• Ectopic foci are also known as ectopic pacemakers.
• Increased potassium conductance should stabilize membrane potential during ischemic insults, reducing the extent infarct and ectopic pacemaker activity.
• Changes in electrolyte balance, or development of ectopic pacemaker activity, disrupt normal heart hypoxia, acidosis and drug toxicity.
• It can be considered a form of ectopic pacemaker activity that is unveiled by lack of other pacemakers to stimulate the ventricles.
