π ECG (Electrocardiogram) β Poori Guide Hindi Mein
ECG Kya Hota Hai?
ECG ek test hai jo dil ki electrical activity ko record karta hai. Har baar dil dhakdhakta hai, electricity ek pattern mein chalti hai β aur ECG woh pattern paper ya screen par dikhata hai.
β‘ ECG Ki Basic Waves β PQRST
Har heartbeat mein yeh waves hoti hain:
| Wave | Kya Hoti Hai | Normal Value |
|---|---|---|
| P wave | Atria (upar ke chambers) ka contract hona | Choti, rounded |
| PR interval | P se QRS tak ka samay | 0.12β0.20 sec |
| QRS complex | Ventricles (neeche ke chambers) ka contract hona | 0.06β0.12 sec |
| ST segment | Ventricles ka rest | Isoelectric line par hona chahiye |
| T wave | Ventricles ka recharge hona | Positive (upward) |
| QT interval | Q se T tak ka samay | < 0.44 sec |
π’ Normal ECG (Sinus Rhythm)
Yeh dekho β normal ECG kaisi dikhti hai:
Normal ECG mein:
- Har QRS se pehle ek P wave hoti hai β
- Rhythm regular hoti hai β
- Heart rate: 60β100 bpm β
- ST segment seedha hota hai β
π₯ Common Diseases aur ECG Changes
1. π΄ Heart Attack (STEMI β ST Elevation Myocardial Infarction)
Pehchaan: ST segment oopar uth jaata hai (elevation)
Kya dikhta hai:
- ST elevation β V1 se V6 mein (anterior wall attack β LAD artery block)
- Inferior leads (II, III, aVF) mein ST elevation β Right Coronary Artery block
- Reciprocal changes β opposite leads mein ST depression
- Yeh EMERGENCY hai β patient ko turant angioplasty chahiye!
2. π Atrial Fibrillation (AF)
Pehchaan: P waves gayab ho jaati hain, rhythm bilkul irregular
Kya dikhta hai:
- β Koi organized P wave nahi
- Baseline mein fibrillatory waves (titilte hue)
- R-R intervals β bilkul irregular ("irregularly irregular")
- Causes: hypertension, valve disease, thyroid, alcohol
3. π Ventricular Tachycardia (VT)
Pehchaan: Wide QRS complexes, bahut tez rate
Kya dikhta hai:
- Wide bizarre QRS (>0.12 sec)
- Rate: 150β250 bpm
- P waves nahi dikhte
- Life-threatening β cardioversion ki zaroorat
π ECG Padhne Ka Systematic Tarika (7 Steps)
Jab bhi ECG dekho, yeh order follow karo:
1. RATE β Kitni bpm? (300 Γ· R-R boxes)
2. RHYTHM β Regular hai ya irregular?
3. P WAVES β Har QRS se pehle P wave hai?
4. PR INTERVAL β 0.12-0.20 sec hai?
5. QRS WIDTH β Narrow (<0.12) ya wide (>0.12)?
6. ST SEGMENT β Elevated, depressed ya normal?
7. T WAVES β Upright hain ya inverted?
πΊοΈ 12 Leads β Kaunsa Lead Dil Ka Kaunsa Hissa Dekhta Hai?
| Leads | Dil Ka Hissa |
|---|---|
| II, III, aVF | Inferior wall (neeche) β RCA |
| V1βV4 | Anterior wall (aage) β LAD |
| I, aVL, V5βV6 | Lateral wall (baaju) β LCx |
| V1βV2 | Posterior wall (peeche se dekhne ke liye) |
β‘ Quick Summary Table β Common ECG Abnormalities
| Bimari | ECG Finding |
|---|---|
| Heart Attack (STEMI) | ST elevation + reciprocal depression |
| Angina (NSTEMI) | ST depression + T wave inversion |
| Atrial Fibrillation | No P waves, irregular rhythm |
| Ventricular Tachycardia | Wide QRS, fast rate, no P waves |
| Complete Heart Block | P waves aur QRS ka koi relation nahi |
| Bundle Branch Block | QRS >0.12 sec (W pattern LBBB, M pattern RBBB) |
| Hyperkalemia | Peaked T waves β sine wave β cardiac arrest |
| Long QT | QT interval prolonged β Torsades de Pointes risk |

π©Έ CBC (Complete Blood Count) β Poori Guide Hindi Mein
CBC Kya Hota Hai?
CBC ek blood test hai jo khoon ke teen main components ko measure karta hai:
- RBC β Red Blood Cells (lal khoon ke kankshaye)
- WBC β White Blood Cells (safed khoon ke kankshaye)
- Platelets β Khoon rokne waali cells
Yeh test doctor ko batata hai ki anemia hai, infection hai, cancer hai, ya bleeding problem hai.
π΄ PART 1 β RBC (Red Blood Cells) β Lal Khoon
Yeh cells oxygen poore body mein pohnchaati hain. Inke andar Hemoglobin (Hb) hota hai jo oxygen carry karta hai.
