Grave's Disease or HYPERthyroidism, means your body is always running at "double time" speed--metabolism, heart rate, oxygen consumption, etc. Medications that act as anti-histamines, or "non-drowsy" formulas and novocaine to the GD patient can actually increase your heart rate and lead to tachycardia--where your heart ineffectively "flutters" and does not pump blood effectively which can lead to cardiac arrest.
