Patent ID: 11918814
Assignee: CARDIAC PACEMAKERS, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 12:
13. A system for pacing a heart, comprising:
an electrostimulation circuit configured to provide electrostimulation energy to an interventricular septum between left and right ventricles of the heart;
a cardiac event detector configured to:
receive physiological information of a patient including cardiac information and a His-bundle signal different than the cardiac information;
determine a presence or an absence of cardiac arrhythmia using the cardiac information; and
detect a conduction system activity from the His-bundle signal, including to detect the conduction system activity from the His-bundle signal using a first detection mode corresponding to a first sensitivity in response to the presence of the cardiac arrhythmia, and to detect the conduction system activity from the His-bundle signal using a second detection mode corresponding to a second sensitivity in response to the absence of the cardiac arrhythmia, the first sensitivity being higher than the second sensitivity; and
a control circuit configured to generate a control signal to the electrostimulation circuit to initiate electrostimulation of the interventricular septum based on the detected conduction system activity.
