These discussions illustrate that the diastolic phase is not simply a period of rest but rather involves highly regulated and dynamic Ca(2+) fluxes.</p>","PeriodicalId":520753,"journal":{"name":"Physiology (Bethesda, Md.)","volume":" ","pages":"308-23"},"PeriodicalIF":8.4,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1152/physiol.00021.2012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30946057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
