Long-term incubation with COVID19 patient serum also had effects on cellular arrhythmogenic potential: Ca 2+ waves showed a trend to occur more often upon incubation with patient serum as compared to control (0.22 ± 0.04 vs 0.37 ± 0.04 (control vs patient), waves/sec, n = 32 vs 49, p = 0.079) and spontaneous Ca 2+ release events (i.e.
