The relationship between repolarisation alternans and the production of ventricular arrhythmia in heart failure
… alternans is thought to predict the risk of ventricular arrhythmias in patients with heart disease, although recent clinical studies have conflicting results. Understanding the cellular basis for alternans may not only inform more effective utilisation of the clinical test, but also provide …

Optimal Analytical Methods for High Accuracy Cardiac Disease Classification and Treatment Based on ECG Data
… community in conducting new studies on arrhythmia and other cardiovascular conditions. In the second project, we created a new 12-lead ECG database under the auspices of Chapman University and Ningbo First Hospital of Zhejiang University that aims to provide high quality data enabling …

The Pattern of Ventricular Repolarization during Therapeutic Hypothermia
… (QTc). QTc prolongation can cause polymorphic ventricular tachycardia (VT) and ventricular fibrillation (VF). The interval from the peak to the end of the T wave (TpTe) indicates myocardial transmural dispersion of repolarization (TDR) and increased TDR may create electrophysiological …

Cardiotoxicity In Hematologic Stem Cell Transplant: Keeping The Beat
… experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression …

Reductive metabolism of aliphatic tertiary amine n-oxides.
… of lignocaine and the drug of choice for ventricular arrhythmia, a symptom associated with ischaemic episodes leading to regions of transiently hypoxic heart tissue. An HPLC analytical method was developed to study the metabolism of lignocaine N-oxide. The rapid and sensitive analysis of …

Amelioration of oxidative lung injury by antiarrhythmic agents
… valuable for the treatment and prevention of ventricular arrhythmia occurring after surgical correction of myocardial infraction. We found that the class I antiarrhythmic drugs are effective in ameliorating post-ischemic lung reperfusion injury in an ex vivo perfused rat lung model exposed to …

Vectorcardiographic evaluation of ventricular repolarization in healthy individuals and LQTS mutation carriers
Ventricular arrhythmia is a well-known cause of syncopal attacks and sudden cardiac death in humans. Ventricular repolarization (VR) is the most unstable phase in cardiac electrical activity and its regulation depends on the coordinated activity in multiple ion channels. Several physiological …

Ventrikelteilresektion bei Adriamycin-induzierter Cardiomyopathie am Tiermodell
… adriamycin administration (probably due to ventricular arrhythmia). In addition, 1 dog from Group 2 suffered from a severe systemic inflammatory response syndrome after PLV and died 36 hours after surgery. Thus, 5 dogs from Group 1 and 4 from Group 2 undervent the entire study protocol. …

Model Based Analysis of QT Variability Independent of Heart Rate and Respiration
… predisposes patients to abnormal heart rhythms (ventricular arrhythmia) and sudden cardiac death (SCD). Current risk assessment strategies for identifying patients at high risk of SCD are mainly based on markers of structural dysfunction. However, most deaths occur in those deemed at low risk by …

Defining a Novel Role for the E3 Ubiquitin Ligase Wwp1 in Cardiac Arrhythmogenesis
… variety of heart pathologies that predispose to ventricular arrhythmogenesis (e.g., coronary artery disease, cardiomyopatheis, or channelopathies), therapies that prevent SCD would have a major impact in medical practice as there are few options that currently exist. In the heart, gap junctions …

Einfluß und Wirksamkeit von Propafenon auf ischämiebedingte EKG-Veränderungen und ventrikuläre Arrhythmien während akutem, iatrogen induziertem Koronarverschluß (PTCA) im Vergleich zu Placebo
Die koronare Herzerkrankung ist mit einem deutlich erhöhten Risiko für das Auftreten eines plötzlichen Herztodes verbunden. Verantwortlich sind meist maligne ventrikuläre Tachyarrhythmien, wobei der Interaktion einer myokardialen Ischämie und dem Auftreten der ventrikulären Arrhythmie eine …

Real Time Frequency Analysis of Signals From Lasso Catheter For Radiofrequency Ablation During Atrial Fibrillation
Real time spectrum analysis of signals obtained through lasso catheter during radiofrequency ablation of pulmonary vein was performed to determine the channel with dominant frequency. Threshold algorithm was used for signals which could be classified as type I and type II AF. Type III AF Signals …
