Cardiac modeling is a research area that focuses on creating mathematical and computational models to simulate the behavior of the heart. These models can be used to study the electrical and mechanical functions of the heart, as well as to predict how the heart will respond to different stimuli or conditions. Cardiac modeling is used in a variety of applications, including understanding the mechanisms of heart diseases, designing new treatments and therapies, and optimizing the performance of medical devices such as pacemakers and defibrillators. By accurately modeling the complex behavior of the heart, researchers can gain valuable insights into its function and potential treatments for cardiovascular diseases.
