In spite of study findings that incriminated hyperkalemia as the toxic factor of cardioplegic solutions, the results of later experiments documented the safety and effectiveness of osmotically balanced hyperkalemic solutions in patients undergoing cardiac surgical procedures. The concepts of hyperkalemic cardioplegia and the early animal and clinical studies leading to its reintroduction as a useful adjunct in cardiac surgical procedures are referenced in this report.

UI	MeSH Term	Description	Entries
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D002314	Cardioplegic Solutions	Solutions which, upon administration, will temporarily arrest cardiac activity. They are used in the performance of heart surgery.	Cardioplegic Solution,Solution, Cardioplegic,Solutions, Cardioplegic
D006324	Heart Arrest, Induced	A procedure to stop the contraction of MYOCARDIUM during HEART SURGERY. It is usually achieved with the use of chemicals (CARDIOPLEGIC SOLUTIONS) or cold temperature (such as chilled perfusate).

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
