Abstract
Various exemplary methods include altering conduction and/or operation of the AV node and/or AV bundle to help classify arrhythmias.
Claims19
A method comprising:
- detecting a first ventricular rate;
- stimulating a parasympathetic nerve associated with the atrio-ventricular node, wherein the stimulating occurs postinspiration only;
- detecting a second ventricular rate;
- and
- classifying the first ventricular rate based on the first ventricular rate and the second ventricular rate.
2 more elements
A method comprising:
- detecting a first ventricular rate;
- stimulating a parasympathetic nerve associated with the atrio-ventricular node;
- detecting a second ventricular rate;
- and
- classifying the first ventricular rate based on the first ventricular rate and the second ventricular rate;
- and
- wherein the stimulating includes stimulating at a site proximate to an epicardial plexus or subplexus.
4 more elements
A method comprising:
- stimulating a parasympathetic nerve associated with the atrio-ventricular node to thereby decrease conduction of the atrio-ventricular node;
- detecting a ventricular rate;
- repeating the stimulating and the detecting until the ventricular rate decreases;
- and
- classifying the cardiac activity as characteristic of a supraventricular arrhythmia.
2 more elements
A method comprising:
- detecting a first ventricular rate;
- delivering stimulation at a first site in an effort to decrease AV nodal conduction;
- detecting a second ventricular rate;
- and
- if the first ventricular rate exceeds the second ventricular rate, classifying the first ventricular rate as characteristic of a supraventricular arrhythmia;
- otherwise, delivering stimulation at a second site in an effort to decrease AV nodal conduction.
3 more elements
An apparatus comprising:

- means for detecting a second ventricular rate;
- and
- means for classifying the first ventricular rate based on the first ventricular rate and the second ventricular rate.
