![]() ![]() Medications to control irregular heart rhythms or underlying disease.Treatment for a rapid heartbeat (tachycardia) depends on whether it occurs in the upper chambers (atria) or lower chambers (ventricles) of the heart.It delivers an electrical impulse to stimulate (pace) the heart's muscle contractions if the heart rate drops below a certain number of beats per minute. The pacemaker continuously monitors the heart's natural rhythm. Insertion of a pacemaker is the standard treatment for syncope caused by a slow heartbeat (bradycardia).Simple reassurance, proper hydration, anticipatory guidance, safety precautions, and increased salt intake are helpful for common type fainting (vasovagal syncope) especially in children and young adults.Treatment should address the underlying cause of syncope.ĭepending on the diagnosis, cardiovascular syncope may be stopped or controlled with one or more of the following therapies: When it comes to treatment, there is no "one size fits all" approach, making an accurate diagnosis very important. Syncope is a symptom that can be caused by many different factors. Channellopathies (defects of the electrical system of the heart) like Long QT syndrome and Brugada Syndrome.Some congenital heart defects or syndromes (like William's syndrome).Fainting during exertional activity or exercise.Recurrent episodes of fainting that come on suddenly and without warning.An abnormal electrocardiogram (a common test to check for abnormal heart rhythms).Cardiomyopathy (structural problems with the heart's muscles).Ventricular dysfunction (weakness in the heart's pumping chambers).Prior heart attack (myocardial infarction).Chest pain caused by angina (lower blood supply to the heart).Coronary artery disease (clogged blood vessels to the heart).Those at greatest risk are people who have any of the following conditions: The risk of cardiovascular syncope increases with age. People with underlying heart disease are at higher risk for cardiovascular syncope, although this may be the initial symptom suggesting such a problem. They may occur even in young, otherwise healthy people with normal heart function. This type of syncopy is often related to problems with the autonomic nervous system (ANS), which controls functions such as heart rate and blood pressure. ![]() There are a variety of causes not necessarily related to the heart. Non-cardiovascular syncope - The most common type (also called vasovagal type). There are two types of syncope (fainting) to watch out for:Ĭardiovascular syncope - The most dangerous but rare type of fainting is caused by an abnormal heart rhythm (arrhythmia) or by structural damage to the heart. In some cases, fainting is the only warning sign of an abnormal heart rhythm (arrhythmia) that could lead to sudden cardiac arrest and death. The most serious causes of syncope are related to heart damage or abnormal electrical system disorders that affect the heart's ability to pump blood efficiently. However, some are life threatening, especially fainting during exertion. Many causes of syncope, however, are not easy to explain and are not serious. Profound blood loss or fluid loss (severe diarrhea or vomiting) may also cause syncope. It may be explained by factors such as stress, grief, overheating, dehydration, painful stimuli, exhaustion, or illness. Fainting is common and a single spell usually is not serious. Typically, a fainting spell lasts only a few seconds or minutes, and then the person regains consciousness. It most often happens when the blood pressure is too low (hypotension) and the heart does not pump enough oxygen to the brain. Fainting (syncope) is a sudden transient loss of consciousness. ![]()
