The book "Standardization of Zebrafish ECG Model" offers a comprehensive analysis of the use of zebrafish as a model organism in genetic and toxicological research. Zebrafish, known for their unique genetic traits and the possibility of ethical experimentation, have established themselves in recent years as a valuable tool for investigating environmental influences and pharmaceutical substances. The work highlights the development and standardization of electrocardiogram (ECG) models in zebrafish, which are significant for assessing toxicity and other biological responses. The author, Saravana Kumar, shares his expertise to discuss the relevance and challenges of applying these models. The book is aimed at researchers, students, and professionals engaged in the application of zebrafish in biomedical research.
