What are the 4 classifications of syncope?
Syncope can be classified into four categories: reflex mediated, cardiac, orthostatic, and cerebrovascular. A cardiac cause of syncope is associated with significantly higher rates of morbidity and mortality than other causes.
What are the 2 types of syncope?
Reflex syncope is the most frequent cause of fainting. Vasovagal syncope — the common faint — occurs in one third of the population. It is by far the most common form of reflex syncope. Vasovagal syncope is often triggered by a combination of dehydration and upright posture.
What are the signs and symptoms of syncope?
The most common symptoms of syncope include:
- Blacking out.
- Feeling lightheaded.
- Falling for no reason.
- Feeling dizzy.
- Feeling drowsy or groggy.
- Fainting, especially after eating or exercising.
- Feeling unsteady or weak when standing.
- Changes in vision, such as seeing spots or having tunnel vision.
What is the most common cause of near syncope?
Vasovagal. This type of presyncope is caused by a drop in blood flow to your brain due to low blood pressure. This is the most common cause of syncope and presyncope. It’s usually caused by a combination of being dehydrated and standing or sitting up too quickly.
What is the proper treatment for syncope?
Cardiac pacing, implantable cardioverter‐defibrillators, and catheter ablation are the usual treatments of syncope caused by cardiac arrhythmias, depending on the mechanism of syncope.
Is syncope cardiac or neurological?
Syncope is a symptom, not a disease, and can be classified according to the underlying cause: neurological, metabolic, psychiatric, and cardiac7; cardiac syncope is the most common form.
What medications can cause syncope?
Drugs commonly implicated in syncope include the following: Agents that reduce blood pressure (eg, antihypertensive drugs, diuretics, nitrates) Agents that affect cardiac output (eg, beta blockers, digitalis, antiarrhythmics)
Can syncope be cured?
There is no standard treatment that can cure all causes and types of vasovagal syncope. Treatment is individualized based on the cause of your recurrent symptoms. Some clinical trials for vasovagal syncope have yielded disappointing results. If frequent fainting is affecting your quality of life, talk to your doctor.
What neurological conditions cause syncope?
3 There are only three neurological conditions that are likely to produce syncope:
- Transient ischemic attacks (TIA), usually involving the vertebrobasilar arteries.
- Subclavian steal syndrome.
- Normal pressure hydrocephalus (NPH)
