heart beat irregularities are called a heart arrhythmia. Your heart beat is controlled by an electrical impulse that signals your heart to contract. This impulse begins in the sinoatrial node (SA node). This is the heart's natural pace maker. There are many factors that can attribute to heart arrhythmia from the condition of your heart: endocrine abnormalities, blood chemistry is abnormal, substance abuse or anxiety to name just a few. Most treatments are non-invasive or done on an out pt. basis. Many arrhythmia can be treated through radio frequency ablation which sends a radio signal to the cell muscles that are triggering the abnormal signal. The radio frequency destroys the cells that are causing the arrhythmia. There is a 90 percent success rate.
Either way, heart arrhythmia needs a doctor's intervention. It could be benign or a serious problem. Treatment options can vary but in the meantime, avoid all stimulants (caffeine smoking etc.), Lower salt intake, stay hydrated and try and reduce stress.
