Mean ± SD values of the proposed indexes in the four analyzed phases: sinus rhythm (SR), sinus rhythm during isoproterenol infusion (SRISO), atrial fibrillation (AF) and atrial fibrillation during isoproterenol infusion (AFISO) for Atrial Signals (AS) and LAP series.

p < 0.0001 the comparison of a same rhythm before and during isoproterenol infusion.

The t-test comparing organized (SR) to not organized (AF) rhythms always results significant (* p < 0.0001).
