Just wondered if any of you ladies had been diagnosed with high noradrenaline? I am under the care of a cardiologist for tachycardic episodes and he did catecolamine testing several times and my noradrenaline is 2.5x the normal limit. Adrenalin and dopamine all normal. Having MRI to look for adrenal tumour. Anyone else had this blood result? I'm hoping it's a crazy menopause thing.
