View larger version (29K): [in a new window]   Figure 1 Cardiac compass report. The atrial pacing therapies were activated on January 20. The vertical dashed line indicates the last device interrogation. The atrial tachycardia (AT)/atrial fibrillation (AF) Patient Check indicates the days that the patient used his or her activator because of symptoms. The patient received the activator at the time of randomization. CV = cardioversion.

The graph shows the intervals between atrial (A-A) and ventricular (V-V) events at episode onset, detection, first therapy, and termination. The Ramp therapy was initiated 3.8 min after detection and resulted in the immediate termination of the atrial tachyarrhythmia. AF = atrial fibrillation.
