Symptomatic bradycardia due to gastric distension is a rarely reported entity in the field of medicine. The mechanism of gastrointestinal distention that contributes to bradycardia is complex. A 75-year-old female with recurrent episodes of dizziness in the setting of gastric distension was found to have severe sinus bradycardia which resolved upon resolution of gastric distension. No structural or functional abnormality of heart was found. The patient was treated with permanent pacemaker implantation due to recurrent episodes of dizziness in the setting of sinus bradycardia...

Mitochondrial diseases are complex and rare clinical entities that can sometimes be diagnosed by their constellation of simple clinical signs. We describe a 24-year-old insulin-dependent diabetic women who was diagnosed with complete heart block and required permanent pacemaker implantation. Astute physical examination revealed opthalmoparesis, ptosis, and pigmentary retinopathy consistent with a diagnosis of Kearns-Sayre syndrome. When a young patient presents with complete heart block, a neurologic examination including funduscopy can identify Kearns-Sayre syndrome, which has far-reaching consequence for the index patient and offspring...

REVIEW
Andreas Schuchert
Implantable loop recorder with discontinuous ECG recording enables monitoring of heart rhythm over several years. Consequently, in patients with recurrent syncope it is possible to record an ECG during the next syncopal event to obtain symptom-ECG correlations. In patients with recurrent syncope of unknown origin, the implantation of a loop recorder leads to an earlier diagnosis and an asystole is more often detected as the cause of the recurrent syncope. In addition, the loop recorder identifies patients who will benefit from pacemaker implantation...

Twiddler's syndrome is an uncommon hardware complication involving the lead and pulse generators in cardiac pacemakers and defibrillators, deep brain stimulators, and vagal nerve stimulators. However, until very recently, it had not been reported in spinal cord stimulation (SCS). Considering the incidence of hardware complications of spinal cord stimulation, there may be an underreporting of Twiddler's syndrome due to lack of awareness. Two cases of Twiddler's syndrome as a hardware complication of SCS were identified between 2005 and 2015...

Background Severe brady-arrhythmias, requiring a permanent pacemaker (PPM), have been sparsely reported in systemic lupus erythematosus (SLE). The aim of this study was to describe the characteristics of such arrhythmias in a defined lupus cohort. Patients and methods The database of the Toronto Lupus Clinic ( n = 1366) was searched for patients who received a PPM. Demographic, clinical, immunological and therapeutic variables along with electrocardiographic (ECG) and echocardiographic findings (based on the last available test prior to PPM) were analyzed...

Swallow syncope is a rare dysautonomic syndrome characterized by temporary loss of consciousness upon swallowing solid foods or liquids, displaying primarily in individuals with an underlying structural or functional esophageal or cardiac pathology. However, the evidence also suggests that isolated vagal dysfunction or abnormal reactions of esophageal mechanoreceptors after mechanical irritation, demyelination, or trauma can potentially evoke  a cardioinhibitory response or vasodepression upon swallowing. We present a case of a 49-year-old otherwise healthy female patient who developed swallow syncope two weeks after whiplash neck injury acquired in a rear-end collision...

PURPOSE: Although most totally visually blind individuals exhibit nonentrained circadian rhythms due to an inability of light to entrain the circadian pacemaker, a small proportion retain photic circadian entrainment, melatonin suppression, and other nonimage-forming responses to light. It is thought that these responses to light persist because of the survival of melanospin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs), which project primarily to the circadian pacemaker and are functionally distinct from the rod and cone photoreceptors that mediate vision...

From 1993 to 2009, nearly 2.9 million pacemakers were implanted in the United States; the majority of which were dual chamber pacemakers. One of the major physiologic advantages of dual chamber pacing over single chamber ventricular pacing is atrioventricular synchrony, which prevents the pacemaker syndrome. However, patients who are pacemaker dependent or use right ventricle (RV) apical pacing more than 40% of the time are at a risk of developing heart failure from electromechanical dyssynchrony. Studies have also shown that RV pacing results in non-physiological activation of the left ventricle, leading to adverse clinical outcomes...

