The technical name is Commotio cordis. It simply means a shot to the chest (or, literally from the Latin, "agitation of the heart"). Doctors describe it as a sudden, blunt, and innocuous-appearing trauma to the chest that results in cardiac arrest and sudden death. The shot to heart occurs during what medical experts call "a window of vulnerability" during the 10- to 30-millisecond moment between heartbeats. The U.S. National Commotio
Registry records 224 fatal cases of Commotio cordis from 1996-2010. It's the No. 1 killer in U.S. youth baseball.
Here's how one cardiologist described the concealed trauma of Commotio cordis: "When you get a trauma to any muscle you can see it bruise and swell. When it happens to your arm or leg you can see that directly too. But when it happens to your heart, you can't see the trauma because it's covered by the chest and the ribs."
How many people in your path today are struggling from spiritual, relational, or emotional commotio cordis? Perhaps they've taken a shot to the heart at a vulnerable time in their lives, and yet no one sees the pain. Perhaps that pain has caused an emotional or relational death in their lives, and still they go on day after day hoping that no one sees that they are really struggling.
Our job as Christians is to ask God to so fill us with His Holy Spirit, that we will be aware of the emotional and spiritual trauma that many people experience. We can bring aid and comfort to them if we allow God to lead us.
