Tachycardia refers to a heart rate that is elevated beyond its normal level. It can be thought of as a rapid heart rate. Although it can be caused by many different things, some of the possibilities include thyroid problems. For instance, thyroid storm, Hashimoto's thyroiditis, and Graves' disease all might cause a person to experience tachycardia.
The number of heart beats per minute which is considered to be tachycardia varies based upon age. Let's take, as an example, an adult (considered in this circumstance to be someone greater than 15 years old). For a person of that age, any bpm above 100 is considered as a high rate. However, for a 4-year-old, the number would be anything beyond 137 bpm. In an infant who was 2 months of age, that level would become anything above 179. A newborn who was 1 day old would be considered as having tachycardia if his heart rate were beyond 159 bpm. Something to consider is that these figures refer to the rate when a person is sleeping or otherwise inactive. They are not necessarily useful for comparison if a person had just participated in a marathon.
Tachycardia can be categorized into different groups. For instance, in one way, there are both narrow and wide complex forms. Within the narrow, there are particular types, such as sinus tachycardia, atrial flutter, atrial fibrillation, and others. Hyperthyroidism has the potential to lead to, at least, the sinus variety, although even in this case there are numerous other possible medical causes. As a wide complex form, ventricular tachycardia is the label for a type that has its beginning in the patient's ventricles.
Please talk with a doctor regarding treatment for tachycardia, rather than using the information supplied here. These details are not professional in nature nor are they meant to take the place of information or assistance that is. In general, aspects about the tachycardia are used in determining the method of treatment. For instance, its classification as either wide or narrow is taken into consideration. Whether the patient is stable or not is another aspect, and something somewhat related to that which is also considered is whether the instability (if that is the case) is due to the tachycardia itself.
