Synopsis

Do you know a normal heartbeat with a speed between 60 and 100 bpm while resting? Whereas patients suffering from bradycardia will have a heart rate slower than usual, this medical condition is effectively treatable, whereas diagnosing and treating at the right time is essential. 

Key Takeaways

  • Some healthy individuals like Athletes have lower than normal heart rates
  • It is normal to drop your heartbeat while sleeping
  • The progress in the medical industry raised the scope of bradycardia treatment

Heart rate signifies how healthy your heart is. It is measured by the number of times your heartbeat is in one minute. As already said, having 60-100 bpm while resting comes under the healthy heart range. However, trained athletes may have a lower heart range because of a strong heart; extra hard work is not needed to pump blood throughout the body. In certain cases, bradycardia may turn out to be serious if the heart rate becomes too slow to pump enough oxygen-rich blood to meet the body’s needs. There are also chances that this medical -condition occurs and shows no harmful effects if the person is physically fit & active. The term bradycardia comes from the Greek words Bradys and Kardia, which together mean slow heart. 

There are several causes of bradycardia, and in some cases, symptoms are not visible. However, it is also good to be aware of the situation. Read further about bradycardia symptoms, bradycardia treatment, and causes.

What are the symptoms of bradycardia? 

A slower heart rate means enough oxygen-rich blood is not reaching the orangs & tissues of the body. This can affect the heart and brain systems. Due to this, the body may find it hard to process normal functions. In some cases, symptoms may be mild or not much noticeable. The common bradycardia symptoms include: 

  • Chest pain 
  • Weakness 
  • Shortness of Breath 
  • Fatigue 
  • Memory-related problems, confusion 
  • Lack of concentration 
  • Fainting, dizziness, Lightheadedness 
  • Getting easily tired during physical activity 
  • Heart Palpitations 
  • Irritability 
  • Agitation 

If you notice any of the symptoms happening frequently, it’s good to take the doctor’s advice.

What are the causes of bradycardia? 

The treatment of bradycardia tends to be easier after realizing the causes of bradycardia. Here are a few reasons for this medical state:

  • Deficiency in electrolytes

Electrolytes such as potassium, calcium & magnesium influence cardiovascular functions. The imbalance of these electrolytes can affect the heart rate. 

  • Bacteria

Bacteria from certain infections can cause heart damage, especially to heart valves.  

  • Myocarditis

Inflammation of the heart muscle occurs due to infection or autoimmune disorder. This condition reduces the heart’s ability to pump blood. 

  • Anorexia Nervosa

An eating disorder where the patient suffers from an intense fear of gaining weight leads to abnormally low body weight. This health condition is associated with bradycardia.  

  • Congenital heart disorder

The abnormalities in the working condition of the heart by birth. While repairing congenital heart disorders or valve replacement, there is a risk of causing bradycardia. 

  • Hypothyroidism

Thyroid hormones help to control heart rate. The underactive thyroid gland produces fewer hormones which affect the heart rate. 

  • Sleep apnea

Interrupted sleep pattern has the potential to contribute to this condition. 

  • Rheumatic fever

Rheumatic fever caused due to bacterial infection can lead to bradycardia after the first attack. 

  • Block in heart

Interruption in the flow of the heart’s electric current; the electrical signals follow the irregular pattern of flow from the upper chamber to the lower chamber. The complications of heart block are divided into three degrees. 

  • Inflammation

Inflammation occurs to the heart’s inner lining, endocarditis, heart muscle, or pericardial sac and may promote bradycardia.

Bradycardia

Side effects from certain medicines 

  • Beta-blockers- Prescribed to control blood pressure 
  • Calcium channel blockers 
  • Narcotic medications 
  • Antiarrhythmic drugs 
  • Recreational drugs (marijuana)

Sick sinus node syndrome 

Before understanding the sinus node, let us get an idea of the heart structure. A heart has four chambers, two upper chambers called atria and lower chambers called ventricles. In the upper right chamber of the heart, there is a group of cells referred to as the sinus node. It is called a natural pacemaker of the heart. It initializes the signals that produce a heartbeat.  

