Syncope is a medical term used to describe a sudden temporary loss of consciousness or fainting. It is caused by a temporary decrease in blood flow to the brain.
Cardiac syncope is a type of syncope that is caused by a problem with the heart. It can be caused by a variety of conditions, including arrhythmias, heart valve problems, and coronary artery disease.
Features of cardiac syncope can include a rapid or slow heartbeat, chest pain, shortness of breath, and palpitations. It may also be accompanied by other symptoms, such as lightheadedness, dizziness, and nausea.
Diagnosis of cardiac syncope may involve a variety of tests, including an electrocardiogram (ECG), echocardiogram, stress test, and cardiac catheterization.
Cardiac syncope is relatively rare, but it can be a serious condition if left untreated. Treatment may involve medications to control heart rate or blood pressure, or procedures such as a pacemaker or defibrillator to correct abnormal heart rhythms.
Prevention of cardiac syncope may involve managing underlying medical conditions, such as high blood pressure or diabetes, and taking steps to reduce the risk of heart problems, such as maintaining a healthy diet and exercise routine and not smoking. It is important to see a doctor if you experience syncope or other symptoms of a heart problem.
