Atrial Tachycardia
With atrial tachycardia, the electrical impulse comes from somewhere in the atria, the heart's upper chambers, other than the sino-atrial (SA) node, a small mass of tissue near the right atrium that sets the pace for the heartbeat. The alternate origin of the electrical impulse causes a fast heart rate.
