Electrocardiographic mapping in a realistic torso tank preparation demonstrated utility in capturing the dynamic nature of acute ischemia and revealed the need to consider geometrical relationships.
An isolated heart preparation in a realistic torso tank is a useful model for mapping transient myocardial ischemia and highlights the importance of geometrical relationships in electrocardiographic mapping.

Supports torso-tank models for dynamic ischemia mapping; leaves open clinical translation of geometrical factors in ECG interpretation.
Presents preliminary findings of mapping transient myocardial ischemia in an isolated heart preparation suspended in an instrumented, human shaped, electrolytic torso tank. The preparation allows the authors to record both epicardial and tank surface potentials simultaneously and thus capture the dynamic nature of acute ischemia through repeated episodes. The authors' results demonstrate the utility of the preparation and reveal the need to consider geometrical relationships when using electrocardiographic potentials to estimate cardiac activity.

MacLeod et al. (2002) studied Transient myocardial ischemia. Electrocardiographic mapping in a realistic torso tank preparation was evaluated on Epicardial and tank surface potentials. Electrocardiographic mapping in a realistic torso tank preparation demonstrated utility in capturing the dynamic nature of acute ischemia and revealed the need to consider geometrical relationships.
