Why the study?
Does QT sensing rate responsive pacing provide physiological heart rate responses during febrile episodes of subacute bacterial endocarditis?
Does QT sensing rate responsive pacing provide physiological heart rate responses during febrile episodes of subacute bacterial endocarditis?
QT sensing rate responsive pacemakers can provide appropriate physiological heart rate increases during febrile episodes such as subacute bacterial endocarditis.
May support QT-sensing pacing for physiological responses during fever in endocarditis; hypothesis-generating case report requiring confirmation.
A 63-year-old woman treated with a QT sensing rate responsive pacemaker following aortic valve replacement developed late subacute bacterial endocarditis. During febrile periods, associated with systemic upset, pacing was physiological as evidenced by an increased heart rate during pyrexia and a decrease when afebrile.
