Hypothyroidism can be accompanied by pathological bradycardia, which is a slowing down of the heart rate in adults below 50-60 beats per minute. Slowing down the heart rate makes even the simplest activities very tiring.
Symptoms of bradycardia caused by hypothyroidism increase gradually, making it difficult for both the patient and the doctor to make a proper diagnosis. The most common symptoms of bradycardia:
In more severe cases, bradycardia can lead to fainting and even death. If the patient suspects that the heart is beating too slowly, they should see a doctor. In the case of bradycardia associated with the risk of asystole or severe symptoms, pharmacological treatment is used. If bradycardia persists, transvenous stimulation should be considered, which involves inserting an electrode through the vessels directly into the heart. The causes of the heart beating too slowly should always be sought because eliminating it may prevent the implantation of a pacemaker.
