Hello, I'm NawlinWiki. I wanted to let you know that I undid one or more of your recent contributions to Pressure-volume loop analysis in cardiology because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! NawlinWiki (talk) 20:49, 16 April 2013 (UTC)
