Figure 3: Rate response profile from telemetry in the VVIR mode during corridor walk in a patient with underlying atrial fibrillation (Patient 1). The top graph shows the activity counts in arbitrary units, which were used to calculate the sensor indicated rate (solid line, lower graph). In this patient with intrinsic rhythm, only the calculation rate from the sensor is shown, which increased from the lower rate of 50 bpm to the activity of daily living (ADL) rate of 95 bpm. Vector 3 of the intracardiac accelerometer was the chosen vector.
