Post-Covid-19 Tachycardia Syndrome: A distinct phenotype of Post-acute Covid-19 Syndrome.

In this paper we highlight the presence of tachycardia in Post-acute Covid-19 Syndrome by introducing a new label for this phenomenon: Post-covid-19 tachycardia syndrome and argue that this constitutes a phenotype or sub-syndrome in PACS. We also discuss epidemiology, putative mechanisms, treatment options and future research directions in this novel clinical syndrome.
