Cardiac dynamics refers to the study of the electrical and mechanical activity of the heart, particularly in relation to its pumping function. This field of research focuses on understanding the physiological processes that control the heartbeat, as well as how abnormalities in these processes can lead to conditions such as arrhythmias, heart failure, and other cardiovascular diseases. Researchers in cardiac dynamics use various techniques, such as electrophysiology, imaging, and computational modeling, to study the complex interactions between different components of the heart and how these interactions affect overall cardiac function. Ultimately, the goal of cardiac dynamics research is to improve our understanding of heart health and to develop new treatments for heart-related conditions.
