Hyperthyroidism, the problem itself, needs to be treated for at least a year, and some patients even need lifelong treatment. Only when hyperthyroidism itself is effectively controlled will the heart problems caused by hyperthyroidism improve. If hyperthyroidism is not improved, hyperthyroid heart disease will develop and patients will experience chest tightness, panic attacks, palpitations and chest pain from time to time. As for how long it takes to treat, it is difficult to generalize because the treatment of hyperthyroidism itself is a long process. As for how long it takes to treat, it needs to be evaluated by regular review of electrocardiogram, thyroid function five and heart ultrasound.
