Myocardial repolarization is affected in patients with ascending aortic aneurysm
Ascending aortic aneurysm (AAA) is one of the major causes of ventricular diastolic dysfunction. Diastolic dysfunction can induce ventricular repolarization dispersion. Nevertheless, myocardial repolarization dispersion is not yet to be fully evaluated in patients with AAA. We aimed to evaluate ventricular repolarization using QT and Tp-Te interval and corrected (c) Tp-Te/QT ratio in patients with AAA. (Source: Journal of Electrocardiology)

Evaluation of ventricular repolarization features with Tp-e, Tp-e/QTc, JTc and JTd during electroconvulsive therapy
The purpose of this study was to investigate the influence of electrical stimulation transmitted through the body during electroconvulsive therapy on traditional and relatively new ventricular repolarization parameters (Rate corrected QT interval (QTc), QT dispersion (QTd), rate corrected JT interval (JTc), JT dispersion (JTd), T-peak to T-end interval (Tp-e) and Tp-e/QTc ratio) under propofol anaesthesia.

The association between reconstructed phase space and Artificial Neural Networks for vectorcardiographic recognition of myocardial infarction
Myocardial infarction is one of the leading causes of death worldwide. As it is life threatening, it requires an immediate and precise treatment. Due to this, a growing number of research and innovations in the field of biomedical signal processing is in high demand. This paper proposes the association of Reconstructed Phase Space and Artificial Neural Networks for Vectorcardiography Myocardial Infarction Recognition. The algorithm promotes better results for the box size 10 × 10 and the combination of four parameters: box counting (Vx), box counting (Vz), self-similarity method (Vx) and self-similarity method (Vy) w...

Late restored cardiac function after successful resynchronization by right posterior accessory pathway ablation in Wolff –Parkinson–White syndrome associated dilated cardiomyopathy
Wolff-Parkinson-White (WPW) syndrome is one of the most common arrhythmias in children. Supraventricular tachycardia (SVT) is a common clinical manifestation and may present as palpitation and near syncope. In addition, patients with overt ventricular preexcitation are also at risk for developing dilated cardiomyopathy (DCM), which may be caused by either incessant tachyarrhythmia or accessory pathway (AP) related dyssynchronization [1 –4]. Cardiac function can improve after elimination of AP [5–8]. (Source: Journal of Electrocardiology)

Bradycardia: What is the mechanism?
A 70-year old female with history of diabetes, hypertension, hyperlipidemia and depression was admitted to our hospital with nausea and upper abdominal pain. Her symptoms initially started 2 months prior to this presentation when she was vacationing in Italy. She described a vague upper abdominal rash that resolved, but she continued to have sharp pain intermittently which wrapped around her abdomen. She was diagnosed to have possible shingles as an outpatient and was symptomatically managed with tramadol and gabapentin. (Source: Journal of Electrocardiology)

Author's re`sponse to letter to the editor from Hay ırlıoğlu M et al.
We have read with great interest the letter entitled “How can we find out the perfect admission electrocardiographic parameter to predict no-reflow?” authored by Hayırlıoğlu M et al. We would like to submit a response letter regarding their valuable and constructive criticisms. Firstly; the authors have pointed that level of electrolytes on adm ission particularly potassium could affect atrial conduction properties and its electrocardiographics reflection such as p wave duration, amplitude and p wave peak time.

Alternans during fascicular ventricular tachycardia due to digitalis toxicity
This report describes a digitalis-induced regular fascicular ventricular tachycardia characterized by marked QRS alternans a manifestation not usually associated with this arrhythmia. The striking alternation of QRS configuration suggested alternating ventricular activation from either a single focus with two exits in distal branches of the left anterior fascicle or 2 different foci localized in the Purkinje-myocardial network of the left anterior fascicle.
