Respiratory sinus arrhythmia (rsa) pacing mode activation

A method comprising:

• sensing one or more parameters of a patient;
• determining that one or more criteria for activation of a respiratory sinus arrhythmia (RSA) mode are satisfied based on the one or more parameters of the patient;
• and
• delivering cardiac pacing pulses according to the RSA mode based on the determination, wherein delivery of the cardiac pacing pulses according to the RSA mode includes increasing a rate of the cardiac pacing pulses during an inspiration phase of a respiration cycle of the patient, and decreasing a rate of the cardiac pacing pulses during an expiration phase of the respiration cycle of the patient.

A non-transitory computer-readable storage medium comprising program instructions that, when executed by processing circuitry of a device, cause the processing circuitry to:

• control sensing circuitry of the device to sense one or more parameters of a patient;
• determine that one or more criteria for activation of a respiratory sinus arrhythmia (RSA) mode are satisfied based on the one or more parameters of the patient;
• and
• control therapy delivery circuitry of the device to deliver the cardiac pacing pulses according to the RSA mode based on the determination, wherein delivery of the cardiac pacing pulses according to the RSA mode includes increasing a rate of the cardiac pacing pulses during an inspiration phase of a respiration cycle of the patient, and decreasing a rate of the cardiac pacing pulses during an expiration phase of the respiration cycle of the patient.
