Basically, does hyperglycemia increase or decrease heart rate?

In brief: Decrease

In general it decreases.
When cells are bathed in too much glucose this changes the osmotic potential and they get sluggish and lethargic. Not enough blood glucose (hypoglycemia) tends to cause the opposite including adrenaline surge in the body that increases heart rate.