Normal Values (Adult):
| Parameter | Full Form | Normal Range | Kya Measure Karta Hai |
|---|---|---|---|
| Hb | Hemoglobin | M: 13β17 g/dL, F: 12β15 g/dL | Oxygen carry karne ki taakat |
| RBC | Red Blood Cell count | M: 4.5β5.5 million/Β΅L, F: 4β5 million/Β΅L | Lal cells ki ginti |
| Hct/PCV | Hematocrit | M: 40β52%, F: 36β48% | Khoon mein RBC ka hissa |
| MCV | Mean Corpuscular Volume | 80β100 fL | Ek RBC ka size |
| MCH | Mean Corpuscular Hemoglobin | 27β33 pg | Ek cell mein Hb kitna |
| MCHC | MCH Concentration | 32β36 g/dL | Cells kitni "bhuri" (colored) hain |
| RDW | RBC Distribution Width | 11.5β14.5% | Cells ka size kitna vary karta hai |
Anemia β Hb Kam Hona
Anemia = Hemoglobin low β Body mein oxygen kam pohnchrha hai
3 types MCV ke hisaab se:
π΅ Microcytic Anemia (MCV < 80 β Chhoti cells)
Normal vs Iron Deficiency comparison β Left normal cells, Right mein chhoti, pale cells:
| Cause | Key Finding |
|---|---|
| Iron Deficiency (sabse common) | Serum ferritin β, TIBC β |
| Thalassemia | Target cells, Hb electrophoresis abnormal |
| Chronic disease | Ferritin normal/high, TIBC β |
Symptoms: Thakaan, pallor (haath-aankhon ki safedi), dil ki tez dhadkan
π‘ Normocytic Anemia (MCV 80β100 β Normal size)
| Cause |
|---|
| Acute blood loss |
| Hemolytic anemia (cells toot rahe hain) |
| Aplastic anemia (bone marrow fail) |
| Kidney disease (EPO kam) |
π΄ Macrocytic Anemia (MCV > 100 β Badi cells)
| Cause | Key Finding |
|---|---|
| B12 deficiency | Neurological symptoms bhi |
| Folate deficiency | Pregnancy mein common |
| Liver disease / Alcohol | History se pata chalti hai |
π©Ί PART 2 β WBC (White Blood Cells) β Safed Khoon
Yeh immune system ke soldiers hain β infection, allergy, cancer se ladte hain.
Normal WBC: 4,000β11,000 /Β΅L
WBC ke Types (Differential Count):
| Cell | % (Normal) | Kaam | Increase (β) Matlab |
|---|---|---|---|
| Neutrophil | 50β70% | Bacteria se ladta hai | Bacterial infection, stress |
| Lymphocyte | 20β40% | Virus se ladta hai, antibodies banata hai | Viral infection, leukemia |
| Monocyte | 2β8% | Bacteria khata hai (phagocytosis) | TB, fungal infection |
| Eosinophil | 1β4% | Allergy, parasites se ladta hai | Allergy, asthma, worms |
| Basophil | 0β1% | Allergic reaction mein | Allergic reaction, CML |
WBC Abnormalities:
| Finding | Normal Range | Kya Matlab |
|---|---|---|
| Leukocytosis (WBC > 11,000) | β | Infection, inflammation, leukemia |
| Leukopenia (WBC < 4,000) | β | Viral infection, chemotherapy, aplastic anemia |
| Neutrophilia (Neutrophil β) | β | Bacterial infection, steroids |
| Lymphocytosis (Lymphocyte β) | β | Viral infection (dengue, COVID), CLL |
| Eosinophilia (Eosinophil β >4%) | β | Allergy, asthma, intestinal worms |

| Finding | Kya Matlab |
|---|---|
| Thrombocytopenia (< 1.5 lakh) | Dengue, ITP, leukemia, chemotherapy β bleeding ka risk |
| < 20,000 | Spontaneous bleeding ka danger! |
| Thrombocytosis (> 4 lakh) | Iron deficiency, infection, essential thrombocythemia |
π Ek Poori CBC Kaise Padhein β Step by Step
Step 1: Hb dekho β Anemia hai?
β Low β MCV dekho β Micro/Normo/Macro?
Step 2: WBC dekho β
β High β Differential dekho (Neutrophil ya Lymphocyte?)
β Low β Viral? Chemo? Aplastic?
Step 3: Platelets dekho β
β Low β Dengue? ITP? Bleeding risk?
β High β Infection? Thrombocythemia?
π§Ύ Quick Summary β Common CBC Patterns
| Pattern | Diagnosis |
|---|---|
| Hbβ, MCVβ, Ferritinβ | Iron deficiency anemia |
| Hbβ, MCVβ, B12β | B12 / Folate deficiency anemia |
| WBCβ (Neutrophilβ), Fever | Bacterial infection |
| WBCβ (Lymphocyteβ), Fever | Viral infection (dengue, typhoid) |
| Plateletsβ + Fever | Dengue |
| Hbβ + WBCβ + Plateletsβ (Pancytopenia) | Aplastic anemia / Leukemia / Chemotherapy |
| Blast cells present | Acute Leukemia β EMERGENCY! |
