Electrocardiography deals with the electrical activity of the heart. The condition of cardiac health is given by ECG and heart rate. A study of the nonlinear dynamics of electrocardiogram (ECG) signals for arrhythmia characterization is considered. The statistical analysis of the calculated features indicate that they differ significantly between normal heart rhythm and the different arrhythmia...
the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...
Cardiac symptoms and premature death from cardiac causes are still major problem with beta thalassemia despite chelation therapy. Heart complications are the leading causes of mortality in the absence of effective iron chelation therapy. Many patients develop evidence of iron-induced myocardial damage with cardiac failure, cardiac arrhythmia, sudden death or death from progressive conge...
Catecholaminergic polymorphic ventricular tachycardia is a rare cause of exercise-induced arrhythmia and sudden cardiac death in the pediatric patient. This arrhythmia is difficult to diagnose in the emergency department, given the range of presentations; thus, a familiarity with and high index of suspicion for this pathology are crucial. Furthermore, recognition of the characteristic electroca...
An Electrocardiogram (ECG) graphically records changes in electrical potentials between different sites on the skin due to cardiac activity. The heart’s electrical activity is a depolarization and depolarization sequence. ECGs help in identifying cardiac arrhythmia because they have diagnostic information. ECG arrhythmia detection accuracy improves by using machine learning and data mining meth...
We reported a case of a 72-year-old male, known diabetic on insulin, referred because of complete atrioventricular block. He was found to have acute hepatitis during which he developed transient atrial arrhythmia, and sinus node dysfunction. His cardiac symptoms disappeared completely after hepatitis improvement. All of his cardiac investigations were normal including electrocardiogram, echocar...
Calcium/calmodulin-dependent protein kinase II (CaMKII) activity has been shown to contribute to arrhythmogenesis in a remarkably broad range of cardiac pathologies. Several of these involve significant structural and electrophysiologic remodeling, whereas others are due to specific channelopathies, and are not typically associated with arrhythmogenic changes to protein expression or cellular a...
Filamin C (FLNC) gene variants have been reported to be associated with arrhythmogenic cardiomyopathy (ACM), dilated (DCM), and sudden cardiac death. Currently left ejection fraction death risks do not appear clearly associated. FLNC DSP + tend show ring-shaped sub-epicardial scars. Although there is evidence suggest can cause arrhythmia or arrest, it continues as a variant of uncertain signifi...
Background: Atrial fibrillation is the most common but benign arrhythmia following cardiac surgery. Although this arrhythmia is often self-limited and vanishes in about 24 hours upon surgery a number of arrhythmias might ensue among which some might be really life-threatening. A multitude of therapeutic modalities have been proposed for the prevention of this arrhythmia and one of them is poste...
The Brugada syndrome (BrS) is a rare heritable cardiac arrhythmia disorder associated with ventricular fibrillation and sudden cardiac death. Mutations in the SCN5A gene have been causally related to BrS in 20-30% of cases. Twenty other genes have been described as involved in BrS, but their overall contribution to disease prevalence is still unclear. This study aims to estimate the burden of r...
