Pacemaker 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 کاملClinical Trials for Cardiac Pacing in Bradycardia
Since the first report of clinical application of cardiac pacing more than 50 years ago,1 it remains the only effective long-term treatment of symptomatic bradycardia. Although the indications for the use of implantable cardiac pacemakers have expanded significantly over the past several years, sick sinus syndrome (SSS) and atrioventricular (AV) conduction disorders continue to be the major ind...
متن کاملCardiac pacing in children.
Advances in pacemaker technology over the last 25 years have made cardiac pacing in infants and children a safe and practical therapy. Some of the technical challenges encountered with the first permanent pacemaker implantation in children during the early 1960s have been solved with miniaturized generators, lithium batteries, noninvasive programmability, and improved placement techniques. This...
متن کاملECGs and Pacemakers
Leadless pacemakers will most likely be the future of cardiac pacing. Leadless pacing employs a singlechamber system to pace only the right ventricle and is fully self-contained, which eliminates the need for leads. These systems, implanted by using a transcatheter sheath, are indicated for patients who need right ventricular pacing only. These devices enable patients to avoid lead-related comp...
متن کاملRecent Advances in Pacing and Defibrillation
Most current pacemaker and ICD systems involve placement of lead(s) transvenously into the heart, connected to a pulse generator. Vascular access may be difficult or limited in some patients, and intravascular leads can be associated with multiple complications such as infection, lead malfunction and vascular occlusion. Recent advances in pacing and ICDs include the development of subcutaneous ...
