Centrifugal Geometric Scanning — an Alternative Concept in Pacemaker Treatment of Tachycardias
Short term efficacy and safety of a new scanning concept for termination of AV reciprocating tachycardias were assessed in five patients, two with dual AV nodal pathways and three with an accessory A V connection. The concept includes geometric partioning of the scanning interval concentrating the attempts to its early part, a centrifugal search outwardly from a memorized extra stimulus delay and alternation of the number of extrastimuli. After initial definition of the termination characteristics in each patient the system was found efficient during a 48-hours recorded period. No adverse effects were observed.
