Atrial Arrhythmias in Patients with Severe COVID-19

Table 4

The correlation between arrhythmias and cardiomyocyte injury markers (Spearman).

Variable (N = 84)	Correlation coefficient	value
PAC
CKMB	0.40	<0.01
hscTnI	0.20	0.08
Myoglobin	0.20	0.17
NSAT
CKMB	0.40	<0.01
hscTnI	0.20	0.10
Myoglobin	0.10	0.28

CKMB, creatine kinase isoenzyme; hscTnI, high-sensitive cardiac troponin I; PAC, premature atrial contracts; NSAT, nonsustained atrial tachycardia.
