Afterdepolarizations cause triggered arrhythmias. One kind occurs after repolarization is complete, delayed afterdepolarizations (DADs). Another occurs as an interruption in repolarization, early afterdepolarizations (EADs). Afterdepolarizations initiate arrhythmias when they depolarize membrane potential to threshold potential for triggering action potentials. 
Mechanisms and incidence of torsades de pointes tachycardia
In patients with acquired atrioventricular block females developed TdP at QT intervals shorter than males, indicating that there must be other sex specific factors that increase the risk of arrhythmias. Expand
Epirubicin-induced QT prolongation, monomorphic ventricular tachycardia, and response to beta blockade in long QT syndrome type 2
The consequence of exposing a patient with congenital LQTS to epirubicin is illustrated and a successful protection strategy against ventricular arrhythmia by propranolol is described where metoprolol proved to be less effective. Expand

The results suggest that redox-activated PKA may be important for H2O2-dependent arrhythmias and could beImportant for development of specific antiarrhythmic drugs. Expand
Isoliensinine Eliminates Afterdepolarizations Through Inhibiting Late Sodium Current and L-Type Calcium Current
It is revealed that IL effectively eliminated EADs and DADs through inhibiting I NaL and I CaL in ventricular myocytes, which indicates it has potential antiarrhythmic action. Expand

This finding supports a role for inhibition of this enzyme, either directly or by inhibition of upstream kinases, to prolong QT through mechanisms that are being worked out, but include enhanced inward 'late' sodium current during the plateau of the action potential. Expand

The results suggest that augmented I NaL alone is sufficient to induce AF, and EB exerts anti-AF actions mainly via blocking INaL, which put forward the basis of pharmacology for new clinical application of EB. Expand
Myocardial repolarization time, J-point to T-peak and T-peak to T-end intervals, have different heart rate dependency and autonomic nerve interference in healthy prepubertal children.
Tpe had lower heart rate dependence and a lower degree of autonomic nervous interference than did JTp, and the degree of coherence with RR interval variability was calculated using spectral analysis. Expand

Growth in understanding the cellular and molecular mechanisms involved in the cardioprotective response can lead to the development of new pharmacological and non-pharmacological strategies forCardioprotection, thus contributing to increasing the efficacy of IHD treatment. Expand

Early afterdepolarizations and cardiac arrhythmias.
Evidence that deterministic chaos underlies the irregular behavior of EADs is shown and mechanisms by which chaotic Eads synchronize in large numbers of coupled cells in tissue to overcome source-sink mismatches are discussed. Expand

Molecular physiology of cardiac repolarization.
It has become clear that cardiac ion channels function as components of macromolecular complexes, comprising the alpha-subunits, one or more accessory subunit, and a variety of other regulatory proteins, suggesting important functional links between channel complexes, as well as between cardiac structure and electrical functioning.

Effects of verapamil on ventricular tachycardias possibly caused by reentry, automaticity, and triggered activity.
It is suggested that verapamil does not affect VT caused by reentry and catecholamine-sensitive automaticity but is effective in suppressingVT caused by triggered activity related to delayed afterdepolarizations in humans. Expand

Effect of Adenosine and Verapamil in Catecholamine‐Induced Accelerated Atrioventricular Junctional Rhythm: Insights into the Underlying Mechanism
The mechanism of catecholamine‐induced accelerated AV junctional rhythm is most likely enhanced automaticity, and catechlamine‐ induced accelerated AV functional automaticity is sensitive to adenosine and verapamil. Expand
Mechanism-specific effects of adenosine on atrial tachycardia.
Findings demonstrate that adenosine's effects on atrial tachycardia are mechanism specific and can be used to differentiate between reentrant tachycardsia confined to the region of the sinus node or atria and between nonreentrant atrialTachycardIA due to either triggered activity or automaticity.
