When you have a heart rate that is slower than normal, then this is called Bradycardia. Normally, the heart will beat somewhere between 60-100 times every minute. This is for an adult that is resting. Someone that has bradycardia has a heartbeat of less than 60 beats a minute.

If someone’s heart isn’t pumping enough blood that is rich in oxygen, this can be a serious problem. The individual could possibly need a pace maker implanted in them or possibly another treatment to help them maintain the proper heart beat.Having a proper heart rate is certainly a must. If it is too high or too low of a heart rate, then there could be serious problems.

If you realize that your heart isn’t beating properly, then make sure you see a medical professional right away. Some may have a different heart rate because of size or genetics, but it is so important that you get this checked. It could very well be serious.

Don’t hesitate to see a professional if you are curious to why your heart rate isn’t what it should be, whether it is high or low. If you exercise, then it will usually pull your heart rate lower because the stronger the heart, the less it has to pump to get the blood to where it needs to go. But this doesn’t mean that you should avoid medical help if you have a low heart rate and exercise regularly.

The cause of sinus bradycardia is usually something disrupting the person’s regular electrical impulses that control the pumping action of the heart. There are many things that can be the contributing factor of this, or the direct problem. These are:

  1. Heart tissue that is damaged because of aging.
  2. Damaged heart tissues due to heart disease or attack
  3. Blood pressure that is high
  4. A congenital heart defect
  5. Heart tissue that has an infection
  6. Heart surgery complications
  7. A thyroid gland that is underactive
  8. If your electrolytes are imbalanced
  9. Sleep Apnea
  10. Diseases that are inflammatory, such as lupus
  11. Iron buildup in the organs
  12. Different medications including those for high blood pressure

The heart has 4 chambers. There are two lower and two upper chambers. These are called the atria and the ventricles. Your heart has a natural pacemaker, called the sinus node. This is in the right atrium of the heart. It will produce electrical impulses that will cause each of your heartbeats.

 

Starting with the sinus node, an electrical impulse will travel across your atria, and this causes it to pump blood into your ventricles because it makes your heart contract. Once the electrical impulses arrive at the atrioventricular node, it will transmit a signal to what is called “the bundle of his,” which is a special collection of cells. These will send the signal down the left ventricle and the right ventricle.

Once the impulse goes down those branches, the ventricles will pump the blood by causing contractions. This will send oxygen rich blood into the body and the oxygen poor blood will end up going to the lungs. Sinus Bradycardia will occur when these signals are blocked or end up slowing down.

Sinus Bradycardia usually will get started in the sinus nodes. The heart rate may slow down due to the sinus node sending a slower rate of electrical impulses, if it fails to discharge at the rate it should, or the electrical impulses are blocked, thereby making the atria contract. This problem can result in a person’s heart rate alternating between fast and slow heart beats. When this happens it will make a person panic and very uneasy.

As you can see, sinus bradycardia isn’t a good thing to have. It slows down the heart, and usually is caused by something not working the way it should. If this is happening with you, it would be good to seek a doctor as soon as possible. You don’t want to wait and risk further problems down the road.
