Introduction
A pulse rate of about 40 beats per minute is usually abnormal. Normally, the pulse ranges from 60 to 100 beats per minute. A pulse rate below 60 beats per minute is considered sinus bradycardia. Bradycardia may be caused by various factors, such as pathological changes in electrocardiogram, problems with the heart's conduction system, medication side effects, hypothyroidism, etc.
A pulse rate of around 40 beats per minute is usually abnormal. Detailed analysis is as follows:
Under normal circumstances, the pulse ranges from 60 to 100 beats per minute. A pulse rate below 60 beats per minute is considered sinus bradycardia. Bradycardia may be caused by various factors, such as pathological changes in electrocardiogram (ECG), problems with the heart's conduction system, medication side effects, or hypothyroidism. Some individuals naturally have a lower heart rate; if they experience no other symptoms or significant discomfort, specific treatment is generally not required. However, if bradycardia is accompanied by symptoms such as dizziness, fainting, chest tightness, shortness of breath, or palpitations, immediate medical attention is recommended. Relevant examinations and treatments should be conducted to identify the underlying cause and implement appropriate interventions. While awaiting medical care, measures such as lying down to rest, deep breathing, or carotid sinus massage may help increase heart rate.
If the slow pulse is due to medication side effects, the drug should be discontinued and replaced under the guidance of a qualified physician to treat the condition. If bradycardia results from hypothyroidism, medications such as levothyroxine sodium tablets or thyroid extract tablets can be used to relieve symptoms.
