In adults, permanent pacemakers are most commonly implanted with access to the heart by way of the subclavian–superior vena cava venous system. Rare, but possible,acute complications of transvenous pacemaker implantation include infection.In this case pacemaker or the lead was the source of infection .When an implanted device is suspected of being the source of bacteremia ,
the strength of evidence that the device is infected is based on the assessment of the specific pathogens (confirmed by the recovery of the same species of microorganism from peripheral-blood cultures ) and the patient’s response to antimicrobial therapy if the device is initially retained.Intrinsic (during the manufacturing process)contamination of the device is rare.The incidence of infection after initial device implantation is usually less than 1%.Treatment of device-related septicemia requires removal of the entire infected pacing system, device, and leads.
