case_images: a, b, and c represent a series of continuous cardiac activities monitored by a holter monitor. They exhibit two SAs: the first one lasts for 7.2 seconds, followed by an atrioventricular junctional escape rhythm, and then a second arrest of 3.8 seconds. SA: sinus arrest.

case_images: The Holter monitor revealed frequent SA, with the longest pause lasting 7.2 seconds (Figure 1).

case_images: In addition, the frequency of SA gradually decreased about 25 days after COVID-19 infection, and by day 29, electrocardiogram monitoring revealed almost no cardiac arrest, while reexamination of Holter monitor showed no evidence of SA (Figure 2).
