The second most common form of supraventricular tachycardia (SVT) uses a second connection between the upper and lower heart chambers, a second "staircase". In this second type of tachycardia, the electrical signal goes down one staircase from the top chamber to the bottom chamber and then takes the second staircase from the bottom chamber and back up to the upper chamber. The electrical signal continues to take this path, as the tachycardia persists.
