Can the Vagus Nerve make your heart rate elevated?

I've had my resting heart rate stay elevated at various times above 100 BPM including one time for 3 hours. My usual is around 80. Cardiologist has checked me out and said heart looks fine but it could have been a vagus nerve thing. I thought that made your heart rate go down. Can it make it go up as well?
