Research ArticleOpen accessIn the abstractFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDFCite
