Electrocardiographic J waves as a hyperacute sign of Takotsubo syndrome
14 May 2012
Alessandro Zorzi, Federico Migliore, Martina Perazzolo Marra, Giuseppe Tarantini, Sabino Iliceto, Domenico Corrado
Abstract: Typical electrocardiographic (ECG) signs of acute Takotsubo syndrome (TTS) consist of ST-segment elevation and/or T wave inversion. We report an unusual case of a 62-year-old woman with TTS ...

Prevalence of acute myocardial infarction in patients with presumably new left bundle-branch block
10 May 2012
Nilay Mehta, Henry D. Huang, Salman Bandeali, James M. Wilson, Yochai Birnbaum
Abstract: Objectives: We assessed the prevalence of true acute myocardial infarction and the need for emergent revascularization among patients with new or presumably new left bundle branch block (nLB...

Prevalence and clinical correlates of early repolarization and J wave in a large cohort of subjects without overt heart disease
10 May 2012
Gaetano A. Lanza, Roberto Mollo, Alessandro Cosenza, Gaetano Pinnacchio, Giulia Careri, Marianna Laurito, Filippo Crea
Abstract: Background: Recent studies have suggested that early repolarization (ER) is associated with increased risk of ventricular tachyarrhythmias. Early repolarization in these studies, however, wa...

T-wave morphology after epinephrine bolus may reveal silent long QT syndrome mutation carriers
07 May 2012
Anna-Mari Hekkala, Väänänen Heikki, Swan Heikki, Viitasalo Matti, Toivonen Lauri
Abstract: Background: Long QT syndrome (LQTS) gene mutation carriers with indeterminate electrocardiogram frequently escape clinical diagnosis. We assessed the use of epinephrine bolus injection in re...

The electrocardiographic diagnosis of intraventricular blocks coexisting with ventricular preexcitation
07 May 2012
Pablo A. Chiale, Marcelo V. Elizari
Abstract: The electrocardiographic diagnosis of intraventricular conduction disturbances may be hindered by the coexistence of ventricular preexcitation. In fact, the premature depolarization of ventr...
