One of the symptoms of thyroid problems, in particular of hyperthyroidism, is heart palpitations. In this situation, there is an abnormality of the person's heartbeat, and he is aware of its beat. That doesn't mean that it has any particular difference, though. For instance, it could be quicker, or slower, than normal. It might have its regular frequency, or be irregular. It is not the same as a normal awareness of a heartbeat which may happen when one concentrates on that beat.
Heart palpitations themselves are a kind of symptom. The individual who is having them might not notice any other medical issues. However, it can be linked with other symptoms. For instance, shortness of breath, sometimes known as dyspnea, might also occur. The individual may become light-headed or dizzy. Chest tightness may also be present. If the person has a blackout, or gets close to one, then it may point to heart disease being behind the situation.
There are various types of palpitations, and within those particular medical causes are possible. Hyperthyroidism is a cause of what fits into the hyperdynamic circulation classification. Anemia and fever are a couple of other causes of this type. Other palpitation types can be brought on by various causes, for instance, low levels of blood glucose, heart failure, and premature atrial contraction. If a person is anxious, it may impact his heart muscles in a way that leads to this condition.
A qualified diagnosis of this issue is made by a medical professional, such as your doctor. At the start, the foremost piece of evidence that is considered may be how the individual describes what he is feeling (that is, the palpitations). Things such as the situation surrounding their occurence, and the age at which the person began to be aware of them might also be considered. An ECG is not typically used for diagnosis, but changes in it may be useful, and it is still frequently used, particularly in assessing the condition. Thyroid function and other tests using blood may be administered.
