Abstract Right ventricle perforation by pacemaker lead is rare but a life-threatening complication. It may present acutely within few hours of implantation as hemopericardium, dreaded cardiac tamponade, leading to acute hemodynamic deterioration; even death, if not address immediately. At times, it presents gradually with progressive decline in and requires surgical exploration. The authors rep...

INTRODUCTION Vegetative lead infection is an uncommon complication of permanent pacemaker implantation. The diagnosis is difficult using conventional imaging methods. CLINICAL PICTURE An elderly Indian woman with a history of diabetes mellitus developed Staphylococcus aureus infection after implementation of a permanent pacemaker. Following a non-diagnostic transthoracic echocardiogram, trans...

Superior vena cava (SVC) obstruction is an uncommon but serious complication associated with permanent pacemaker implantation. The mechanical stress associated with pacemaker wires may lead to vessel wall inflammation, fibrosis, and thrombus formation, and ultimately to venous stenosis and occlusion. The surgical treatment of pacemaker related SVC syndrome requires thoracotomy and carries signi...

Repeated implantation of pacemaker in the same patient is a common occurrence because of the increased longevity of patients. However, repeated lead fracture in the same patient and migration of the pacemaker lead into the pulmonary circulation is rare. We describe a 56-year-old gentleman who had undergone pacemaker implantations thrice due to repeated lead fractures (thrice) and also had migra...

OBJECTIVES We evaluated the incidence, predictors, and treatment of pacemaker syndrome in patients with sinus node dysfunction treated with ventricular-based (VVIR) pacing in the Mode Selection Trial (MOST). BACKGROUND Pacemaker syndrome, or intolerance to VVIR pacing, consists of cardiovascular signs and symptoms induced by VVIR pacing. METHODS The definition of pacemaker syndrome required...

BACKGROUND Though vasovagal syncope probably does not directly cause death, it is often associated with severe trauma and, when recurrent, significantly impairs the patient's quality of life. While drug therapy for vasovagal syncope is still controversial, recently two randomized studies revealed the efficacy of dual-chamber pacemaker implantation in decreasing recurrences in very symptomatic p...
