U Wave: Facts, Hypotheses, Misconceptions, and MisnomersJournal of Cardiovascular Electrophysiology - Tập 9 Số 10 - Trang 1117-1128 - 1998

U Wave. The clinical significance of U wave is limited to the occasional obfuscation of the end of T wave and an inadequately explained U wave inversion associated with myocardial ischemia, infarction, and ventricular hypertrophy and dilatation. Lengthening of QT interval often interferes with the recognition of U wave. The characteristics of U wave are not compatible with the Purkinje or ...... hiện toàn bộ
Calcium Cycling in Heart Failure: The Arrhythmia ConnectionJournal of Cardiovascular Electrophysiology - Tập 13 Số 1 - Trang 88-91 - 2002
Steven M. Pogwizd, Donald M. Bers
Calcium Cycling in Heart Failure. Ventricular tachycardia in nonischemic heart failure (HF) arises from a nonreentrant mechanism most likely due to delayed afterdepolarizations from activation of a transient inward current (Iti). We present data and a paradigm in which an up‐regulated Na/Ca exchanger, residual‐adrenergic responsiveness, and decr...... hiện toàn bộ
Conduction Properties of the Inferior Vena Cava‐Tricuspid Annular Isthmus in Patients with Typical Atrial FlutterJournal of Cardiovascular Electrophysiology - Tập 8 Số 7 - Trang 727-737 - 1997

Conduction Properties of the Annular Isthmus. Introduction: A functional region of slow conduction located in the inferior right atrium has been postulated to be critical to the induction and maintenance of typical human atrial flutter. We reexamined the potential role of functional conduction delay in the annular isthmus between the tricuspid valve and the infer...... hiện toàn bộ
Long‐Term Outcome of Radiofrequency Catheter Ablation for Topical Atrial Flutter: Risk Prediction of Recurrent ArrhythmiasJournal of Cardiovascular Electrophysiology - Tập 9 Số 2 - Trang 115-121 - 1998

RF Catheter Ablation for Atrial Flutter. Introduction: Little is known about the predictors of recurrent atrial flutter or fibrillation after successful radiofrequency ablation of typical atrial flutter. In addition, there is only limited evidence suggesting that elimination of atrial flutter would modify the natural history of atrial fibrillation in patients who...... hiện toàn bộ
