Cardiomegaly is drawing 437x more Wikipedia traffic than normal

What this article is

Cardiomegaly is a medical condition in which the heart becomes enlarged. It is more commonly referred to simply as "having an enlarged heart". It is usually the result of underlying conditions that make the heart work harder, such as obesity, heart valve disease, high blood pressure (hypertension), and coronary artery disease. Cardiomyopathy is also associated with cardiomegaly.

What changed that day

How this was measured

Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
