Fast heart rate: Have you had a monitor during the episodes? It is difficult to answer without documentation of the heart rate and rhythm during an episode of your symptoms.

Intensity?: You may be working at too high intensity.Also make sure your minerals are being replaced if sweating profusely with exercise. Try to cool down before stopping exercise.
