<title>Model Structure</title>
<para>
The ionic mechanisms underlying many important properties of the human atrial action potential are poorly understood. Using specific formulations of the K<superscript>+</superscript>, Na<superscript>+</superscript> and Ca<superscript>2+</superscript> currents based on experimental data recorded from human atrial myocytes, along with representations of pump, exchange and background currents, Marc Courtemanche, Rafael J. Ramirez and Stanley Nattel developed a mathematical model of the action potential (see the figure below).
</para>
<para>
This mathematical model builds mostly on the classical work of Luo and Rudy (see The Luo-Rudy Ventricular Model II (dynamic), 1994). Courtemanche <emphasis>et al</emphasis> effectively develop a working model of the human atrial action potential from the Luo-Rudy model which is based on guinea pig ventricular cells. Their primary goal was to develop a useful model of the action potential from which they could gain insights into experimental observations made on human atrial cells and tissues and make predictions regarding the behaviour of these cells under previously untested conditions
