Brain ≈ Heart Rate: Without brain input, heart rate ~110 bpm. Heart, (like rest of our body) & heart rate constantly split second controlled from brain. Vagal acetylcholine release slows rate, sympathetic adrenaline/noradrenaline release increases rate. Fear/anger/stress (subconscious), high thyroid hormone, low heart output (for whatever reasons) & re-entry circuits are common reasons for rapid heart rate.
