Mechanisms of ventricular arrhythmias: from molecular fluctuations to electrical turbulence.
Ventricular arrhythmias have complex causes and mechanisms. Despite extensive investigation involving many clinical, experimental, and computational studies, effective biological therapeutics are still very limited. In this article, we review our current

Osborn Waves: History and Significance [PDF]
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

Andersen-Tawil syndrome: report of 3 novel mutations and high risk of symptomatic cardiac involvement. [PDF]
IntroductionAndersen-Tawil syndrome (ATS) is a potassium channelopathy affecting cardiac and skeletal muscle. Periodic paralysis is a presenting symptom in some patients, whereas, in others, symptomatic arrhythmias or prolongation of QT in ...

ABSTRACT Background Coronary artery vasospasm following coronary artery bypass grafting (CABG) is a rare but potentially life‐threatening complication that can lead to myocardial ischemia, arrhythmias, and cardiogenic shock. Nitroglycerin‐resistant vasospasm, particularly involving the left main coronary artery (LMCA), poses significant diagnostic and ...

Neurogenic disturbances of cardiac rhythm [PDF]
Arrhythmias are disturbances of electrical activation of the heart and are commonly encountered clinical conditions. Although typically associated with cardiac pathology, they have also been described in stroke and epilepsy.

ABSTRACT Background The effects of phosphodiesterase 5 (PDE5) inhibitors on the incidence of long‐term outcomes in patients with cardiovascular disease are not well understood. Objective: We studied the association between PDE5 inhibitor therapy and the incidence of adverse cardiovascular major adverse cardiovascular events (MACE) in patients ...

Increased levels of sST2 in patients with mitral annulus disjunction and ventricular arrhythmias
Objective Displacement of the mitral valve, mitral annulus disjunction (MAD), is described as a possible aetiology of sudden cardiac death. Stress-induced fibrosis in the mitral valve apparatus has been suggested as the underlying mechanism.

Aims Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in heart failure. However, prediction of the outcome remains difficult. We aimed to investigate for echocardiographic predictors of ventricular arrhythmias and fatal outcome and
