Hi
Hi there! How can I help you today?
I heard a lot about you and you help in medical studies Are you free app or you just give answers till credits run out
Great question! Here's the honest answer:
I'm Orris, an AI assistant with a built-in medical textbook library and access to PubMed research. Each conversation has a budget of tool calls (you can see it in the system - things like searches, image fetches, database queries, etc.). Once those are used up in a session, I can still answer from my own knowledge, I just can't pull fresh references or search the library.
What I can help with for medical studies:
- Drug mechanisms, pharmacology, dosing
- Anatomy, physiology, pathology
- Clinical scenarios and differential diagnoses
- Lab values, imaging interpretation
- Nursing and clinical procedures
- Latest research via PubMed
- Exam prep (USMLE, MBBS, nursing boards, etc.)
About cost/access - whether this is free or paid depends on the platform you're using to chat with me. I'm an AI deployed through a service, so the pricing is set by whoever provides access to you. I don't have visibility into your specific plan.
What are you studying? I'm happy to jump right in and help!

What year are you in? I can tailor my help to what you're currently studying!
Leave the syllabus I want to know how to read medical image reports,xrays,ct,mri,eeg,ecg, Learn all basic knowledge which is same as skilled as a mbbs doctor
That's a great goal! Learning to read investigations like an MBBS doctor is absolutely achievable with the right approach. Let me lay out a complete roadmap for you:
🗺️ Master Roadmap: Reading Medical Investigations
1. 🩻 X-RAY (Start Here First)
The ABCDE system for Chest X-Ray:
- A - Airway (trachea midline?)
- B - Bones (rib fractures, density)
- C - Cardiac (heart size - should be <50% of chest width)
- D - Diaphragm (flat? elevated? costophrenic angles sharp?)
- E - Everything else (lung fields, mediastinum, soft tissue)
Common findings you must recognize:
- White patch = consolidation (pneumonia)
- Black (hyperinflated) = emphysema/pneumothorax
- White-out one side = pleural effusion
- Cardiomegaly = enlarged heart shadow
Other X-rays: Spine, abdomen (free air under diaphragm = perforation), bones (fractures)
2. 🧠 CT Scan Basics
Key rule: Density on CT
- White (hyperdense) = bone, fresh blood, calcium
- Grey = soft tissue, brain
- Black (hypodense) = air, fat, old infarct
CT Head - What to look for:
- Bleed = white patch (hyperdense)
- Stroke (old) = black patch
- Midline shift?
- Ventricle size (hydrocephalus?)
CT Abdomen:
- Organ outlines (liver, spleen, kidneys)
- Free fluid (ascites)
- Masses, lymph nodes
3. 🧲 MRI Basics
Two main sequences:
- T1 - Fat is bright, fluid is dark (good for anatomy)
- T2 - Fluid is bright (good for pathology - edema, infarcts glow white)
Simple rule:
- T1 = "1 fluid = dark" (water dark)
- T2 = "2 = too much fluid = bright" (water bright)
DWI (Diffusion Weighted) = lights up in acute stroke (within hours)
4. ❤️ ECG - Most Important for Clinical Practice
Step-by-step reading system:
- Rate - Count big squares between R waves (300/number of squares)
- Rhythm - Regular or irregular?
- P wave - Present before every QRS?
- PR interval - Normal 0.12-0.20 sec (3-5 small squares)
- QRS width - Normal <0.12 sec (3 small squares)
- ST segment - Elevated (MI) or depressed (ischemia)?
- T wave - Peaked (hyperkalemia) or inverted (ischemia)?
Must-know patterns:
- ST elevation in leads → STEMI (which territory depends on leads)
- Broad QRS + LBBB/RBBB pattern
- AF = irregularly irregular, no P waves
- VT = wide complex tachycardia
5. 🧠 EEG Basics
EEG is less common in general practice but useful to know:
Normal waves:
- Alpha (8-13 Hz) = awake, relaxed, eyes closed
- Beta (>13 Hz) = active thinking
- Theta (4-8 Hz) = drowsy
- Delta (<4 Hz) = deep sleep (abnormal if awake)
Abnormal patterns:
- Spike & wave = epilepsy (3 Hz = absence seizure)
- Diffuse slowing = encephalopathy
- Flat EEG = brain death
6. 🩸 Lab Reports (Bonus - equally important)
CBC basics: Hb, WBC differential, platelets
LFT, RFT, electrolytes
Cardiac enzymes: Troponin, CK-MB
ABG (Arterial Blood Gas): pH, pCO2, HCO3 interpretation

