New Imaging Technique Allows Study of Human Heart Conduction Fibers

The human heart has a simple function: it’s a pump that circulates fluid (blood) through a series of pipes (blood vessels). However, the mechanics behind this function are quite complex. They involve an intricate series of conducting pathways that allow for the generation of an electrical impulse that propagates in a specific way through the heart muscle in order to produce a synchronized and efficient contraction, or heartbeat. While scientists understand the theory behind the electrical impulses that control the heartbeat, the specifics of the conducting pathway have been difficult to study…until now.

MyHeartMap Challenge Inspires Pennsylvanians to Map AEDs

The University of Pennsylvania has been conducting a contest — the MyHeartMap Challenge — in which participants record locations of automated external defibrillators (AEDs) throughout the state. The purpose of the contest is to raise awareness about the importance and location of AEDs, and to build a statewide database of AED locations.
