Abstract
A system and method are provided for detecting dislodgment of a right atrial endocardial lead implanted within a heart right atrium wherein the lead includes an electrode. Heart activity of the right atrium of the heart, and heart activity of the right ventricle of the heart, and heart activity with the endocardial lead electrode are sensed during a time period. The sensed heart activity is stored in memory. The stored heart activity is analyzed to establish a first time window from the sensed heart activity of the right atrium and a second time window from the sensed heart activity of the right ventricle. The heart activity sensed with the endocardial lead electrode during the first time window is then compared to the heart activity sensed with the endocardial lead electrode during the second time window.
