AI Article Synopsis
- A new tissue bath system was created to study heart tissues without needing complicated machines.
- It uses a special chamber to keep the heart tissues in a warm, controlled environment so scientists can test them easily.
- The results show that this system works well, keeping the heart tissues alive and allowing researchers to study how they respond, similar to earlier methods used on living animals.
Article Abstract
A tissue bath system, to be used as an alternative to complex perfusion chambers, was constructed for use in cardiac electrophysiological studies. This system consists of an acrylic chamber to hold circulating physiological medium such as DMEM, suspended in a water bath warmed by a hot plate. Temperature and pH were controlled to mimic physiological conditions. Rat and porcine cardiac tissues, were used to test viability of the conditions presented in the bath system. Using a cardiac mapping system, the tissues were stimulated and responses recorded. From the recordings we were able to calculate conduction velocities and spatial dispersion of activation indices. The results are comparable to previous in-vivo work, which suggests that the tissue bath system design can maintain tissue viability. This tissue bath system is a relatively simple alternative for ex-vivo testing of cardiac tissues.
