Near-Syncope (नीयर-सिंकॉप) को अक्सर “लगभग बेहोशी” कहा जाता है।
- यह एक transient event है जिसमें बेहोशी (syncope) तो नहीं होती, लेकिन व्यक्ति को गिरने या खोने का अनुभव होता है।
- अक्सर lightheadedness, dizziness, या weakness के साथ होता है।
- यह heart, neurological या metabolic disorders का संकेत हो सकता है।
Near-syncope, syncope के precursor के रूप में देखा जा सकता है।
Near-Syncope क्या है (What is Near-Syncope)
- Feeling of faintness, almost losing consciousness
- व्यक्ति आमतौर पर alert रहता है और full loss of consciousness नहीं होता
- Associated symptoms: sweating, nausea, palpitations, blurred vision
- Often triggered by standing up quickly, dehydration, or cardiac arrhythmias
Near-Syncope कारण (Causes of Near-Syncope)
1. Cardiac Causes
- Arrhythmias (ventricular tachycardia, atrial fibrillation)
- Structural heart disease (aortic stenosis, hypertrophic cardiomyopathy)
- Myocardial infarction
2. Neurogenic / Vasovagal Causes
- Vasovagal syncope – emotional stress, pain, prolonged standing
- Orthostatic hypotension – sudden drop in BP on standing
- Carotid sinus hypersensitivity
3. Metabolic / Systemic Causes
- Hypoglycemia (low blood sugar)
- Anemia (low hemoglobin)
- Dehydration or electrolyte imbalance
4. Medications
- Antihypertensives
- Diuretics
- Vasodilators
- Antiarrhythmic drugs
5. Neurological Causes
- Seizures (atypical presentation)
- Transient ischemic attack (TIA)
Near-Syncope लक्षण (Symptoms of Near-Syncope)
- Lightheadedness or dizziness
- Feeling of fainting or blacking out
- Blurred vision or tunnel vision
- Palpitations or irregular heartbeat
- Sweating, nausea, or pallor
- Weakness in legs, imbalance while standing
Symptoms usually resolve quickly once person lies down or sits।
Near-Syncope कैसे पहचाने (Diagnosis of Near-Syncope)
- Medical History – triggers, duration, associated symptoms, medications
- Physical Examination – blood pressure (lying, sitting, standing), heart rate, neurological exam
- Electrocardiogram (ECG) – detect arrhythmias
- Echocardiography – structural heart disease
- Holter Monitor – for intermittent arrhythmias
- Blood Tests – glucose, electrolytes, hemoglobin
- Tilt Table Test – evaluate orthostatic hypotension or vasovagal syncope
Accurate diagnosis essential to prevent progression to full syncope or cardiac events।
Near-Syncope इलाज (Treatment of Near-Syncope)
1. Immediate Measures
- Sit or lie down to prevent injury
- Elevate legs to improve blood flow to brain
- Stay hydrated
2. Medical Treatment
- Treat underlying cardiac or metabolic causes
- Adjust medications causing hypotension or dizziness
- Correct electrolyte imbalance or anemia
3. Lifestyle and Prevention
- Avoid sudden standing or rapid postural changes
- Adequate fluid intake
- Recognize early warning signs (lightheadedness)
- Compression stockings for orthostatic hypotension
4. Cardiac Intervention (if required)
- Pacemaker for severe bradyarrhythmias
- Ablation for certain tachyarrhythmias
- Valve repair or replacement for structural heart disease
Early recognition and management prevent injury and serious complications।
रोकथाम (Prevention)
- Maintain hydration and electrolyte balance
- Avoid prolonged standing in hot environments
- Manage chronic diseases (heart, diabetes, anemia)
- Monitor medications that lower blood pressure
- Recognize triggers and respond early to lightheadedness
सावधानियाँ (Precautions)
- Do not ignore repeated episodes of near-syncope
- Avoid driving or operating heavy machinery during episodes
- Seek urgent medical care if accompanied by chest pain, palpitations, or neurological deficits
- Follow treatment and monitoring recommendations
FAQs (अक्सर पूछे जाने वाले प्रश्न)
Q1. Near-syncope हमेशा खतरनाक होता है?
नहीं, लेकिन repeated या unexplained episodes serious cardiac or neurological cause indicate कर सकते हैं।
Q2. Near-syncope और syncope में अंतर क्या है?
Near-syncope में consciousness loss नहीं होता, syncope में व्यक्ति अस्थायी रूप से बेहोश हो जाता है।
Q3. कितनी जल्दी recover होता है?
Usually seconds to minutes में recovery होती है, लेकिन underlying cause treatment आवश्यक है।
Q4. क्या यह बच्चों में भी हो सकता है?
हाँ, लेकिन ज्यादा common adults में और elderly में होता है।
निष्कर्ष (Conclusion)
Near-Syncope (नीयर-सिंकॉप) एक warning sign हो सकता है जो cardiac, neurological या metabolic disorders की ओर इशारा करता है।
Early recognition, proper diagnosis, treatment of underlying cause, और lifestyle modifications से गंभीर complications और fall injuries prevent किए जा सकते हैं।
अगर किसी को lightheadedness, blurred vision, palpitations या weakness हो, तो तुरंत physician से consultation जरूरी है।
