the general name for any substance that causes the heart to beat faster is?

Answer 1

They're called positive chronotropes.

Some sub classifications of chronotropes include:

1) Sympathomimetic amines - they act on Alpha and Beta receptors. The ones that act on Beta 1 receptors are the positive chronotropes and include many of those listed above as well as the following - epinephrine, norepinephrine dopamine, dobutamine, and Isuprel.
2) Vagolytic drugs - They block the nerves that slow the heartrate (parasympathetic nerves, like the vagus nerve). The most common example is Atropine.

Of course there are numerous physical things that can be done to increase the heart rate (physical activity, hemodynamic shock, fear and anger, etc.) but this usually comes from a reaction involving chemicals that your body makes - like epinephrine.
