BACKGROUND: Ventricular tachycardia is a life threatening cardiac arrhythmia. It needs management with defibrillation, without which, immediate death may occur. CASE PRESENTATION: A 66 year old black African patient with a 2 year history of hypertension was admitted to the emergency department of the Buea Regional hospital, a semi-urban setting in Cameroon, after presenting with syncope while in church. The wife described a similar episode 2 weeks prior without any further evaluation...

During acute exacerbation of chronic obstructive pulmonary disease (AECOPD), myocardial stress may be aggravated. Sparse data exist concerning the prevalence and correlates of cardiac arrhythmias in the stable and exacerbated states of COPD. We hypothesized that AECOPD is associated with increased prevalence of cardiac arrhythmias independent of COPD-severity and co-morbidity, and explored possible mechanisms. A 24-hour Holter recording was obtained in 74 patients with stable COPD and 45 patients with AECOPD (mean age 54 years, 56% women)...

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a primary cardiomyopathy characterised by fibrofatty replacement and ventricular arrhythmias. The occurrence of malignant arrhythmias may be associated with fatty infiltration and intercalated disk remodelling, but the specific pathological remodelling pattern is not yet clear. METHODS: Twelve explanted hearts from patients diagnosed with ARVC/D according to the 2010 Task Force Criteria and pathology examination were divided into two groups with (SVT, n=6) or without (non-SVT, n=6) recurrent sustained ventricular tachycardia (SVT) before heart transplantation...

A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor. Cardiac magnetic resonance delayed gadolinium imaging revealed a region of patchy mid-myocardial enhancement within the left ventricular basal inferolateral myocardium. An 18-fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased uptake in the same area, consistent with active sarcoid, with no septal involvement...

Background: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease...
