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.

Heart Conditions Don’t Just Affect Older Adults

This article was written by Julianne Wyrick.

February is American Heart Month. Sponsored by the American Heart Association, American Heart Month is a time to battle cardiovascular disease and educate people on what they can do to live heart-healthy lives. Heart disease, including stroke, is the leading cause of death for men and women in the United States.

How much do you know about the condition of your heart? Heart health awareness typically focuses on heart disease in older adults caused by an unhealthy diet and a lack of exercise. But what if you could be at risk for cardiac arrest and sudden death even though you are young and in shape?
