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.

Abstract

Introduction: Prognosis of the patients with beta blocker or calcium channel blocker induced AV block is not well known to date.Methods: All patients with symptomatic second-degree or third-degree atrioventricular block (AV) referred to our institution during one year were recuited prospectively and classified in two groups based on drug consumption (beta blocker/calcium channel blocker versus none). They were followed for six months and then collected data was analyzed.Results: The study included 49 patients, 28 patients (age 60.1 ± 20, 19 male) did not use any beta blocker or calcium channel blocker (No- DU group) and other 21 patients (age 73.5 ± 10.4, 7 male) receivd beta blocker, calcium channel blocker or both at the time of AV block (DU group). No-DU group was significantly younger than DU group. The most common atrial rhythm in both groups was sinus. There was no significant difference in QRS wideness or ventricular rate. AV block regressed in 43% of the DU group after discontinuation of drug for five half-life, but, Mobitz type 2 or complete AV block occurred again during six months in 50% of them without  consumption of the culprit drug.Conclusions: More than two third of the patients who developed AV block on beta blocker and/or calcium channel blocker needed permanent pacemaker in six months of follow- up, so we concluded that the development of AV block was not as benign as it seems in these patients.

Abstract

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.Methods: In this cross-sectional study, HbA1c level of 231 nondiabetic patients admitted with unstable angina, was measured using high performance liquid affinity chromatography (HPLC) at admission. Then transthoracic echocardiography (TTE) was performed for evaluation of ejection fraction (EF) using Simpson method.Results: Our data revealed that HbA1c was significantly higher in patients with EF≤ 50% in comparison with EF>50% group (P value=0.01).Conclusions: HbA1c may be a helpful prognostic marker in nondiabetic patients admitted in emergency department with diagnosis of unstable angina.

Different types of supraventricular tachycardia have been reported in patients with history of surgical repair of Tetralogy of Fallot. This report presents appearance of focal atrial tachycardia during radiofrequency ablation of the cavotricuspid isthmus
Venous Obstruction Following Pacemaker or Implantable Cardioverter-Defibrillator Implantation, Mini Review Akbarzadeh, Mohammad Ali

Abstract

Venous obstruction is relatively frequent following permanent pacemaker or implantable cardioverter-defibrillator (ICD) implantation. However, most of them are asymptomatic. Although the exact risk factor for this complication is not known, number of leads, heart failure and infection may prone the patient to this complication. The goal standard for detection of vein stenosis is venography; however, ultrasound sonography has an acceptable accuracy. Anticoagulant therapy may be considered for symptomatic patients. For device upgrading, non-functional leads removal, venoplasty and rarely surgical treatment may be indicated.
