DescriptionE269 (CardioNetworks ECGpedia).jpg This is an interesting EKG as it shows paced atrial rhythm with a bipolar atrial pacemaker. In this case the lead configuration...

There is then a retrograde P that is sensed by the atrial channel of the pacemaker and a pacemaker mediated tachycardia begins. The tachycardia stops...

atrial fibrillation can "cure" a sick sinus patient of their bradycardia and the need for a pacemaker. In those cases though that convert to atrial fibrillation...

DescriptionE0003141 (CardioNetworks ECGpedia).jpg This is an interesting case of bigemini. The pacemaker is an atrial pacer set at 30/min. Note the marker channel...
