A SUDDEN, TEMPORARY LOSS OF CONSCIOUSNESS
Syncope
A sudden temporary loss of consciousness from reduced blood flow to the brain, often called fainting. Most cases are benign, but cardiac causes need urgent evaluation and treatment.
ABOUT THIS CONDITION
What is Syncope
Syncope is a sudden, temporary loss of consciousness caused by a brief reduction in blood flow to the brain. It is typically followed by a rapid, complete recovery. Common types include vasovagal syncope (the simple faint, often triggered by standing, heat, pain or strong emotion), orthostatic syncope (on standing up due to a drop in blood pressure) and cardiac syncope (due to arrhythmias or structural heart problems). Some episodes are benign, while others — particularly cardiac syncope — can be warning signs of serious heart disease. Important features include syncope during exertion, sudden onset without warning, syncope in a patient with known heart disease or family history of sudden death, and episodes associated with palpitations or chest pain. Evaluation includes ECG, echocardiography, BP measurements, blood tests and longer-term rhythm monitoring or tilt testing in selected cases. Dr. Patnam Pravallika Reddy provides comprehensive evaluation and care of syncope at Lux Hospitals, Hyderabad.

Symptoms that need attention
WHY IT HAPPENS
Causes & Risk Factors
- Vasovagal — sudden reflex drop in heart rate and BP
- Orthostatic hypotension on standing up
- Dehydration and reduced fluid intake
- Cardiac arrhythmias — fast or slow rhythms
- Structural heart disease such as valvular conditions
- Certain medications causing BP drops
- Neurological conditions in some patients
- Severe anaemia and metabolic causes

HOW WE TREAT IT
Treatment Approach
Detailed Evaluation with Targeted Management
The most effective approach is a detailed evaluation to identify the cause — combining history, ECG, echocardiography, BP monitoring and rhythm studies — followed by targeted management of the underlying condition, with cardiology input for suspected cardiac causes.
- 1
Consultation & Assessment
Dr. Pravallika reviews the circumstances of the episode, examines you, measures lying and standing BP and orders ECG, blood tests and echocardiography.
- 2
Treatment Planning
A personalised plan is created based on the most likely cause, with further rhythm monitoring or specialist referral where needed.
- 3
Medical Management
Hydration and postural advice, treatment of underlying conditions, review of medications and management of any arrhythmias or structural heart problems.
- 4
Recovery & Follow-up
Follow-up review to confirm response, address recurrent episodes and advise on lifestyle and safety, including driving where relevant.
AVAILABLE TREATMENTS
Treatment Options
Identification of Cause (Cardiac, Neurological, Vasovagal)
Care begins with careful identification of the underlying cause, which guides all further management.
Hydration and Dietary Advice
Adequate fluid and salt intake helps reduce the risk of vasovagal and orthostatic syncope in suitable patients.
Postural Maneuvers
Specific maneuvers and gradual postural changes help prevent fainting in patients with orthostatic or vasovagal syncope.
Treating Underlying Condition
Specific treatment is given for arrhythmias, structural heart disease, anaemia, dehydration or medications causing syncope.
ECG and Cardiac Evaluation
ECG, echocardiography and longer-term rhythm monitoring evaluate for cardiac causes and guide management.
