Die Ergebnisse der elektronenmikroskopischen Untersuchungen von Ventri keln des Myokards verschiedener Wirbeltiere zeigen nach den bis heute angewand ten Methoden, da es erhebliche Unterschiede einerseits zwischen dem Herz muskel der Fische, Amphibien und Reptilien und andererseits dem der Suge tiere gibt. Die Herzmuskelzellen der Kaltblter weisen ein kaum entwickeltes sarko plasmatisches Reticulum (SR) auf (Frosch: Scheyer, 1960; Huang, 1967; Staley und Benson, 1968; Sommer und Johnson, 1969, 1970; Axolotl: Howse et al., 1969; Gros und SchrEwel, 1970; Schildkrte: Fawcett und Selby, 1958; Bergman, 1960; Boa constrictor: Leak, 1967). Sie besitzen kein transversales tubulres System (TSystem) (Frosch: Staley und Benson, 1968; Sommer und Johnson, 1969, 1970; Axolotl: Howse et al., 1969; Gros und SchrEwel, 1970; Schildkrten, Salamander, Fische: Howse et al., 1970; Schildkrte: Hirakow, 1970; Necturus: Hirakow, 1971; Boa constrictor: Leak, 1967), und es fehlt der Nexus zwischen den Myokard zellen (Frosch: Staley und Benson, 1968; Sommer und Johnson, 1969, 1970; Axolotl: Howse et al., 1969; Gros und Schnlvel, 1970).
