Enables chronic His-Purkinje recordings in experimental models; leaves open translation to clinical electrophysiology.
By utilizing cardiopulmonary bypass, permanent electrodes with external leads have been sutured over the bundle of His and the Purkinje-papillary junction of the right anterior papillary muscle. For the first time this technic allows the activity of the specialized conducting system to be studied directly over extended periods of time and permits observations to be made not feasible in acute experiments.

Stuckey et al. (1961) studied this question. Chronically implanted electrodes was evaluated. Chronically implanted permanent electrodes sutured over the bundle of His and Purkinje-papillary junction allow direct study of the specialized conducting system over extended periods.
