Mechanisms of Atrial Arrhythmias: Insights from the by Michael A. Colman

By Michael A. Colman

This thesis describes the advance of biophysically specific machine versions of the human atria and torso to review the underlying mechanisms of cardiac illnesses, the most universal explanations of morbidity and mortality. it is a cross-disciplinary undertaking, regarding basics of cardiac electrophysiology, physics of excitable media, utilized arithmetic and excessive functionality clinical computing and visualisation. the writer makes use of machine types to supply insights into the underlying mechanisms of the genesis of atrial traumatic inflammation and develops novel suggestions for the tracking of atrial tachycardia.

Example text

The mathematical approach and assumptions used are still used today. The gross kinetics of an ion channel are modelled through the use of activation and inactivation variables, corresponding to the activation and inactivation gates. It is assumed that the activation and inactivation gates are independent of each other. The activation variable corresponds to the fraction of channels that are in the activated state. Hence, a value of 0 represents none of the channels being activated, and a value of 1 represents all of them being activated.

The exact range and clamp time is dependent on the current being measured. Either the peak current during the test potential, the current at the end of the test potential or the tail current (the current just after the voltage is stepped back to the holding potential) is returned (illustrated in Fig. 13a-ii). These data can be used to create a current–voltage (I–V) relationship: The current (whichever value is used) is plotted against the test potential (Fig. 13b). This provides an indication of the voltage ranges in which the current is most active.

In this example, it can be seen that the absolute ERP and the difference in ERP between the two regions defines whether a stable re-entrant circuit can be permitted. 4 Experimental Techniques This section discusses a range of experimental techniques used to either characterise APs and currents or cardiac organ structures.
