Abstract

Two methods to record preatrial activity, that is, sinus node potential are presented. One, during right atrial catheterization through an electrode catheter, and the other, using transthoracic recordings with a high amplification and derivation of the electric signals. The sinus node potential duration represents the sino-atrial conduction time (SACT), a useful parameter for the sinus node function evaluation.
