Sinus Bradycardia and Receiving Social Security Disability BenefitsSinus Bradycardia is another form of cardiac arrhythmia and is classified as a cardiovascular disorder. Cardiac arrhythmia is a medical term that is used to refer to any of a group of conditions in which the electrical activity of your heart is irregular, or it is slower or faster than what is considered to be normal. Some types of cardiac arrhythmias are minor and can even be viewed as being normal. Other cardiac arrhythmias are serious, life-threatening medical emergencies that may result in cardiac arrest and sudden death. Tachycardia is a cardiac arrhythmia in which your heart rate is too fast. In adults, this usually means a heart rate that is greater than 100 beats a minute. Bradycardia is the medical term that is used in reference to a cardiac arrhythmia in which your heart is beating too slow. Usually, in adults, bradycardia is used when your resting heart rate is below 50 to 60 beats a minute. However, it needs to be pointed out that a resting heart rate below 50 to 60 beats a minute does not always mean that you have bradycardia. Athletes may have a resting heart rate that is below 50. The term relative bradycardia is used sometimes for a heart rate that is not below 60 beats a minute. It is used when your heart rate is believed to be too slow for your current medical condition. Bradycardia may take place in three basic sites. They are the sinus node, autonomic nervous system or conduction system. Sinus bradycardia is bradycardia that arises from your sinus node. Your sinus node is the natural pacemaker of your heart that is located in the right atrium of your heart. Sinus bradycardia can be a good thing. Sinus bradycardia may be an indication of good health. As mentioned earlier, many athletes have this condition due to having a healthy heart. Sinus bradycardia may develop as a result of rigorous conditioning that comes from physical exercise. This can cause your heart to beat at a steady pace.
