Safety of mechanical lung vibrator and high-frequency chest wall oscillation in patients with cardiac implantable electronic device.

CPT may be safely applied to patients with CIED without compromising lead integrity or device function, except for unwanted increase in pacing rate caused by misdetection of chest wall vibration as patients' activity while using HFCWO. Deactivation of the accelerometer-based activity sensor may be needed when HFCWO is planned for CPT.