Sick sinus node syndrome [1] affects the sinus node and disrupts heart rhythm. People suffering from sick sinus may experience slow heartbeat and alternation of heart rhythm, hence becoming one of the causes of bradycardia.

How to diagnose bradycardia? 

Health care providers undergo physical examination & laboratory tests to confirm bradycardia. The tests include:

  • Electrolyte test to measure potassium, calcium, magnesium 
  • Other laboratory tests include a test to check thyroid hormone levels & troponin. 
  • Toxicology screening to identify drugs  
  • Sleep study to understand sleep pattern  
  • An echocardiogram diagnoses a heart condition and uses sound waves to create images of the heart. 
  • Health care providers also conduct a physical examination to measure vital signs, including heart rate, blood pressure & respiratory rate. 
  • Electrocardiogram (ECG or EKG) – It is an important test to detect bradycardia because it gives a precise report of the heart’s electrical activity.

Which medication is needed to treat bradycardia? 

In the early stages of bradycardia, the doctor may not suggest treatment depending on the cause. If the slow heart rate is a side effect of a drug doctor may replace the medicines. 

Medicines 

These are the few medicines used to treat bradycardia only in difficult situations where symptoms are acute. This medicine helps to increase heart rate. 

  • atropine 
  • dopamine 
  • epinephrine 
  • glycopyrrolate 

This medication is injected via intravenous infusion.

Temporary cardiac pacing 

It is an effective short-term treatment for those who need a pacemaker or whose bradycardia will likely be short-lived. In this treatment, a device with electrical contact is used to provide a mild electrical current to stimulate the heartbeat. 

Permanent pacemaker 

For some people, a permanent pacemaker is the best solution, especially if the patients are suffering from sick sinus node syndrome, where your heart’s natural pacemaker cells are unable to initiate electric signals properly. In this bradycardia treatment, a device is implanted via surgery to maintain the heart rhythm. Most pacemakers last for years, and if it relies on the battery, it continues for decades.

How to prevent bradycardia? 

Even though it is not preventable, here are a few natural ways promoted by a health care provider to reduce the chances of bradycardia. 

Healthy diet

A healthy life starts from a healthy diet. Try to include a Heart Healthy Diet in your diet chart. Food with low fats, low sugar, vegetables, whole grains, and dairy products are good for the heart. Apples, Avocados, and Berries are favorable fruits for the heart. 

Exercising

Physical activity is essential for body fitness. You can include a 10-minute walk and morning jogging in your daily schedule. If you are a gym person, seek expert advice on a heavy workout.  

Alcohol

Avoid too much drinking. It’s okay to have drinks in one or two months but if you think it’s going above the top, press the pause button immediately. If you cannot control the habit, take a doctor’s help. 

Body weight

Increasing body weight enhances the risk of heart disease, but it doesn’t mean starving to reduce weight. Try to have a healthy diet in the required quantity with other routines like exercise, yoga, or gym. 

Stress

Emotional imbalance can affect the heart at an immense level. Manage your stress with the help of relieving techniques like meditation, happy clubs, and support groups. 

Check-up

Treatment at early stages increases the chances of a cure. If possible, try to have a periodical check-up to know your blood glucose level, bp & tests for Healthy Heart. 

Use of recreational drugs

These drugs are not consumed for medical reasons. Avoid the usage of this kind of drug, and remember self-medication is harmful; if you notice any kind of uneasiness after having this substance, meet the doctor without fail.

How long can it stay? 

It can be a life-long problem or live for a short period. In most cases, it stays for a short time due to certain drugs. However, the cause decides the duration of the disease. Other than medicines & treatment, you can put efforts from your end by maintaining a healthy lifestyle, avoiding unnecessary stress & most importantly, accepting the health condition & try to build a positive mindset [2]. Easier said than done, but doctors have suggested a patients-mindset effect for faster recovery and well-being.
