Atrial tachycardia and other ectopic atrial rhythms occur when a site outside of the sinus node, but within the atria, creates action potentials faster than the sinus node. This ectopic focus ...

higher automaticity – ectopic beats; and re-entry – atrial tachyarrhythmia; and higher vulnerability to arrhythmia – heart rate and its variability. Most of these predictors are not ready ...

Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles. Thus, each QRS complex will ...
