He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...
متن کاملControl of intrinsic pacemaker frequency and velocity of colonic migrating motor complexes in mouse
The mechanisms that control the frequency and propagation velocity of colonic migrating motor complexes (CMMCs) in mammals are poorly understood. Previous in vitro studies on whole mouse colon have shown that CMMCs occur frequently (~every 1-3 min) when the colon is devoid of all fecal content. Consequently, these studies have concluded that the generation of CMMCs and the frequency which they ...
متن کاملPacemaker dependency after pacemaker implantation.
BACKGROUND Pacemaker dependency (PD) can be defined as the risk of serious injury or death from sudden pacemaker failure, an event more dangerous than progressive rate decrease. The aim of this study was to evaluate the incidence of PD during long-term follow-up after pacing system implantation. METHODS AND RESULTS The study included 3638 patients (mean age 65.3 +/- 10.2 years). Indications f...
