Comparison of cardiovascular magnetic resonance characteristics and clinical prognosis in left ventricular noncompaction patients with and without arrhythmia

BMC Cardiovascular Disorders, 2022
Background Left ventricular noncompaction (LVNC) is a rare type of cardiomyopathy, and one of its clinical manifestations is arrhythmia. Cardiovascular magnetic resonance (CMR) is valuable for the diagnosis and prognosis of LVNC.

Cardiac dopamine D1 receptor triggers ventricular arrhythmia in chronic heart failure

Nature Communications, 2020
Pathophysiological roles of cardiac dopamine system remain unknown. Here, we show the role of dopamine D1 receptor (D1R)-expressing cardiomyocytes (CMs) in triggering heart failure-associated ventricular arrhythmia.

Ventricular arrhythmia burden during the coronavirus disease 2019 (COVID-19) pandemic

European Heart Journal, 2020
Aims Our objective was to determine the ventricular arrhythmia burden in implantable cardioverter-defibrillator (ICD) patients during COVID-19. Methods and results In this multicentre, observational, cohort study over a 100-day period during the COVID-19

A 12-Lead ECG database to identify origins of idiopathic ventricular arrhythmia containing 334 patients

Scientific Data, 2020
Cardiac catheter ablation has shown the effectiveness of treating the idiopathic premature ventricular complex and ventricular tachycardia. As the most important prerequisite for successful therapy, criteria based on analysis of 12-lead ECGs are employed

Short‐Term Variability of the QT Interval Can be Used for the Prediction of Imminent Ventricular Arrhythmias in Patients With Primary Prophylactic Implantable Cardioverter Defibrillators

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Short‐term variability of the QT interval (STVQT) has been proposed as a novel electrophysiological marker for the prediction of imminent ventricular arrhythmias in animal models.

Physical exercise and arrhythmogenic right ventricular cardiomyopathy/dysplasia: An overview

Heart Views, 2022
Arrhythmogenic right ventricular cardiomyopathy/dysplasia is inherited cardiomyopathy that has a propensity for ventricular arrhythmia, ventricular dysfunction, and sudden cardiac death.

Long-term nifekalant use in a patient with dilated cardiomyopathy and recurrent ventricular tachycardia

Journal of International Medical Research, 2022
The potential utility of nifekalant, a new Class III antiarrhythmic drug, to offer long-term protection against ventricular arrhythmia has been investigated in this case report.

The Genetics and Epigenetics of Ventricular Arrhythmias in Patients Without Structural Heart Disease

Frontiers in Cardiovascular Medicine, 2022
Ventricular arrhythmia without structural heart disease is an arrhythmic disorder that occurs in structurally normal heart and no transient or reversible arrhythmia factors, such as electrolyte disorders and myocardial ischemia.

The self-maintaining nature of ventricular fibrillation : contribution of L-type Ca²+ channels and Na+/Ca²+ exchange to cardiomyocyte Ca²+ overload in ventricular fibrillation : surface fluorescence study in isolated perfused rat hearts [PDF]

, 2004
Approximately 40% of all deaths in Switzerland are due to cardiovascular diseases.1 An important part of these deaths happen because of life-threatening cardiac arrhythmias.
