I see all sorts in the ward rounds almost everyday. This is one typical finding on my patients. Most patients would be plastered with 3 such plasters on the chest when they present at the A&E, for cardiac rhythm monitoring. Once they are in the ward, often times, these plasters are conveniently forgotten; like this one for instance. And these plasters have a propensity to ‘migrate’ to other parts of the body (depending on how fitfully the patient slept!).
This one has migrated to the patient’s back, right about where the left renal angle is located.
Perhaps now we can use it to monitor some sort of ‘renal rhythm’ instead!
