Images in Emergency Medicine: Pacemaker Extrusion Causing Chest Pain
A 55-year-old Hispanic male had a pacemaker placed in Mexico approximately one year prior to presenting to the Emergency Department. He noticed minor discomfort in his left chest one month earlier but did not see a physician. The discomfort steadily increased and he saw a small piece of metal poking through the skin. He assumed it was a staple or something minor related to the surgery; however,...
متن کاملPacemaker Twiddler's Syndrome
A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. 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 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...
متن کاملPrediction of Extrusion Pressure in Vortex Extrusion Using a Streamline Approach
Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...
متن کاملPatient and pacemaker survival after pacemaker implantation.
One hundred thirty patients have had 244 pacemakers of five types implanted at Presbyterian-St. Luke’s Hospital in the past eight years. There has been I 0.50 probabilIty of successful unit function at only 12 months with epicardial units. All transvenous units used have had a 0.50 probabilIty of unit success at more than 17 months. This fact, combined with the lower frequency of early death wi...
