventricular arrhythmia, stimulating a parasympathetic nerve and determining whether the supraventricular arrhythmia terminated or worsened. Various exemplary methods include delivering one or more stimulation pulses during postinspiration and/or in response to one or more cardiac events.
Claims37
A method comprising:
- detecting a supraventricular arrhythmia;
- providing an electrode portion of a lead extending through a wall of a great cardiac vein and along nerves emanating from a ventral right atrial subplexus;
- stimulating at a vessel emanating from an epicardial subplexus according to one or more stimulation parameters using the electrode portion;
- determining whether the supraventricular arrhythmia terminated, became more complex or became less complex;
- halting the stimulating if the supraventricular arrhythmia terminated;
- halting the stimulating if the supraventricular arrhythmia became more complex;
- and
- repeating the stimulating if the supraventricular arrhythmia became less complex.
