Syncope during pregnancy in a patient with permanent cardiac pacemaker, due to increased pacing threshold.
Journal Title: International Journal of Cardiovascular Practice - Year 2016, Vol 1, Issue 2
Abstract
A 22-year-old pregnant woman referred with syncope due to pacemaker malfunction. During the second trimester of pregnancy, the right ventricular (RV) lead pacing threshold increased and led to early generator depletion. We believe that this might happen due to lead micro-dislodgement or less probably effect of hormonal changes during pregnancy on electrode-myocardium interface.
The Correlation between Serum Level of N-Terminal Pro-B-type Natriuretic Peptide and Gensini Score in Patients with Acute Coronary Syndrome
Introduction: N-terminal pro-B-type natriuretic peptide (NT-proBNP) has emerged as an important biomarker for developing the diagnosis and prognosis of cardiovascular diseases, as several studies have shown that serum le...
Value of Admission HbA1c Level in Non-diabetic Patients With Unstable Angina
Introduction: There have been incompatible evidences about the prognostic value of HbA1c on the adverse outcomes in acute coronary syndrome. Also, these data are so limited in nondiabetic patients with unstable angina....
Frequency of HLA-B27 in Patients With Conductive System Disturbance and Implanted Permanent Pacemaker in Iran
Introduction: HLA-B27 is considered as one of the causes of heart conductive disorders. We studied the frequency of HLA-B27 among Iranian patients who had undergone permanent pacemaker implantation. Methods: This descri...
