Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting more than three million Americans.1 The management of AF revolves around the alleviation of symptoms related to an accelerated and irregular ventricular response, and the prevention of cardioembolism, notably stroke. In patients with AF, there is a fivefold increased incidence of embolic stroke.2 The prevention of systemic… View more

Optimal cardiac function depends on appropriate rate and force of contraction, with specific cardiac regions having developed particular beat-to-beat properties depending on their individual functions. For example, isovolumetric contraction time is shorter in the right ventricle (RV) than in the left ventricle (LV). At the cellular level, cardiac function is regulated by regional cardiomyocyte… View more

Differential Diagnosis of Wide QRS Tachycardias
Author(s): Demosthenes G Katritsis , Josep Brugada Added: 3 years ago
The term narrow QRS tachycardia indicates individuals with a QRS duration ≤120 ms, while wide QRS tachycardia refers to tachycardia with a QRS duration >120 ms.1 Narrow QRS complexes are due to rapid activation of the ventricles via the His–Purkinje system, suggesting that the origin of the arrhythmia is above or within the His bundle. However, early activation of the His bundle can also occur… View more

EHRA 23: AdaptResponse: AdaptivCRT® Algorithm in Synchronized LV Pacing
Author(s): Bruce Wilkoff Added: 1 year ago
EHRA 23– Dr Bruce Wilkoff (Cleveland Clinic, US) joins us on-site to outline the findings of the AdaptResponse randomized study (NCT02205359). In AdaptResponse, investigators studied the hypothesis that cardiac resynchronization therapy (CRT) devices which utilised AdaptivCRT® (aCRT) algorithm (Medtronic) had better prognosis in patients with normal atrioventricular conduction and left bundle… View more

In 1941, Mahaim and Winston described the histology of anomalous connections that arise from the AV node and insert into the right ventricle.1 This was the first description of nodoventricular or so-called Mahaim accessory pathways. Accessory pathways with decremental conduction properties that connected the atrium to the right bundle branch (RBB) were subsequently mapped mainly at the lateral… View more
