An electrocardiograph (ECG) on hospital day 4 (before initiation of HCQ) was normal, with a corrected QT interval (QTc) of 397 ms. On the seventh day of hospitalization, repeat ECG before the morning dose of HCQ showed a new right bundle branch block (RBBB) and critically prolonged QTc (631 ms) ( Figure 2 ). Lopinavir/ritonavir is also associated with the prolongation of QTc, but the ECG after starting this medication was normal.	./cache/cord-290955-m2igkcxv.txt	./txt/cord-290955-m2igkcxv.txt
