Ventricular fibrillation (VF) is a life-threatening arrhythmia and a common cause of sudden cardiac death (SCD). A basic understanding of its mechanistic underpinning is crucial for enhancing our knowledge to develop innovative mapping and ablation techniques for this lethal rhythm. Significant advances in our understanding of VF have been made especially in the basic science and pre-clinical expe...... hiện toàn bộ

The purpose of this study is to analyze the relationship between contact force (CF) and pacing threshold in left atrium (LA). Six to ten LA sites were studied in 28 consecutive patients with atrial fibrillation undergoing pulmonary vein isolation. Median CF, bipolar and unipolar electrogram voltage, impedance, and bipolar and unipolar thresholds for consistent constant capture and for consistent i...... hiện toàn bộ

The study sought to assess retrospectively the prognostic impact of left ventricular ejection fraction (LVEF) in patients with electrical storm (ES). Data regarding the prognostic impact of impaired LVEF in ES patients is rare. Consecutive patients presenting with ES from 2002 to 2016 were included retrospectively. Patients with LVEF ≤ 35% were compared to patients with LVEF > 35%. The primary pro...... hiện toàn bộ
Remote-controlled magnetic ablation of a right anterolateral accessory pathway—The superior caval vein approachSpringer Science and Business Media LLC - - 2006
Julian Kyoung-Ryul Chun, Boris Schmidt, Karl-Heinz Kuck, Sabine Ernst
An 18-year old male patient with recurrent supraventricular tachycardias was admitted for catheter ablation. Baseline ECG was consistent with right anterolateral accessory pathway (AP) conduction. The novel magnetic navigation system (MNS, Niobe Stereotaxis) in combination with a catheter advancer unit (Cardiodrive, Stereotaxis) allows a complete remote-controlled electrophysiologic study and abla...... hiện toàn bộ
A contemporary view of atrioventricular nodal physiologySpringer Science and Business Media LLC - Tập 52 - Trang 271-279 - 2018
Steven M. Markowitz, Bruce B. Lerman
In delaying transmission of the cardiac impulse from the atria to the ventricles, the atrioventricular (AV) node serves a critical function in augmenting ventricular filling during diastole and limiting the ventricular response during atrial tachyarrhythmias. The complex structure of the nodal region, however, also provides the substrate for reentrant rhythms. Recent discoveries have elucidated th...... hiện toàn bộ
