The presence of near one hour ultradian cardiac rhythm was revealed on the ECG of 24 patients with acute myocardial infarction during 24-hour Holter monitoring. A classification of the phases of near one hour rhythm was developed according to the first coefficient value of autocorrelation of cardiac rhythm function. Special attention was attracted to the critical phase indicating high probability of the development of terminal arrhythmia and the threatening phase preceding it. Peculiarities of the variational structure of cardiac rhythm in the threatening phase and physical prerequisites of its origination are discussed.
