Cardiogenic syncope is a case of fainting due to cardiovascular problems. This is one of the most serious forms of syncope. Patients may have symptoms similar to a heart attack, such as tightness in the chest, shortness of breath or palpitations. Cchocardiograms, electrocardiograms and exercise stress tests can be used in diagnosis.
Vasovagal reflex syncope results from intermittent dysfunction of the autonomic nervous system, causing symptoms, including: headedness, dizziness, and nausea. A tilt table test, an implantable loop recorder and an EEG is usually used in diagnosis. People with a single, isolated episode of vasovagal syncope generally do not require any medical therapy. Otherwise, medications may be recommended.
Orthostatic hypotension is a form of low blood pressure that happens when you stand up from sitting or lying down. Symptoms include feeling lightheaded or dizzy after standing up, blurry vision and fainting. Blood pressure monitoring, blood tests and ECG are usually recommended in diagnosis. Treatment aims at restoring normal blood pressure.
