Background: Pacemaker lead dislodgement may cause malfunction in the pacing system, which may lead to severe adverse events. For patients with sick sinus syndrome but normal atrioventricular conduction, atrial lead dislocation may cause excessive unnecessary ventricular pacing, resulting in nonphysiological pacing leading to heart failure. TheThe pacemaker-twiddler’s syndrome refers to the permanent malfunction of a pacemaker resulting from manipulation of the pulse generator within its skin pocket [1]. This leads to a rotation of the device, coiling of the lead and its dislodgement, leading to pacemaker failure.Reel's syndrome is a rare cause of pacemaker failure, resulting from the dislodging of pacing electrodes by manipulation of the pulse generator by the patient. We describe here an intriguing case of pacemaker lead dislodgement by a novel and frequently underdiagnosed mechanism that mimicked the fluoroscopic diagnosis of reel's …Late lead perforation can cause haemorrhagic pericardial effusion. ... (2007) Prevalence and characterization of asymptomatic pacemaker and ICD lead perforation ...Pacemaker lead position and gross lead integrity may be further evaluated by anteroposterior (AP) and lateral chest X-ray images. ... Lead dislodgement may be due to inadequate fixation to the cardiac tissue, inadequate lead redundancy, loose fixation of the lead in the suture sleeves, or patient-related causes (such as non-compliance with ...Pacemakers consist of a pulse generator or can, which contains the battery and electronics, and leads, which travel from the can to contact the myocardium, to deliver a depolarizing pulse and to sense intrinsic cardiac activity (Figure 2).Insulation materials separate the conductor cables and the lead tip electrodes. Depending on the relationship …identified causes of undersensing.3,4 As with failure to capture, the onset of undersensing relative to the time of device implantation helps identify the cause. Undersens-ing occurring shortly after implantation may be due to lead dislodgement or malposition or to cardiac perfora-tion. If it occurs later, it could be due to battery deple-Lead dislodgement/fracture (requires repositioning or replacement of lead). ... Since the pacing lead is in the right ventricle causing this chamber to get ...Jan 14, 2021 · Pacemaker lead dislodgement causes malfunctions in the pacing system. Late dislodgement is defined as dislodgement occurring more than 6 weeks after pacing system implantation . Classification of lead dislodgement includes macro-dislodgement and micro-dislodgement. The pacemaker rotates on its long axis, resulting in dislodgement of pacing leads. Can result in diaphragmatic or brachial plexus pacing (e.g. arm twitching) depending on extent of lead migration. ECG in Pacemaker Malfunction. Normal pacemaker rhythms can result in absent pacing activity, irregular pacing and absence of pacing spikes.There has been a growing use of pacemakers, and one unusual complication is the displacement of the pacemaker lead [ 1 ]. Patients present with a range of …Introduction. Pacemaker lead macrodislodgement is an unusual occurrence and is typically thought to be caused by Twiddler’s syndrome, 1 Reel syndrome, 2 or trauma to the pacemaker system, 3 all of which are mechanisms for lead dislodgement evolving from manipulation of the generator and/or lead. In this report, we postulate the cause of …This case highlights the importance of considering pacemaker complications causing non-cardiac symptomatology and a structured approach to undifferentiated neuromuscular presentations in patients with PPMs should consider lead dislodgement as a differential diagnosis. ExpandOnce correct lead positioning is confirmed, the lead is affixed to the endocardium either passively with tines (like a grappling hook) or actively via a helical screw located at the tip. The screw at the tip of the pacemaker is extended or retracted by turning the outer end of the lead with the help of a torque device.Early diagnosis of defibrillation lead dislodgement. JACC Clin Electrophysiol. 2018; 4:1075–1088. doi: 10.1016/j.jacep.2018.03.015 Crossref Medline Google Scholar; 22. Kreis DJ, LiCalzi L, Shaw RK. Air entrapment as a cause of transient cardiac pacemaker malfunction. Pacing Clin Electrophysiol.Congestive heart failure and implantation of right atrial (RA) lead at RA free wall or septum were significant factors for the incidence of lead dislodgement and lead revision. The …Twiddler's syndrome, Lead dislodgement, Pacemaker malfunction Introduction. Twiddler's syndrome was first described by Bayliss, et al. in 1968, when a patient manipulated and rotated the pulse generator in the pocket resulting in lead dislodgement, diaphragmatic stimulation, and loss of capture . It occurs because of unintentional or deliberate ...In a review article, the most common complications reported with passive fixation leads were failure of venous access (15%), failure to place a lead (10%), and sepsis (9%). 11 Hyman et al. studied 1,022 patients at the Mayo Clinic who required conventional temporary pacing. 9 Lead dislodgement occurred in 17.9% of patients and was the …Twiddler' syndrome, reel syndrome, and ratchet syndrome are rare yet dangerous phenomena of pacemaker lead dislodgement. Twiddler's syndrome was first reported by Bayliss . In this case report, we describe an interesting case of pacemaker lead dislodgement by unconscious manipulation of the device pocket by a patient who presented eight months ...Lead revision or replacement: In cases of lead dislodgement or damage, a revision or replacement of the leads may be necessary to restore proper function. Battery replacement: If battery depletion is the cause of the malfunction, the pacemaker's battery will be replaced.Jan 14, 2021 · Pacemaker lead dislodgement causes malfunctions in the pacing system. Late dislodgement is defined as dislodgement occurring more than 6 weeks after pacing system implantation . Classification of lead dislodgement includes macro-dislodgement and micro-dislodgement. To minimize the risk of perforation, the surgeon should abstain from excessive advancement of the helix during lead fixation, excessive pressure on the lead, excessive loop, and forced dislodgement of the lead with an extended screw for instance due to dislocation of the atrial lead during the insertion of a ventricular lead, which should ...All leads are involved, at any time from implantation, and frequently damaged. In the past few years, a reel syndrome was also observed: retraction of pacemaker leads into pocket without patient manipulation, owing to lead circling the generator. In other cases, a ‘ratchet’ mechanism has been postulated.

CT scan of the patient does not usually cause problems in the pacemakers. Therefore, the presence of an implanted pacemaker should not hinder such investigative imaging modality. In rare cases, it might …What causes pacemaker lead dislodgement? First described in 1968, refers to permanent malfunction of a pacemaker due to the patient’s manipulation of the pulse generator. The patient, inadvertently or deliberately, turns and rotates the generator on its long axis and, because of traction, causes the lead displacement.It is caused by conscious or unconscious manipulation at the implantation site by the patient with the result of device malfunction. It results in lead ...L ead displacement is a common complication of pacemaker device implantation, often resulting in prolonged hospital stays and increased costs. The frequency of long-term lead displacement ranges between 1.8% and 8.0%. In our case, the patient did not present any symptoms and the lead displacement was seen at a relatively late stage.However, lead dislodgement can occur at any time - months or years - after the procedure. Infections. ... A dog with a pacemaker implant can no longer wear collars and neck leads because they may damage the pacemaker or cause it to get dislodged. Instead, a chest harness should be worn. A harness keeps pressure off the dog’s neck …

To minimize the risk of perforation, the surgeon should abstain from excessive advancement of the helix during lead fixation, excessive pressure on the lead, excessive loop, and forced dislodgement of the lead with an extended screw for instance due to dislocation of the atrial lead during the insertion of a ventricular lead, which should ...Early diagnosis of defibrillation lead dislodgement.
