Abstract
A medical device system including an intracardiac pacemaker is configured to receive by an implantable medical device sensing module a first cardiac signal using a first pair of electrodes implanted outside the cardiovascular system and identify a P-wave from the first cardiac signal. The system transmits a wireless trigger signal to the intracardiac pacemaker in response to identifying the P-wave. The intracardiac pacemaker delivers a pacing therapy in response to the trigger signal.
Claims21
A method for controlling automated delivery of therapeutic stimulation pulses by a medical device system including an intracardiac pacemaker implanted in a patient, the method comprising:
- acquiring by an implantable medical device sensing module a first cardiac signal using a first pair of electrodes selected from a plurality of available electrode pairs that are implanted outside the cardiovascular system, the plurality of available electrodes defining at least one sensing vector that is approximately parallel with a cranial-caudal axis of the patient;
- generating a first electrocardiogram (ECG) signal from the received first cardiac signal;
- identifying a P-wave from the ECG signal;
- transmitting a wireless trigger signal from the implantable medical device to the intracardiac pacemaker in response to identifying the P-wave;
- and
- delivering a pacing therapy by the pacemaker in response to the trigger signal.
An implantable medical device system, comprising:
- a first device comprising a sensing module coupled to a plurality of electrodes implanted outside the cardiovascular system of a patient and configured to:
- receive by the sensing module a first cardiac signal using a first pair of electrodes of the plurality of electrodes, the plurality of electrodes defining at least a first sensing vector that is approximately parallel with a cranial-caudal axis of the patient;
- generate a first electrocardiogram (ECG) signal based on the first cardiac signal;
- identify a P-wave using the first ECG signal;
- a trigger signal emitting device controlled by the first device to emit a wireless trigger signal in response to the identified P-wave;
- and
- an intracardiac pacemaker configured to detect the wireless trigger signal and deliver a pacing therapy in response to the wireless trigger signal.
A non-transitory, computer-readable storage medium storing a set of instructions that cause an implantable medical device system including an intracardiac pacemaker to perform a method, the method comprising:
- acquiring by an implantable medical device sensing module a first cardiac signal using a first pair of electrodes of a plurality of available electrode pairs that are implanted outside the cardiovascular system, the first pair of electrodes defining a sensing vector that is approximately parallel to a cranial-caudal axis of the patient;
- generating a first electrocardiogram (ECG) signal based on the first cardiac signal;
- identifying a P-wave from the first ECG signal;
- transmitting a wireless trigger signal from an emitting device to the intracardiac pacemaker in response to identifying the P-wave;
- and
- delivering a pacing therapy by the pacemaker in response to the trigger signal.
