Problems solved by technology

However, in contrast to conventional pacemakers, the LP system does not include a single controller (e.g., a processor) located within the pacemaker's housing to obtain sensed signals from electrodes physically connected to the pacemaker's three leads. )

Embodiment Construction

[0046] Certain embodiments of the present technology relate to implantable systems and methods for use therewith that may be used to perform cardiac synchronization therapy (CRT). For example, certain embodiments of the present technology relate to implantable systems and methods for use therewith that can be used to perform DDD or DDI pacing using three LPs, wherein one of the LPs (LP1) is implanted in the patient's RA lumen chamber (or on the RA chamber), one of the LPs (LP2) is implanted in the patient's RV chamber (or on the RV chamber), and one of the LPs (LP3) is implanted in the patient's LA chamber (or on the LA chamber). chamber). More specifically, according to certain embodiments of the present technology, LP1 is implanted in (or on) the RA chamber of the patient and used to perform ADD pacing, implanted in the patient's RV chamber (or on the RV chamber LP2 above) is used to perform VDD pacing, and LP3 implanted in (or on) the LV chamber of the patient is used to p...

Abstract

Embodiments of the present technology described herein are directed to implantable systems for performing cardiac resynchronization therapy (CRT), and a method and leadless pacemakers for use therewith. Such a system can include a first leadless pacemaker configured to be implanted in or on the right atrial (RA) chamber and selectively pace the RA chamber, a second leadless pacemaker configured tobe implanted in or on the right ventricular (RV) chamber and selectively pace the RV chamber, and a third leadless pacemaker configured to be implanted in or on the left ventricular (LV) chamber andselectively pace the LV chamber, wherein one of the leadless pacemaker is designated a master leadless pacemaker. In some embodiments, the master leadless pacemaker determines a VV delay and an AV delay and coordinates CRT using such delays.

Description

technical field [0001] Embodiments of the present technology generally relate to methods, systems, and devices that can be used to provide cardiac resynchronization therapy (CRT) and that can be used to select CRT parameters. Background technique [0002] Heart failure (HF) is a debilitating, terminal disease in which abnormal function of the heart results in insufficient blood flow to meet the needs of the body's tissues. Typically, the heart loses propulsion because the heart muscle loses its ability to stretch and contract. Often, the ventricles do not fill sufficiently with blood between heartbeats, and the valves that regulate blood flow may become leaky, causing regurgitation, or regurgitation, of blood. Damage to arterial circulation deprives vital organs of oxygen and nutrients. May cause fatigue, weakness and inability to perform daily tasks. [0003] Not all HF patients develop debilitating symptoms immediately. Some people may live actively for many years. Ho...
