Recurrent Pneumonia Related To Pacemaker Lead Infection

Lead endocarditis is an infrequent and serious complication of pacemaker implantation. Its clinical presentation is in most of the cases atypical. When dealing with patients with persistent fever and implanted cardiac device, high suspicion is needed for early diagnosis. In our case, a young patient with an intracardiac device implanted was treated twice for pneumonia before the diagnosis of lead endocarditis was established according to Duke's criteria. The contribution of transesophageal echocardiography in diagnosis was extremely important.

Delayed perforation of right ventricle with cardiac tamponade: a complication of pacemaker implantation

We report a case of delayed cardiac tamponade that resulted from pacemaker implantation in the emergency room of a large urban hospital. A 19-year-old male patient with a pacemaker implanted 10 days earlier suffered from delayed perforation of the right ventricle with cardiac tamponade. A review of the literature revealed that cardiac tamponade is a rare complication of pacemaker implantation. Pacemakers should only be implanted by physicians with relevant experience, and emergency room physicians should be aware of the possibility of the associated complications and be prepared to treat them.

Impact of continuous quality improvement on selection of pacing mode and rate of complications in permanent pacing.

OBJECTIVE: To improve pacing mode selection and to reduce complications of pacing using continuous quality improvement. DESIGN: Criterion standard study. Comparison of implantations from 1992-94 with preset standards. Implementation of...

Feasibility of Long‐Term Electrocardiographic Monitoring with an Implanted Device for Syncope Diagnosis

Patients with infrequent recurrent syncope undiagnosed after extensive noninvasive and invasive testing pose a diagnostic and therapeutic dilemma. The purpose of this pilot study was to assess the feasibility of using an implanted, long-term monitor as an aid to diagnosis in these patients. This was done using commercially available pacemakers with monitoring functions. Sixteen patients (eight males and eight females), aged 59.7 +/- 17 years who had unexplained syncope despite a 12-lead electrocardiogram, repeated Holter monitoring, exercise testing, echocardiography, an electrophysiological study, and a tilt test (n = 6), were entered into the study. Patients had experienced a mean of 3.1 +/- 1 episodes of syncope in the 12 months prior to the study. All provided a history suggestive of Stokes-Adams attacks and were referred for consideration of pacemaker implantation. Two patients had ischemic heart disease and one patient had a long QT interval. Patients had an Intermedics Nova II or Medtronic Quintech DPG pulse generator capable of recording sensed and paced events implanted with a single right ventricular lead. Syncope or presyncope occurred in ten patients (62%) 4.9 +/- 4.2 months after pacemaker implantation. Bradycardia was detected in six patients and four patients had no arrhythmia. In addition to bradycardia, one patient also had tachycardia detected. Pacing therapy resulted in symptom relief in all six patients with syncope or presyncope due to bradycardia. Complications of pacemaker implantation (lead insulation failure) occurred in two patients. One of these patients subsequently had an infection of the generator pocket with associated systemic sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)
