Abstract

Circadian and infradian rhythmometry can and should be applied for the "isolation" of components in a broad spectrum of rhythms with different frequencies that can characterize the occurrence, among other pathologies, of ischemia in the electrocardiogram (ECG). Analyses of data from the literature on the recurrence of cardiac ischemia in a 12-day electrocardiographic record show two phase-drifting, internally and externally desynchronized, circadian rhythmic components and an infradian about-half-weekly modulation. ECGs covering spans much longer than 12 days are indicated in order to distinguish transient phase-drifts from long-maintained desynchronization. To assess the importance of such phenomena for diagnosis, prognosis, and treatment, a recording with accompanying as-one-goes analyses of data is indicated.
