A slow heartbeat is a type of arrhythmia that usually refers to a heart rate lower than the normal range, which means the heart beats less than 60 times per minute. A normal person's heart rate is usually between 60 and 100 minutes, but some people may have a heart rate below 60 minutes. The slow heartbeat may be due to a problem with the heart itself or other underlying conditions.
The heart plays the role of pumping blood, sending oxygen and nutrients to all organs throughout the body. A slow heartbeat causes the heart to pump less efficiently, which can lead to various health problems. When the heart is unable to efficiently pump blood throughout the body, people may experience symptoms such as fatigue easily, shortness of breath, dizziness, and poor physical strength. Therefore, a slow heartbeat sometimes requires the necessary **.
There are a variety of causes of slow heartbeat. Some people are born with a slower heart rate, which is known as "sinus node dysfunction." In addition, certain diseases, medications, or surgeries can cause heart rhythm disorders, which can slow down the heart rate. Below we will detail some of the common slow heartbeats.
First, sick sinus syndrome. It is a condition associated with sinus node dysfunction. Under normal circumstances, the sinus node is the heart's pacemaker, and it sends out electrical signals that trigger the heart to contract. However, people with sick sinus syndrome have impaired sinus node function and are unable to pace properly, resulting in a slowed heart rate.
Second, the effects of drugs. Certain medications, such as receptor blockers and calcium antagonists, may affect the heart's conduction system, slowing the heart rate. These medications are commonly used for conditions such as high blood pressure, arrhythmias, etc., but in some people they can cause a slower heartbeat.
Third, viral myocarditis. This is an inflammation of the heart caused by a viral infection. Viral infections can cause damage to the heart muscle, affecting the normal function of the heart, including the heartbeat. Slow heartbeat is often a pathologic manifestation of viral myocarditis.
Fourth, after heart surgery. Certain heart surgeries, such as artificial heart valve implants, can cause damage to the heart's conduction system, which can affect the normal heart rhythm and slow the heart rate.
A slow heartbeat may not cause major health problems in some cases. For example, it is normal for some older people, athletes with a high level of physical activity, or patients undergoing cardiac repair surgery to have a slightly lower heart rate. However, in some young or healthy people, further evaluation and** may be required if the heart rate is too low.
*The method of slow heartbeat depends on the specific cause of the slowed heart rate. If sick sinus syndrome is the main cause, your doctor may recommend a pacemaker implant to help maintain a normal heartbeat. Medications** are also a common way to correct abnormal heart rhythms by taking medications that increase your heart rate. December Creation Incentive Program
