Mode switching of dual chamber pacemakers from activation of a blanked flutter search algorithm by a single atrial event.

The Medtronic Kappa 700 and 900 pacemaker family offers a dedicated Blanked Flutter Search algorithm specifically designed for the detection of atrial flutter. This report describes 5 cases that demonstrate how the Blanked Flutter Search algorithm can be activated in the absence of atrial tachycardia, atrial flutter, or sinus tachycardia by a single atrial event (AR) detected in the atrial refractory period of the pacemaker provided it is either preceded or followed by a sensed atrial event (AS).

Repair of acute ascending aorta-arch dissection with continuous body perfusion: a case report.

An approach for the replacement of the distal ascending aorta-proximal arch and acute dissection is described. During the operation, the patient's entire body was continuously perfused, the aortic arch was excluded from the arterial circulation, and the aorta was not clamped at any time. To achieve continuous body perfusion, we independently cannulated the right axillary and the left femoral arteries.
