COVID-19 can disrupt the heart’s electric system, according to a report undergoing peer review at a Nature Research journal.
The heart pumps blood by sending electrical signals through its “conducting cells” to tell “muscle cells” to contract. Normally, each conducting cell activates the one next to it in a domino effect to ensure smooth contractions.
An autopsy of a COVID-19 patient found the virus had infected her heart in an unusual patchy pattern, “with small islands of infected cells here and there,”
