Palpitations are a sensation in the chest that is described in a number of ways. These include feeling a rapid heartbeat, a pounding in the chest, a fluttering of the heart, being conscious of the beating of the heart, or feeling missed or skipped beats of the heart.
Palpitations can be a symptom of a variety of mild to serious disorders, diseases or conditions. Palpitations can result from drugs use, infection, cardiac arrhythmia, myocardial infarction, trauma, and other abnormal processes.
Palpitations can occur in any age group or population. Palpitations are often associated with heart disease, but they can also occur with a wide variety of other diseases, disorders and conditions. For example, palpitations are commonly the result of the use of certain street drugs, such as methamphetamine and ecstasy.
Palpitations can also result from a relatively mild to moderate condition that is relatively easy to resolve, such as drinking too much coffee or an anxiety attack. Palpitations can also be a symptom of a serious or life-threatening condition, such as cardiac arrhythmia. Palpitations are commonly associated with a cardiac conditions, but any condition or disease that causes a rapid heart rate (tachycardia) can result in palpitations. These can include conditions of the respiratory system, the circulatory system, and the gastrointestinal system. For more details about causes, see causes of palpitations.
Depending on the cause, palpitations can be short-term and disappear quickly, such as when palpitations occurs during an anxiety attack. Palpitations can also occur in sudden, severe episodes, such as palpitations that happens with a cardiac arrhythmia called supraventricular tachycardia. Palpitations can also be chronic and ongoing over a long period of time, such as when it is due to a cardiac arrhythmia called chronic atrial fibrillation.
Palpitations often occur in conjunction with other symptoms, which vary depending on the underlying disease, disorder or condition. Other common symptoms include irregular pulse, chest pain, chest pressure, shortness of breath, cough, fever, abnormal vital signs, rapid breathing (tachypnea) and labored breathing (dyspnea). Dizziness, anxiety, restlessness and paranoia can also occur.
Complications of some underlying causes of palpitations can be life-threatening and include low oxygen levels and high carbon dioxide levels in the body, sepsis, shock, life-threatening cardiac arrhythmias, respiratory arrest, cardiac arrest and death.
Diagnosing palpitations and their root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination.
Depending on the suspected cause of palpitations, blood tests may include a complete blood count, which can reveal in infectious process, and cardiac assays, which can reveal a cardiac condition. Blood and urine drug screens can determine if there are any drugs in the body that may be the cause of palpitations.
An EKG and chest X-ray are also performed if the cause of palpitations is suspected to be due to heart disease or a respiratory disease. Continuous cardiac monitoring is also done to watch for cardiac arrhythmias, which are a common cause of palpitations.
An exam also includes listening with a stethoscope to the sounds that the heart and lungs make. Certain types of heart sounds, such as a heart murmur, point to some underlying causes of palpitations, such as mitral valve prolapse. Certain lung sounds point to some underlying causes of palpitations. For example, a bubbling sound may point to congestive heart failure.
Other important tests include a noninvasive test called a pulse oximetry is generally performed. This involves clipping a painless device to the fingertip, which can measure the amount of oxygen in the blood.
Depending on the suspected cause of palpitations, other tests can include additional blood tests, culture and sensitivity tests, pulmonary function test, and imaging tests, such as CT scan, nuclear scans, and MRI.
A diagnosis of palpitations and its cause can easily be delayed or missed because palpitations may be mild or vague and for other reasons. For information on misdiagnosis, refer to misdiagnosis of palpitations.
Treatment of palpitations involves diagnosing and treating the underlying disease, disorder or condition that is causing them. Some conditions can be easily and successfully treated and cured, while others may require more intensive treatment and may not have an optimal prognosis.

Article Excerpts about Palpitations
"Extra" heartbeats, also called palpitations, or premature
ventricular contractions (PVCs) happen when there is irritation in the
lower part of the heartís pumping chambers. PVCs interrupt the normal
heart rhythm and cause an irregular beat that can feel like a "missed
beat" or a "flip-flop" in the chest. This can be harmless or it may lead
to problems that are more serious. (Source: excerpt from HEART AND CARDIOVASCULAR DISEASE: NWHIC)
