The main symptom of arrhythmophobia is extreme anxiety when faced with numbers, chills, dizziness and lightheadedness, excessive sweating (hyperhidrosis). Heart palpitations, nausea, shortness of breath (dyspnoea). Tremors or tremors, stomach upset, or indigestion (dyspepsia). Fear of numbers is called arithmophobia.

This fear is somewhat unusual, as it encompasses a wide variety of specific phobias, including generalized fear of all numbers and fear of specific numbers. In the case of arithmophobia, the feared stimulus has to do with calculation, numbers, arithmetic or mathematics. In this way, the person who suffers from this alteration is disproportionately afraid of these elements.