OBJECTIVES: When drainage of an anomalous pulmonary vein is high into the superior vena cava (SVC), traditional techniques of 1-patch or 2-patch repair may be challenging. The cavoatrial anastomosis technique (the Warden procedure) was developed to reduce the risk of sinus node dysfunction and SVC obstruction. Herein, we describe the outcomes of the Warden procedure in children at a single institution. METHODS: A retrospective study was conducted on all children with partial anomalous pulmonary venous drainage (PAPVD) undergoing the Warden procedure from 1996 to 2015...

Increased resting heart rate (HR) contributes to higher cardiovascular mortality and morbidity in the healthy as well as in people with cardiovascular diseases, possibly due to elevated blood pressure (BP) among other mechanisms. Data on the relationship between HR and central (aortic) BP remains controversial, however, and concerning β-blockers, it has been proposed that pharmacological HR lowering is associated with augmentation of central BP. We aimed to study the role of pharmacologically unaffected HR on central BP indices in sick sinus syndrome patients with a permanent cardiac pacemaker in the HR range from 40 to 90 bpm...

Twiddler's syndrome is the deliberate, inadvertent, or subconscious manipulation of an implantable generator within its subcutaneous pocket which can lead to malposition and fracture of the associated lead.1 The syndrome is well-recognized in patients with pacemakers, implantable cardioverter-defibrillators, deep brain stimulators and more recently in intrathecal drug delivery devices.1-3 Here we present an instance of Twiddler's syndrome after sacral neuromodulation [SNM].

Background: Brucellosis is a bacterial infection, caused by the nonmotile gram-negative aerobic coccobacilli. The clinical manifestation of brucellosis is variable, ranging from mild disease to severe disease. The gold standard test to confirm the diagnosis of brucellosis is assaying blood, bone marrow, or other body fluids or by tissue culture. Preferred first-line treatment in adults with uncomplicated, nonlocalized disease consists of doxycycline-aminoglycoside combination. The recommended duration of treatment is 6 weeks...

PURPOSE: To identify whether long-term symptom relief and stent patency vary with the use of covered versus uncovered stents for the treatment of benign SVC obstruction. METHODS AND MATERIALS: We retrospectively identified all patients with benign SVC syndrome treated to stent placement between January 2003 and December 2015 (n = 59). Only cases with both clinical and imaging follow-up were included (n = 47). In 33 (70%) of the patients, the obstruction was due to a central line or pacemaker wires, and in 14 (30%), the cause was fibrosing mediastinitis...

REVIEW
Kalaimani Elango, Anne B Curtis
Clinical trials have demonstrated the benefits of cardiac implantable electrical devices, which include pacemakers, implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT), with respect to key clinical outcomes and survival. Women more often require permanent pacing for sick sinus syndrome, whereas atrioventricular block is more common in men. Women appear to have a higher incidence of complications with pacemaker implantation, as well as with ICD and CRT implantation. The indications for ICDs and CRT do not have any distinctions based on sex, and outcomes are comparable in men and women...

: The purpose of this two-part consensus document is to provide specific suggestions (based on an extensive literature review) on appropriate pacemaker setting in relation to patients' clinical features. In part 2, criteria for pacemaker choice and programming in atrioventricular blocks and neurally mediate syncope are proposed. The atrioventricular blocks can be paroxysmal or persistent, isolated or associated with sinus node disease. Neurally mediated syncope can be related to carotid sinus syndrome or cardioinhibitory vasovagal syncope...

A left atrial appendage occluder device (Watchman) and leadless pacemaker (Micra) was implanted from a single right femoral vein access in a 73-year-old female patient with persistent atrial fibrillation and symptomatic tachy-brady syndrome and unable to take oral anticoagulants. Standard methods of implantation were followed for both procedures. The Watchman device was implanted first followed by dilatation of the same venous access site in order to implant Micra transcatheter pacing system. The patient tolerated the procedures well and there were no complications...
