Recommend using Guthook’s AT Hiker App (iOS, Android), which is quite useful if you want to pinpoint your location along the trail with a Smartphone GPS (which can still operate when it’s not connected to cell phone service.) It’s better than carrying a trail map because it’s always up-to-date and the app lets you share information with other nearby hikers (like local Wifi passwords, the location of good campsites, water availability, and shelter conditions) using a virtual trail register capability. While you can carry a paper version of the AT Guide or tear out pages from it, I refer to a PDF version of it and Guthook’s App on my smartphone. Like it or not, a smartphone has become an essential on the Appalachian Trail. (See the Appalachian Trail Cell Phone Guide)

Myocardium, that's because myocardium simply means 'muscular tissue of the heart'. It is not pericardium or connective tissue as these are only small, specific areas of the heart and a heart attack can cause cells to die anywhere in the heart.
