Dec 31st, 2022 - To characterize ventricular bigeminy from 24-h Holter recordings of Andersen-Tawil syndrome (ATS) patients, a first comparison with a large database of post-myocardial infarction (post-MI) patients with frequent premature ventricular complexes (PV...

Jun 15th, 2022 - Bidirectional ventricular tachycardia (BiVT) is a rare form of ventricular tachycardia that manifests on surface electrocardiogram by dual QRS morphologies alternating on a beat-to-beat basis. It was first reported in the 1920s as a complication o...

May 17th, 2022 - Congenital Long QT Syndrome (CLQTS) is the most common inherited arrhythmia. The QT interval, which marks the duration of ventricular depolarization and repolarization in the myocardium, can be prolonged due to mutations in genes coding for the io...

Apr 24th, 2022 - Andersen-Tawil syndrome (ATS) is a skeletal muscle channelopathy caused by KCNJ2 mutations, characterized by a clinical triad of periodic paralysis, cardiac arrhythmias and dysmorphism. The muscle phenotype, particularly the atypical forms with pr...

Apr 17th, 2022 - Andersen-Tawil syndrome is a rare autosomal dominant genetic or sporadic disorder characterized by periodic paralysis, ventricular arrhythmias and dysmorphic features. Ventricular arrhythmias can include frequent premature ventricular complex, pol...

Jan 16th, 2013 - ATS is an ion channel disorder that causes episodes of muscle weakness and potentially life-threatening heart arrhythmias for which no treatment has been identified. The majority of ATS cases are caused by a mutation in the KCNJ2 gene; other cases...

Jan 20th, 2012 - ATS is an ion channel disorder that causes episodes of muscle weakness and potentially life-threatening heart arrhythmias. The majority of ATS cases are caused by a mutation in the KCNJ2 gene, which is linked to potassium channels in the heart, br...

Oct 29th, 2018 - Like many rare disorders, periodic paralysis can go undiagnosed and be easily misinterpreted as a wide variety of neurologic or other disorders. But with increased awareness of the unique symptoms of this disorder and how to manage them, patients ...
