The Hidden Rhythm: A Rare Case of Isoarrhythmic Sick Sinus Syndrome Defying Chronotropic Expectations

International Journal of Medical Students
Background: Isoarrhythmic sick sinus syndrome (SSS) is a rare and often under-recognized variant of sinus node dysfunction, where the sinus and junctional rates are nearly identical, masquerading as a normal rhythm.

Permanent pacemaker implantation in unexplained syncope patients with borderline sinus bradycardia and electrophysiology study‐proven sinus node disease

Journal of Arrhythmia, 2021
Background Significant sinus bradycardia (SB) in the context of sinus node dysfunction (SND) has been associated with neurological symptoms. The objective was to evaluate the effect of permanent pacing on the incidence of syncope in patients with rather ...

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency

Epilepsia, EarlyView.
Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Generation of a patient-specific hiPS cell line with heterozygous GNB2 mutation (UKMi003-A) causative for human sinus node dysfunction and a corresponding CRISPR/Cas9-corrected isogenic control (UKMi004-A)

Stem Cell Research
The heterozygous mutation c.155G > T in GNB2 clinically leads to sinus bradycardia and sinus node dysfunction. Here, patient-specific skin fibroblasts of the mutation carrier were used for Sendai virus reprogramming into human induced-pluripotent stem ...

The measurement of sinus node refractoriness in man.

, 1983
We recently described a method for measuring sinus node refractoriness in the rabbit heart. Atrial premature beats either may result in reset return responses or may become interpolated because of encroachment on sinus node refractoriness.

SINUS NODE DYSFUNCTION IN CHILDREN [PDF]

Pediatric Research, 1977
Over a three year period, 30 pedlatric patients (pts) with electrocardiographic evidence of sinus node dysfunction (SND) were identified. Their ages ranged from 3 days to 21 years. Twenty-two pts had significant heart disease. In 13, the onset of SND followed corrective cardiac surgery, and of these, 8 were operations for atrial septal defect and ...

Intraoperative Indocyanine Green Fluorescence Enables Primary Tumor Localization and Treatment De‐Escalation in SCCUP: A Case Report

Head &Neck, EarlyView.
ABSTRACT Background Unknown primary cancer in the head and neck presents a difficult surgical treatment dilemma. Patients with squamous cell carcinoma of unknown primary (SCCUP) typically present with an enlarging neck mass found on biopsy but with no indication of primary site on diagnostic exams such as flexible laryngoscopy, CT, MRI, and/or PET/CT ...

Sinus node dysfunction after repair of partial anomalous pulmonary venous connection

, 2008
ObjectivesSinus node dysfunction is known as a major complication after repair of partial anomalous pulmonary venous connection. We retrospectively analyzed the results of the atrial wall flap technique compared with the results of patch repair or direct

Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control
