Causal Relationship Between Electrocardiogram Parameters and Brugada Syndrome: A Bidirectional Mendelian Randomization Study. [PDF]

Ann Noninvasive Electrocardiol
This study uses Mendelian randomization to show that electrocardiogram parameters, including ST duration and QRS duration, have a causal effect on Brugada syndrome, offering new insights for understanding and managing the condition in clinical settings.

Risk stratification of elderly patients with Brugada syndrome: Results from a large Japanese cohort of idiopathic ventricular fibrillation. [PDF]

J Arrhythm
This study suggests that asymptomatic elderly patients with Brugada syndrome may be at a very low risk of developing life‐threatening arrhythmias. Abstract Background Brugada syndrome (BrS) is an inherited cardiac channelopathy associated with a high risk of sudden cardiac death (SCD) due to ventricular fibrillation (VF).

Soft, stretchable, wireless intelligent three‐lead electrocardiograph monitors with feedback functions for warning of potential heart attack

SmartMat, Volume 3, Issue 4, Page 668-684, December 2022., 2022
In this manuscript, we developed a stretchable, three‐lead electrocardiography (ECG) device based on self‐developed organohydrogel patches with strong adhesion and high conductivity for continuously monitoring human ECG signals. A safety warning system based on a mechanical vibration actuator is built up inside the ECG device as an indicator of the ...

Models of the cardiac L‐type calcium current: A quantitative review

WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023
We discuss 73 published models of mammalian ICaL and find differences in gating kinetics, electrochemical driving force, and sensitivity to internal calcium concentrations, leading to considerable variability in their predictions. Abstract The L‐type calcium current (ICaL) plays a critical role in cardiac electrophysiology, and models of ICaL are vital

Syncope with QT‐interval prolongation and T‐wave inversion in anterior and inferior leads: Foreboder of a life‐threatening condition?

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The patient’s ECG exhibited QT‐interval prolongation with T‐wave inversion in anterior and inferior leads that, together with CT‐pulmonary angiography findings, strongly suggested PE. This ECG pattern is crucial for diagnosing PE. Abstract Even though patients with pulmonary embolism usually present with respiratory distress and tachycardia, the ...

Microvolt T‐wave alternans in early repolarization syndrome associated with ventricular arrhythmias: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.

The diagnostic role of T wave morphology biomarkers in congenital and acquired long QT syndrome: A systematic review

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Numerous T wave morphology biomarkers, which can supplement QTc assessment in long QT syndrome (LQTS), have been identified. Their diagnostic capabilities include differentiation of genotypes, identification of concealed LQTS, differentiating acquired LQTS from congenital LQTS; and determining multichannel versus hERG channel blockade.

High‐resolution in vivo monophasic gastric slow waves to quantify activation and recovery profiles

Neurogastroenterology &Motility, Volume 34, Issue 12, December 2022., 2022
A novel high‐resolution multi‐channel suction electrode array was developed and applied in vivo to record monophasic gastric slow waves. Spatiotemporal slow wave recovery phase analysis was more reliably performed on monophasic signals compared with the biphasic signals, owing to the defined recovery morphology.

Treatment of Electrical Storm with Amiodarone in Brugada Syndrome- an Unexpected Protective Effect [PDF]

, 2013
We are reporting on a 53 year old man with proven Brugada syndrome and ICD implantation for resuscitation in context of polymorphic VT. After recurrent arrhythmia he was treated with Amiodarone.
