Abstract Introduction The majority of idiopathic ventricular arrythmias arise from the right outflow tract (RVOT) and they represent nearly 10% all tachycardia (VT) admissions. It is paramount to precisely predict origin RVOT arrhythmias define appropriate approach before ablation procedure. Conventional 12-lead electrocardiogram (ECG) a useful tool for analysing cardiac arrhythmias, numerous E...

Background: Valvular heart disease presents a unique set of conditions during pregnancy and delivery with the potential adverse outcomes complicated by prior interventions anticoagulation. The aim this study was to describe profile obstetric valvular patients who delivered via caesarean section at Charlotte Maxeke Johannesburg Academic Hospital. Methods: A retrospective done using patient recor...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Mitral annulus disjunction (MAD) has been proposed as a contributing factor for arrythmias and mitral regurgitation in patients with valve prolapse (MVP), however its clinical relevance is still under investigation. Objective To evaluate the frequency MAD MVP patients, to characterize clinically assess potential marke...

Abstract Background Several autopsy and observational studies have investigated the link between mitral valve prolapse (MVP) sudden cardiac death (SCD) due to well accepted yet rare occurrence of complex ventricular arrhythmia (VA) in this cohort. Few however whether burden more importantly SCD are reduced following surgical correction MVP. Purpose To investigate impact surgery (MVS) (replaceme...

Objective: The optimal time and approach of repair of tetralogy of Fallot (TOF) remain controversial. The purpose of this study was to evaluate the outcome following repair of TOF in infants with particular regard to the surgical approach used. Patients: One hundred and sixty infants (mean age 195 ^ 89 days, range 11–364 days) undergoing repair of a simple TOF were studied. Between 1974 and 200...

Abstract Introduction Long QT Syndrome (LQTS) is a rare cardiac channelopathy characterized by high risk of lethal arrhythmias. Pregnancy and post–partum period may induce an increased vulnerability, so appropriate prevention needed. Case presentation A 31–year–old primigravid woman at 36 weeks pregnancy was referred to our Cardiomyopathy Unit located in tertiary centre for LQTS screening. The ...

Objectives: Our study aimed to investigate the frequency of malignant cardiac arrhythmias in hospitalized patients receiving hydroxychloroquine alone and those a combination with azithromycin, as well quantitative extent QT prolongation within Tisdale Risk Score (TRS) categories. Background: There have been over 33 million cases SARS-CoV-2 (COVID-19) resulting 600,000 deaths United States. As c...

BACKGROUND Electrocardiographic methods still provide the bulk of cardiovascular diagnostics. Cardiac ischemia is associated with typical alterations in cardiac biosignals that have to be measured, analyzed by mathematical algorithms and allegorized for further clinical diagnostics. The fast growing fields of biomedical engineering and applied sciences are intensely focused on generating new ap...

Abstract Background Radiation therapy (RT) is widely diffused in the treatment of cancer; but it could lead to various negative consequences on cardiovascular system, even several years after end. They include also valvular heart diseases, arrythmias, coronary artery failure, pericardial systemic and pulmonary diseases. We report an interesting case about RT cardiotoxicity different manifestati...
