Patient demographic and characteristics pertinent to the finding of arrhythmia

Pt	Age (years)	Arrhythmia	Comorbidities	HCQ ± AZN	QTc prolonged	Echo findings	SF by echo (%)	EF by echo (%)	High-sensitivity troponin T (ng/L)	Circumstances
1	12	Monomorphic VT	Sickle cell disease	No	No	Mild LV dilation with preserved ventricular function	36	59	<6	None
2	20	Monomorphic VT	Lymphoma, mediastinal mass, pericardial effusion	No	No	Large circumferential pericardial effusion	33	69	10	None
3	13	Sustained atrial tachycardia	Myocarditis secondary to COVID-19	No	No	Mild LV dysfunction	32	49	398	High-dose epinephrine and nor-epinephrine drips
4	13	Monomorphic VT	Bloom syndrome, history of testicular cancer	No	No	Mild-to-moderate LV dysfunction	25	46	<6	None
5	17	Monomorphic VT	Myocarditis secondary to COVID-19	No	No	Normal structure and function	31		4013	None
6	16	Monomorphic VT	Acute lymphocytic leukemia, mediastinal mass, pericardial effusion	No	No	Normal structure and function	NA	65	12	HypoMg, HypoK, and HypoCa

AZN = azithromycin; EF = ejection fraction; HCQ = hydroxychloroquine; HypoCa = hypocalcemia, HypoK = hypokalemia, HypoMg = hypomagnesemia; LV = left ventricular; NA = not applicable; Pt = patient; QTc = corrected QT; SF = shortening fraction, VT = ventricular tachycardia.
