Left atrial function and atrial natriuretic factor/cyclic guanosine monophosphate changes in DDD and VVI pacing modes.
Left atrial systolic function and the plasma of atrial natriuretic factor (ANF) and cyclic guanosine monophosphate (cGMP) were investigated as possible markers for the development of pacemaker syndrome during VVI pacing. Patients who developed pacemaker syndrome during VVI pacing had a significant decrease in left atrial emptying fraction and a substantial increase in ANF and cGMP plasma levels.
