Recording of Peak Endocardial Acceleration in the Atrium

Background: The important role played by peak endocardial acceleration (PEA or sonR) in hemodynamic monitoring of cardiac resynchronization therapy (CRT) was recently highlighted in several studies with the sensor embedded in a right ventricular (RV) lead tip. This study examined the short‐ and long‐term reliability of a right atrial (RA) sonR sensor.
