Hiroshi Morita, Koji Nakagawa, Akira Ueoka, Tomofumi Mizuno, more

Journal of Cardiovascular Electrophysiology > 35 > 2 > 307 - 316

Introduction Electrical storm (ES) of ventricular tachyarrhythmias (VTAs) is an important cause of sudden death in patients with cardiac sarcoidosis (CS). VTAs in CS are associated with myocardial scarring and inflammation. However, little is known about the risk factors of ES in patients with CS and VTAs. The objective of this study is to clarify the characteristics and risk factors for the development...

Lakkakula Kavya, Yepuganti Karuna, Saladi Saritha, Allam Jaya Prakash, more

International Journal of Applied Mathematics and Computer Science > 2024 > Vol. 34, no. 3 > 485--511

An electrocardiogram (ECG) is an essential medical tool for analyzing the functioning of the heart. An arrhythmia is a deviation in the shape of the ECG signal from the normal sinus rhythm. Long-term arrhythmias are the primary sources of cardiac disorders. Shockable arrhythmias, a type of life-threatening arrhythmia in cardiac patients, are characterized by disorganized or chaotic electrical activity...

Low‐energy defibrillation using a base–apex epicardial electrode

Jun‐ichi Okada, Takumi Washio, Seiryo Sugiura, Toshiaki Hisada

Pacing and Clinical Electrophysiology > 46 > 11 > 1325 - 1332

Background Current implantable cardioverter defibrillators (ICDs) require electric conduction with high voltage and high energy, which can impair cardiac function and induce another malignant arrhythmia. As a result, there has been a demand for an ICD that can effectively operate with lower energy to mitigate the risks of a strong electric shock. Methods A pair of sheet‐shaped electrodes covering...

Arrhythmias induced by dextrose‐insulin challenge test in nondiagnostic Brugada ECG patterns

Enrique Velázquez‐Rodríguez, José Paz Marcelo Jiménez‐Cruz

Journal of Cardiovascular Electrophysiology > 34 > 8 > 1776 - 1780

Introduction Dynamic ECG changes in Brugada syndrome (BrS) are influenced by several factors, may not be apparent, and can be unmasked by a drug test. Methods and Results Four of six patients with nondiagnostic Brugada ECG index patterns underwent a dextrose‐insulin challenge test that resulted in J‐ST segment elevation and triggered arrhythmias. Conclusion Insulin action may be due in part to...

Risk of ventricular arrhythmias following implantable cardioverter‐defibrillator generator change in patients with recovered ejection fraction: Implications for shared decision‐making

Donald D. Chang, Peter G. Pantlin, Francis A. Benn, T. Ryan Gullatt, more

Journal of Cardiovascular Electrophysiology > 34 > 6 > 1405 - 1414

Introduction Guidelines indicate primary‐prevention implantable cardioverter‐defibrillators (ICDs) for most patients with left ventricular ejection fraction (LVEF) ≤ 35%. Some patients' LVEFs improve during the life of their first ICD. In patients with recovered LVEF who never received appropriate ICD therapy, the utility of generator replacement upon battery depletion remains unclear. Here, we evaluate...

Delayed depolarization and histologic abnormalities underlie the Brugada syndrome

Bortolo Martini, Nicolò Martini, Luca De Mattia, Gianfranco Buja

Pacing and Clinical Electrophysiology > 46 > 2 > 172 - 181

Brugada syndrome (BrS) is a controversial disease whose pathophysiology is still far from being fully understood. Unlike other cardiological disorders, a definite etiology has not yet been established so that it could be summarized under two main chapters: “functional” or “organic”, “repolarization” or “depolarization” disorder. Despite initial descriptions leaned towards the organic substrate and...
