Abstract

The Endotak lead system and ICD has been used to treat patients with malignant ventricular arrhythmias. We analyzed the clinical characteristics of 1,053 patients who underwent implantation of the Endotak lead system with or without a subcutaneous patch. Group A consisted of 567 patients receiving the Endotak lead with a subcutaneous patch; group B consisted of 486 patients receiving the Endotak lead alone. The 2-year survivals from sudden death, cardiac death, and total death in groups A and B were 97.6%/98.2% (P = 0.38), 88.6%/92.7% (P = 0.09), and 84.7%/86.8% (P = 0.06), respectively. Minimum tested effective defibrillation energy at implantation was 17.2 +/- 5.2 J for group A and 15.8 +/- 5.1 J for group B (P < 0.01). The operative mortality was 1.8% in group A and 0.6% in group B (P = 0.09). The incidence of lead dislodgment, malfunction, and infection was 6.7% for group A and 3.5% for group B (P < 0.01). Sudden death survival was excellent in both groups with less lead complications in group B. The Endotak lead alone may be the preferred choice of lead configuration in those patients who have adequate defibrillation thresholds at implant.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
