Serial 3 orthogonal lead electrocardiograms were recorded on 67 patients with acute myocardial infarction. For each series of electrocardiograms, the day to day changes and the changes with respect to the initial computer measurements of selected ST-T segment amplitudes and vector orientations were investigated. The results indicated that the degree of rotation of ST-T vectors, which correspond...

Introduction: A large number of electrocardiograms (ECG) are shared on Twitter every day. Some them aim to provide information the readers, and some training with a mini quiz. This study aimed discuss evaluability ECG images Twitter. Methods: The sample consisted 12-lead 08/01/2020 - 01/31/2021 were manually scanned. Results: total 286 tweets matching criteria included in specified dates. major...

A stepwise analytic approach is needed to decipher tachyarrhythmia electrocardiograms. It also important be able promptly recognize certain characteristic patterns described in some classical arrhythmias. Knowledge of these unique electrocardiogram morphologies and the underlying reasons for them help quick diagnosis appropriate management.

Electrocardiography is a useful tool in the management of paediatric heart disease. Interpretation requires practice due to changing norms which are brought about by the physiological changes that occur in the circulatory system in this age group. This article outlines these normal changes.

We present preliminary results of the numerical simulation of electrocardiograms (ECG). We consider the bidomain equations to model the electrical activity of the heart and a Laplace equation for the torso. The ionic activity is modeled with a Mitchell-Schaeffer dynamics. We use adaptive semi-implicit BDF schemes for the time discretization and a Neumann-Robin domain decomposition algorithm for...

BACKGROUND Detection of QRS complexes and other types of ventricular beats is a basic component of ECG analysis. Many algorithms have been proposed and used because of the waves' shape diversity. Detection in a single channel ECG is important for several applications, such as in defibrillators and specialized monitors. METHODS The developed heuristic algorithm for ventricular beat detection i...

Between August 1954 and May 1957, 682 R.A.F. officers and men volunteered for a study of the electrocardiogram after exercise. Of these, 660 were selected because they had no symptoms, no clinical or radiological evidence of heart disease, a diastolic blood pressure of below 100 mm. Hg, and a normal 12-lead electrocardiogram taken at rest. Certain minor electrocardiographic changes that are bel...