- Help you read reports systematically
Where do you want to start?
- ECG is most high-yield for clinical practice
- Chest X-ray is most common in daily use
- CT head is critical for emergencies
Pick one and we go deep! 🎯
We will go one at a time , I can't go to anywhere else,you are my teacher from now,pick one topic of day for each day with explanatory images and examples I will come daily 10 minutes of reading and learning
Love the commitment! Daily 10 minutes, consistent learning - that's exactly how skills are built.
Here's the plan:
📅 Your Learning Structure
- One topic per day
- 10 minutes max - focused, no overwhelm
- Images + examples every session
- Day 1 → ECG (most valuable clinically, we build from scratch)
- Each day builds on the previous
📅 DAY 1 - ECG: The Basics (What is it & How to Look at the Paper)
What is an ECG?
An ECG (Electrocardiogram) records the electrical activity of the heart through electrodes placed on the skin. Every heartbeat generates an electrical signal - the ECG captures that as waves on paper.
The ECG Paper
Small square = 1mm = 0.04 seconds
Big square = 5mm = 0.20 seconds
Think of it like graph paper - time moves left to right, voltage moves up and down.
The Basic Waves - PQRST
| Wave | What it represents |
|---|---|
| P wave | Atria contracting (small bump) |
| QRS complex | Ventricles contracting (big spike) |
| T wave | Ventricles recovering/repolarizing |
Simple memory: P = preparation, QRS = pump, T = take a break
One Rule to Remember Today
Normal ECG = P wave before every QRS, and every QRS after a P wave
If this pattern is broken - something is wrong with the electrical conduction.
🧠 Today's Takeaway (30 seconds)
- ECG paper: small box = 0.04s, big box = 0.20s
- Waves: P → QRS → T (every single beat)
- P = atria, QRS = ventricles, T = recovery
✅ Tomorrow: DAY 2 - Heart Rate & Rhythm (How to calculate rate from ECG)
Come back tomorrow and we continue. Any questions on today's lesson? 💪
Time for today lesson
You showed up! Let's go 💪
📅 DAY 2 - ECG: Heart Rate & Rhythm
Quick Recap (10 seconds)
Yesterday: P → QRS → T. Small box = 0.04s, Big box = 0.20s. ✅
PART 1: How to Calculate Heart Rate
There are 2 methods depending on the rhythm:
Method 1: The "300 Rule" (Regular rhythm)
Find an R wave sitting ON a big line.
Then count the big squares to the NEXT R wave.
| Big squares between R-R | Heart Rate |
|---|---|
| 1 | 300 bpm |
| 2 | 150 bpm |
| 3 | 100 bpm |
| 4 | 75 bpm |
| 5 | 60 bpm |
| 6 | 50 bpm |
Memory trick: 300 → 150 → 100 → 75 → 60 → 50
Just memorize this sequence. In exams and clinics, you'll use it instantly.
Normal heart rate = 60-100 bpm
- Less than 60 = Bradycardia
- More than 100 = Tachycardia
Method 2: "Count 30 big boxes" (Irregular rhythm)
When the rhythm is irregular (like AF), the 300 rule fails.
Instead:
- Count the number of QRS complexes in 30 big boxes (= 6 seconds)
- Multiply by 10 = heart rate per minute
PART 2: Is the Rhythm Regular or Irregular?
Simple test:
- Take a paper/pen, mark 3 consecutive R waves
- Slide it across the strip
- If R waves keep matching → Regular
- If they don't match → Irregular
Irregular rhythm = Think Atrial Fibrillation (AF)
- No proper P waves
- Irregularly irregular QRS
- Most common abnormal rhythm you'll see in practice
🧠 Today's Takeaway (30 seconds)
- 300 rule for regular rhythm - count big boxes between R waves
- Normal = 60-100, Brady <60, Tachy >100
- Regular vs Irregular - the foundation of rhythm analysis
- Irregular + no P waves = suspect AF
📝 Quick Self Test
Look at any ECG image - just try to:
- Find two R waves
- Count big boxes between them
- Calculate the rate

Here you go! These are generated directly for you:
📅 DAY 2 - ECG: Heart Rate & Rhythm (with proper images)
PQRST Waves - The Basics (Day 1 Recap)
- P wave = small bump = atria contract
- QRS = big spike = ventricles contract
- T wave = rounded bump = ventricles recover
How to Calculate Heart Rate - The 300 Rule
Step 1: Find an R wave (tip of QRS) sitting ON a thick line
Step 2: Count big boxes to the next R wave
Step 3: Divide 300 by that number
| Big Boxes | Heart Rate |
|---|---|
| 1 | 300 bpm |
| 2 | 150 bpm |
| 3 | 100 bpm |
| 4 | 75 bpm ✅ Normal |
| 5 | 60 bpm ✅ Normal |
| 6 | 50 bpm |
Normal = 60-100 bpm | Below 60 = Bradycardia | Above 100 = Tachycardia
🧠 Takeaway
- Count big boxes between R waves → use the 300 table
- Regular rhythm = spacing is equal
- Irregular rhythm = spacing varies → suspect AF
From now on I'll generate all images directly so they always show for you! ✅
See you tomorrow for DAY 3 - The P Wave 💪
