Wandering Bundles With Sinus Arrhythmia

JACC: Case Reports, 2023
A 3-year-old boy with congenital ventricular septal defect underwent a closure procedure. Telemetry after the procedure reveals sinus arrhythmia with varying types of bundle branch blocks. Inverse decremental conduction in left posterior fascicle, related to preceding RP interval during sinus arrhythmia, underlies changes between right and left bundle ...

Sick sinus syndrome diagnosed after a sinus arrest during treatment for zygomatic fracture: a case report

BMC Oral Health, 2023
Background Intraoperative sinus arrest is rarely seen during zygomatic fracture treatment. The patient was diagnosed with sick sinus syndrome based on repeated postoperative sinus arrest, which could have resulted in death if diagnosed late, making this ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Adapting detection sensitivity based on evidence of irregular sinus arrhythmia to improve atrial fibrillation detection in insertable cardiac monitors

Europace, 2017
Aims Intermittent change in p-wave discernibility during periods of ectopy and sinus arrhythmia is a cause of inappropriate atrial fibrillation (AF) detection in insertable cardiac monitors (ICM).

Reduced vagal tone in women with the FMR1 premutation is associated with FMR1 mRNA but not depression or anxiety

Journal of Neurodevelopmental Disorders, 2017
Background Autonomic dysfunction is implicated in a range of psychological conditions, including depression and anxiety. The fragile X mental retardation-1 (FMR1) premutation is a common genetic mutation that affects ~1:150 women and is associated with ...

In vivo dose measurement using TLDs and MOSFET dosimeters for cardiac radiosurgery. [PDF]

, 2012
In vivo measurements were made of the dose delivered to animal models in an effort to develop a method for treating cardiac arrhythmia using radiation. This treatment would replace RF energy (currently used to create cardiac scar) with ionizing radiation.

Brainstem sources of cardiac vagal tone and respiratory sinus arrhythmia

Journal of Physiology, 2016
Cardiac vagal tone is a strong predictor of health, although its central origins are unknown. Respiratory‐linked fluctuations in cardiac vagal tone give rise to respiratory sinus arryhthmia (RSA), with maximum tone in the post‐inspiratory phase of ...

Severe congenital RYR1-associated myopathy complicated with atrial tachycardia and sinus node dysfunction: a case report

Italian Journal of Pediatrics, 2019
Background Cardiac arrhythmias are sometimes encountered in patients with hereditary myopathies and muscular dystrophies. Description of arrhythmias in myopathies and muscular dystrophies is very important, because arrhythmias have a strong impact on the

Electrocardiographic patch devices and contemporary wireless cardiac monitoring. [PDF]

, 2015
Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes.
