Is a Pulse Rate Below 60 Normal?
How many times per minute is the pulse rate? This is also a common examination method used by doctors. Normal pulse rates vary among different age groups, but if it falls below 60 times per minute, it is definitely abnormal. There are many reasons for a lower pulse rate, which are usually related to cardiovascular diseases. If this condition persists for a long time, it is essential to promptly consult a doctor to understand the specific reasons and avoid further harm to physical health.
Is a pulse rate below 60 times per minute normal?
If the pulse rate is below 60 times per minute, it is considered bradycardia, which can be classified as pathological or physiological. While a pulse rate below 60 for athletes can be considered normal, it can cause symptoms such as chest tightness and difficulty breathing in ordinary individuals. In such cases, it is advisable to seek medical attention.
What causes bradycardia?
1. Generally speaking, conduction block can cause the heart to beat at a frequency lower than the normal range due to lesions in the atrium and myocardium.
2. Changes in vagal nerve tension can also lead to bradycardia. When the vagal nerve is excited, it may release a substance called acetylcholine, which has an inhibitory effect on heartbeats, thus slowing down the heart rate.
3. Changes in the function of the sinus node can also lead to bradycardia. If bradycardia is caused by changes in the function of the sinus node, the heart rate will be approximately 40 times per minute.
4. Stimulation by certain drugs can also lead to tachycardia. For example, epinephrine, atropine, caffeine, thyroxine, and other medications can all cause tachycardia. Additionally, smoking, drinking, and drinking tea can also contribute to tachycardia in some individuals.
5. Individuals with systemic diseases, such as beriberi, acute rheumatic fever, or hyperthyroidism, may also experience tachycardia in their daily lives.
