There are many reasons for slow heart rate, including physiological factors and disease factors such as hypothyroidism and atrioventricular block.
1. Physiological factors: the slow heart rate of some patients is a normal physiological phenomenon, such as people who love physical exercise, due to the effective exercise of the heart, the function of the heart has been greatly improved, so the heartbeat will usually be slower. If there is no discomfort, there is no need for special treatment.
2. Disease factors: mainly caused by certain diseases, such as common hypothyroidism, atrioventricular block and so on.
(1) Hypothyroidism: It is mainly due to the low secretion of hormones by the thyroid gland, which leads to the slow heartbeat of the patient.
(2) Atrioventricular (AV) block: This is a condition in which the signaling pathway from the atria to the ventricles is damaged or interfered with, and the transmission speed is delayed or interrupted, which disrupts the heart’s normal rhythm, thus causing a slow heart rate to occur.
In addition, there are also drugs, sick sinus syndrome and so on can lead to the phenomenon of slow heart rate. If you are not feeling well, you should seek medical attention and follow your doctor’s instructions.
