Happy Friday everyone! This week's picture is not of a heart per se, but of someone wearing a Holter monitor. It's basically an EKG recorder that one wears around for a while, and it keeps a record of the electrical signals. They're typically used (as I understand it) to find elusive electrical problems with the heart that don't show up during, say, a short office visit.

Here's hoping Ms.Kashner's heart is doing fine.
