Abstract :
Using a new mathematical model of SA node activity and its vagal modulation, we were capable of reproducing the complex recovery kinetics in the chronotropic response following prolonged vagal stimulation, including postvagal tachycardia. We propose that these components of recovery are due to underlying mechanisms inherent in the SA node
