Syncope & Loss of Consciousness in Children — Phoenix, AZ

Syncope (fainting) and loss of consciousness in children require careful evaluation to distinguish benign causes from serious cardiac or neurological conditions. Dr. Tamara Zach MD at Rose Medical Pavilion provides systematic evaluation for children throughout Phoenix, AZ.

Common Causes of Syncope in Children

The most common cause of childhood syncope is vasovagal syncope — a benign reflex response to triggers such as prolonged standing, heat, dehydration, pain, or emotional stress. Arizona's extreme heat significantly increases syncope risk, particularly during summer months when children are active outdoors.

When to Be Concerned

Red flags requiring urgent evaluation include syncope during exercise, syncope without warning, syncope with family history of sudden cardiac death, chest pain or palpitations before loss of consciousness, and syncope associated with neurological symptoms such as prolonged confusion, focal weakness, or abnormal movements.

Distinguishing Syncope from Seizure

This distinction is clinically important and can be challenging. Syncope typically involves a brief period of pallor, sweating, and lightheadedness before loss of consciousness. Brief convulsive movements can occur with syncope and do not always indicate a seizure. Dr. Tamara Zach MD performs EEG and detailed history to clarify the diagnosis when needed.

Evaluation and Management

Evaluation includes neurological examination, EEG when seizure is suspected, ECG, and coordination with cardiology for exercise-triggered or high-risk syncope. Most children with vasovagal syncope respond well to increased salt and fluid intake, positional maneuvers, and avoidance of triggers.
