number of studies of genetic and molecular effects on rrhythmogenesis are noteworthy. ong QT syndrome (LQTS). Despite the great advances n our understanding of the role of channel disorders as auses for the LQTS, at present in at least 25% of these atients no genetic defect has been established. The idenified mutant genes are responsible for coding either the lpha (membrane spanning) or rarely ...
متن کاملInterventional cardiac magnetic resonance imaging in electrophysiology: advances toward clinical translation.
T echnical advances in cardiovascular electrophysiology have resulted in an increasing number of catheter abla-tion procedures reaching 200 000 in Europe for the year 2013. 1 These advanced interventions are often complex and time-consuming and may cause significant radiation exposure. 2 Furthermore, a substantial number of ablation procedures remain associated with poor (initial) outcomes and ...
متن کاملAdvances in Arrhythmia and Electrophysiology Applications of Cardiac Magnetic Resonance in Electrophysiology
Because of its wide availability, echocardiography is the most frequently used modality for diagnosis of the underlying substrate for cardiac arrhythmia. However, echocardiography is unable to visualize intramyocardial substrates for reentrant arrhythmia such as fat or scar fibrosis. Replacement of myocytes with nonviable tissue results in hypertrophy of the remaining viable cells and is associ...

A denosine is an endogenous nucleoside that has potent electrophysiologic effects.1-4 As an antiarrhythmic agent, adenosine has several unique properties: 1) it is an intermediate metabolite (Figure 1), 2) it has a very short half-life (less than 1.5 seconds), 3) its effects are mediated by specific membrane receptors coupled to guanine nucleotide binding proteins (G proteins), and 4) it has si...
