Patient discussion about racing

Q. what causes the heart to race so fst it feels like it going to come right out your chest?

A. Too much caffeine or alcohol or food can sometimes cause your heart to race in an erratic way. http://www.sciencedaily.com/releases/2008/01/080111201910.htm Heart rhythm problems (arrhythmias) occur when the electrical impulses in your heart that coordinate your heartbeats don't function properly, causing your heart to beat too fast, too slow or irregularly.

Arrhythmias are common and usually harmless. Most people have occasional, irregular heartbeats that may feel like a skipped, fluttering or racing heart. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms.
