Abstract

The cardiovascular system is vital for human survival. It has many functions and many components; the most important is the heart. The heart is a muscular organ that distributes blood throughout the cardiovascular system. Heart contraction is controlled by an electrical conduction system within the heart. The electrical activity can be visualized in a recording known as an electrocardiogram (ECG). This conduction system can malfunction causing a heart arrhythmia. Some heart arrhythmias can be dangerous, causing illness or death. Improved techniques in imaging have allowed the growth of the clinical discipline interventional electrophysiology. Medical personnel can now change some abnormal electrical patterns thorough a procedure known as the ablation technique.
