SUPRAVENTRICULAR TACHYCARDIA (SVT)

How does the Heart Conduction System Work?

The heart relies on an electrical signal generated from its own “pacemaker”, the sinoatrial node, and conducted through the right atrium to the “gatekeeper”, the atrioventricular node, which slows the impulse to allow the heart to fill with blood prior to each contraction. The signal then travels down to the bottom chambers of the heart and spreads leftward and   rightward   simultaneously.   Arrhythmias  occur when the electrical signal is disrupted, causing the heart to beat very fast, slow, or erratically. 

What Triggers an Arrhythmia or SVT?
