Experiencing a sudden loss of consciousness or a near-fainting spell can be a frightening event. In the medical field, this is known as syncope. While many people may dismiss feeling faint as a minor consequence of dehydration or heat, it can often be a warning sign of a heart rhythm disorder. At Mobitz Heart Rhythm Clinic, Dr. Alireza Nazeri provides specialized diagnostic and treatment plans for patients across Greater Heights, University Place, and the Galleria, TX, area who are struggling with these episodes.
Recognizing the Warning Signs
Fainting occurs when there is a temporary drop in the amount of blood flowing to the brain. Before a person actually loses consciousness or feels like they might black out, they often experience several "pre-syncope" symptoms. These may include:
- Feeling dizzy or unsteady on your feet.
- Experiencing a sudden sensation of being lightheaded.
- Blurred or "tunnel" vision.
- Nausea or a sudden cold sweat.
It is important to distinguish syncope from vertigo. While syncope relates to a lack of blood flow and a feeling of passing out, vertigo is specifically a sensation of spinning or movement when you are actually still. If you are experiencing a true loss of consciousness, a cardiac evaluation is essential.
Why Cardiac Electrophysiology Matters
As a Cardiac Electrophysiologist, Dr. Nazeri focuses on the "electrical system" of the heart. Many cases of syncope are caused by arrhythmias, conditions where the heart beats too fast (tachycardia) or too slow (bradycardia). When the heart rhythm is irregular, it cannot pump blood efficiently to the brain, causing the patient to collapse.
Common cardiac causes of fainting include:
- Vasovagal Syncope: A sudden drop in heart rate and blood pressure, often triggered by stress or standing too long.
- Carotid Sinus Syndrome: Hypersensitivity in the neck arteries.
- Heart Block: A disruption in the electrical signals that coordinate your heartbeat.
Comprehensive Diagnostics and Treatment
At Greater Heights, University Place, and the Galleria, TX’s Mobitz Heart Rhythm Clinic, we utilize advanced technology to get to the bottom of why you are feeling faint. Our diagnostic process may include:
- Holter or Event Monitoring: Portable devices that record your heart rhythm over several days.
- Tilt Table Testing: To observe how your heart rate and blood pressure respond to changes in position.
- Implantable Loop Recorders: Small sensors placed under the skin to capture data over a long period.
Once a diagnosis is reached, Dr. Nazeri develops a personalized plan, which may include lifestyle adjustments, medication, or the placement of a pacemaker or ICD, to prevent future episodes and protect your long-term health.
