ABSTRACT
To examine a circadian variation of symptom onset of acute myocardial infarction and unstable angina two years register of possible all acute coronary events in a population of Podhale was performed. The time of onset of acute coronary events was determined on the basis of patient self-report. One criterion for exclusion in the study was inability to establish reliable time of onset of acute symptoms. The study group comprised 366 patients aged 61 years, range 29-89 years, men 212, mean age 59, women 154, mean age 64. The distribution of symptom onset within 24 time intervals tested for uniformity by a chi-square test for goodness of fit shows significant (p < 0.01) morning peak between 7:00-9:00 A.M. in whole group and in a subgroup of AMI. No significant evening peak (17:00-18:00 P.M.) was also found in subgroup of AMI.

A case of ventricular fibrillation during holter monitoring is described. Tape analysis doesn't shows any significant changes of QT intervals, increasing in heart rate and ventricular ectopic activity. It was attempt possibility that modulated parasystole may lead to ventricular fibrillation.
