Cardiac arrhythmia

Cardiac arrhythmia is a situation in which a person experiences an unusual electrical activity in his heart. It is also known by other terms, including irregular heartbeat. In some cases, this situation is a medical emergency which can be fatal. Talk with a doctor for more information, or contact emergency medical professionals if there is an issue that may need to be dealt with. Additionally, keep in mind that although cardiac arrhythmias can be caused by hyperthyroidism, they may also be brought on by other medical reasons.


Not all cardiac arrhythmias cause medical symptoms. However, it is possible for things to be noticed in some cases. For instance, the item that is most frequently noted is heart palpitations -- that is, an abnormality in the person's heartbeat which leads to his awareness of that beat. This is not the same as simply noticing one's heartbeat when concentrating on it. On the contrary, palpitations typically get in the way of the person's thoughts.

Some cases of cardiac arrhythmias may lead to a decrease in blood pressure. This can cause additional symptoms, anywhere from a sensation of feeling lightheaded, to feeling dizzy, all the way to actually fainting. Once again, please talk with a physician or other professional about symptoms and other aspects of this situation. Do not use the details here as a replacement for professional advice.


A doctor or other professional in medicine is the one who offers a professionally-qualified diagnosis of cardiac arrhythmia. One way in which this is done is by using a stethoscope to listen to the heartbeat. Another option for diagnosis is by feeling the patient's peripheral pulses. Although these two methods typically do not lead to a diagnosis of any particular form of arrhythmia, they might show general items including whether or not the beat is regular, and how fast it is. An electrocardiogram can also be used. One other option is an electrophysiology test (EP test).


Different methods of management are used in certain instances where a patient has cardiac arrhythmia. For instance, one factor that is considered is whether the person is stable or unstable. Medications are used in some situations. Some of these are known as antiarrhythmics. However, other forms such as anticoagulants and those that slow the heart's conduction. Electricity is also used as a treatment option in some circumstances. Two particular forms of this are defibrillation and cardioversion. Other treatment methods are also used in some cases.
