Eliminate the work of storming around the room.

Yes the heart is a muscle and working that muscle works that muscle.
It is a very important muscle but it is a relatively small efficient muscle.
The heart alone does not consume a lot of calories.

If you are working legs and the legs ask for fuel and oxygen and that causes the heart to beat faster that is different. Now you are working the legs, lungs, and the heart.

The heart rate will also elevate to help cool the body. The vessel dilates on you pump more blood near the surface of the skin.

You will see some misguided analysis that you burn more calories in a hot Yoga as the heart rate is elevated. They take a simple metric heart rate = calories.

A similar question was asked of Cecil Adams in his Straight Dope column about the differences in heart rate between exercising and caffeine. I think that the central takeaway is similar in both cases. Cardio exercise is not about raising the heart rate — that's just a handy metric for measuring relative effort — but about exercising all of the systems of the body, training them to work efficiently together. Raising your heart rate through caffeine or emotion is like revving your car engine. It consumes fuel. It adds strain to the system. It doesn't actually do anything very useful.

Your proposed workout would give you some small amount of exercise, but no more than stomping through the room would have done before, and you're increasing your stress hormone levels, which has notable negative effects.
