Lack of temporal correlations between COVID pandemic waves and the occurrence of malignant ventricular arrhythmias
© The Author(s) 2023. Published by Oxford University Press on behalf of the European Society of Cardiology..
AIMS: Correlations between malignant ventricular arrhythmias and the COVID waves have never been investigated.
METHODS AND RESULTS: Prevalence of malignant ventricular arrhythmias/sudden cardiac death has been correlated to the four COVID waves between the onset of pandemic and end 2021. No significant correlation was present in the temporal evolution of both COVID patients/positive tests and incidence of malignant ventricular arrhythmias, which tended to decrease after vaccination onset.
CONCLUSION: We present evidence of complex higher-order periodicities and the co-existence of such regions with stable non-chaotic areas in ex vivo human hearts. We infer that the oscillation of the calcium cycling machinery is the primary mechanism of higher-order dynamics. These higher-order regions may act as niduses of instability and may provide targets for substrate-based ablation of VF.
