Abstract
An implantable medical device is provided for detecting transportless ventricular rhythm of a heart lacking atrial transport and comprises a housing, sensors configured to be located proximate to a heart, a sensing module to sense cardiac signals representative of a rhythm originating from the heart and a rhythm detection module. The rhythm detection module determines a change in AV association and identifies a potential ventricular complex with loss of atrial transport (VCLAT) based on the change in AV association.
Claims10
An implantable cardiac stimulation device for treating a transportless ventricular rhythm, comprising:
- a housing;
- sensors configured to be located proximate to a heart;
- a sensing module to sense cardiac signals representative of a rhythm originating from the heart;
- a rhythm detection module to identify at least one of an accelerated junctional rhythm (AJR) and an accelerated idioventricular rhythm (AIVR);
- and
- a therapy control module to deliver an AJR-based therapy when the rhythm detection module identifies an AJR and to deliver an AIVR-based therapy when the rhythm detection module identifies an AIVR, wherein the AJR-based therapy differs from the AIVR-based therapy.
A method for treating a transportless ventricular rhythm, comprising:
- sensing cardiac signals representative of a rhythm originating from the heart;
- identifying at least one of an accelerated junctional rhythm (AJR) and an accelerated idioventricular rhythm (AIVR);
- delivering an AJR-based therapy when the rhythm detection module identifies an AJR;
- and
- delivering an AIVR-based therapy when the rhythm detection module identifies an AIVR, wherein the AJR-based therapy differs from the AIVR-based therapy.
