Capture vs sensing pacemaker

WebSensing. When using the term sensing in talking about pacemakers, we mean the ability of the pacemaker to “see” a signal of the heart’s own rhythm. As the heart’s myocardium depolarises, it generates an electrical output. This signal travels up the pacemaker lead in contact with the myocardium, and reaches the IPG. In the event that the ...
