Summary

The concept of cardiac remodeling and reverse remodeling as both a cause and an effect of cardiac pathophysiology is fundamental to understanding arrhythmogenesis. The arrhythmogenic potential is thought to come from structural and functional changes in properties. More and more evidence suggests that alteration in organ function can lead to modified structure and modified structure to altered function. This intricate “yin-yang” reveals the complex and continuous adaptation of the heart. In this chapter we review the diverse forms of remodeling and the limited remodeling found in different pathologies.
