Mutations in the cardiac sodium channel gene SCN5A may result in various arrhythmia syndromes such as long QT syndrome type 3 (LQTS), Brugada syndrome (BrS), sick sinus syndrome (SSS), cardiac conduction diseases (CCD) and possibly dilated cardiomyopathy (DCM). In most of these inherited cardiac arrhythmia syndromes the phenotypical expression may range from asymptomatic phenotypes to sudden cardiac death (SCD). A 16-year-old female died during sleep. Autopsy did not reveal any explanation for her death and a genetic analysis was performed...

A cell-sourced biological pacemaker is a promising therapeutic approach for sick sinus syndrome (SSS) or severe atrial ventricular block (AVB). Adipose tissue-derived stem cells (ATSCs), which are optimal candidate cells for possible use in regenerative therapy for acute or chronic myocardial injury, have the potential to differentiate into spontaneous beating cardiomyocytes. However, the pacemaker characteristics of the beating cells need to be confirmed, and little is known about the underlying differential mechanism...

Our first case is an 84-year-old female diagnosed with sick sinus syndrome. She underwent implantation of dual chamber permanent pacemaker without complications. On the 8(th) day status-postimplantation, she returned to the emergency department (ED) with moderately severe left anterior chest pain and significant ecchymosis. She was given an initial diagnosis of shingles and discharged. Two days later, she returned to the ED with increasing chest pain, dyspnea, nausea, and vomiting. Lead migration and cardiac perforation was confirmed by chest X-ray and computed tomography (CT), respectively...

Sick sinus syndrome (SSS) encompasses a group of disorders whereby the heart is unable to perform its pacemaker function, due to genetic and acquired causes. Tachycardia‑bradycardia syndrome (TBS) is a complication of SSS characterized by alternating tachycardia and bradycardia. Techniques such as genetic screening and molecular diagnostics together with the use of pre-clinical models have elucidated the electrophysiological mechanisms of this condition. Dysfunction of ion channels responsible for initiation or conduction of cardiac action potentials may underlie both bradycardia and tachycardia; bradycardia can also increase the risk of tachycardia, and vice versa...

BACKGROUND: Sinus bradycardia includes pathologic sick sinus syndrome (SSS) and physiologic bradycardia such as athletes' heart. Pacemaker implantation is indicated for patients with symptomatic SSS; however, the indication remains difficult to determine in those with mild and/or unspecific symptoms. The sympathetic tone is increased in response to reduced cardiac output in SSS, whereas excessive vagal tone has been seen in physiological bradycardia. We sought to determine if cardiac iodine-123-metaiodobenzylguanidine scintigraphy ((123) I-MIBG) was useful in differentiating pathologic from physiologic sinus bradycardia...

A 21-year-old woman with Peuts-Jeghers syndrome (PJS) was referred to our hospital for gastrointestinal surveillance. She had been diagnosed as having PJS from a young age based on her family history and the presence of mucocutaneous pigmentation on her lips and oral mucosa. Her mother and brother had PJS harboring an entire deletion of the STK11 gene. She had tetralogy of Fallot, atrial tachycardia, sick sinus syndrome, and mental retardation in her past history. Esophagogastroduodenoscopy identified a protruded lesion with a depressed area that occupied the lumen half-circumferentially in the duodenal second portion and also showed a 10-mm protruded lesion on the anterior wall of the lower gastric body...

There are possibly millions of mold species on earth. The vast majority of these mold spores live in harmony with humans, rarely causing disease. The rare species that does cause disease does so by triggering allergies or asthma, or may be involved in hypersensitivity diseases such as allergic bronchopulmonary aspergillosis or allergic fungal sinusitis. Other hypersensitivity diseases include those related to occupational or domiciliary exposures to certain mold species, as in the case of Pigeon Breeder's disease, Farmer's lung, or humidifier fever...

Various types of implants are being commonly used for monitoring vital signals and controlling the critically ill patient's condition such as arrhythmia, sick sinus syndrome, etc. For implanting these medical devices under the skin, surgery is inevitable. These days many patients are more willing to accept interventional therapies that are less invasive, especially inserting a catheter into a blood vessel or endoscopy through a natural orifice. To be able to use interventional therapy for implanting medical devices, they will need to be small enough to fit them through a catheter or the forceps channel of an endoscope...

Bradyarrhythmia (bradycardia) is a heart rate lower than 60 beats/min. It can be due to sinus, atrial, or junctional bradycardia or to a problem with the conduction system (eg, an atrioventricular block). Asymptomatic bradycardia is common, especially among trained athletes or during sleep. Bradycardia symptoms can include syncope, dizziness, chest pain, dyspnea, or fatigue. It is important to determine during the evaluation if bradycardia is the cause of the patient's symptoms. In the acute setting, symptomatic patients should be treated with atropine...

BACKGROUND: Atrioventricular block (AVB) is common after transcatheter aortic valve replacement (TAVR) and permanent pacemaker (PPM) implantation is needed in up to 30% of patients. Main predictors of long term AVB are electrocardiographic. The purpose of this study is to assess the prognostic value of serial HV intervals measured before and after TAVR to shorten the timing of PPM implantation. METHODS: His bundle recordings were performed before (HV1), immediately after TAVR (HV2) and at day 2 for Edwards Sapien (ES) and 5 for Medtronic CoreValve (CV) (HV3)...

BACKGROUND: Phenotypes often differ even within family members carrying the same SCN5A mutation. We aimed to evaluate the genetic modifiers in a family with Brugada syndrome (BrS) and sick sinus syndrome (SSS) with an SCN5A mutation that causes the truncated alpha-subunit of cardiac Na channel protein. METHODS: To detect the genetic modifiers, we performed targeted panel sequencing of the coding region of 46 genes that are related to primary arrhythmia syndrome, by using a bench-top, next generation sequencer...
