an electrocardiogram (ecg) leads physicians to diagnose many potentially life-threatening cardiac, metabolic, electrolyte, and toxicological conditions. this study was designed to evaluate the competency of emergency medicine residents (emrs) in comparison with cardiologists in the interpretation of ecg when an interpretation checklist is used. this clinical trial was done in the emergency ward...

abstract background: brugada syndrome (bs) is an inherited ion channelopathy characterized by an electrocardiographic (ecg) pattern of a coved type st segment elevation in right precordial leads with or without right bundle branch block. case presentation: a 23-year old male presented with right lower quadrant abdominal pain. further evaluation revealed a diagnosis of acute appendicitis. the pa...

BACKGROUND Limited data are available on the effects of a ketogenic diet on dispersion duration of P-wave and QT-interval measures in children. We searched for the changes in these measures with serial electrocardiograms in patients treated with a ketogenic diet. METHODS Twenty-five drug-resistant patients with epilepsy treated with a ketogenic diet were enrolled in this study. Electrocardiog...

Chest surface motion is of significant importance as it contains information of respiratory and cardiac systems together with the complex coupling between these two systems. Chest surface motion is not only critical in radiotherapy, but also useful in personalized systems for continuous cardiorespiratory monitoring. In this dataset, a multimodal setup is employed to simultaneously acquire cardi...

A 20-dipole digital computer model of the electromotive surface generated by the heart with a simulated human male torso, including lungs, is presented. The simulated torso-surface ECG equipotential maps were compared to those seen in normal human subjects by Taccardi and were found to resemble them to within the resolution of these maps throughout most of ventricular depolarization (QRS). On c...
