Causes of Syncope

Syncope, also known as fainting, is usually a sign of there being problems with the heart. It is not considered to be syncope if you experience dizziness due to problems with your ears or your nerves. However, if you have dizziness or fainting being caused from a heart disease, it is considered syncope.

There are various types of heart diseases that a cardiologist in Texas City or another Houston area city can diagnose and treat. Some diseases that cause syncope include:

  • Transient Ischemic Attacks or a mini stroke
  • Orthostatic Hypotension, or when a person feels faint after standing up too quickly
  • Cardiac Arrhythmia, or when a person’s heart beats too fast, too slow, or irregularly

What is Cardiac Arrhythmia

If your doctor has diagnosed you with cardiac arrhythmia, they may refer you to a heart doctor in the area to develop a treatment. A normal heartbeat is enabled by the heart’s electrical system so the heart’s pumping action, or beats, occur regularly. Cardiac arrhythmia is when the electrical system is not working properly and the heart does not beat regularly.

If your heart is unable to pump enough blood to the brain, you may experience syncope, dizziness, or confusion. Effects of cardiac arrhythmias can be either life-threatening or harmless but no matter what it is important to speak with a cardiologist to be treated for this condition.

Orthostatic Hypotension and Syncope

Almost everyone has experienced orthostatic hypotension at one point or another. If you stand up from a sitting position too quickly, it may cause an abrupt change in blood pressure due to the blood moving against the arteries’ inner walls as it flows through them. Blood also pools in the legs due to gravity which can cause dizziness. Dizziness from orthostatic hypotension may progress into syncope or cause confusion.

Transient Ischemic Attacks and Syncope

More commonly known as a mini stroke, transient ischemic attacks occur when blood flow to the brain is dramatically low or interrupted, which causes brain cells to die after a couple of minutes. Transient ischemic attacks produce stroke-like symptoms due to a temporarily clogged artery that is supplying blood to a part of the brain. This oxygen and blood deprivation may result in various symptoms, including syncope. Fortunately, these types of attacks do not last for a long time nor cause lasting damage to the brain compared to a full blown stroke.
