Marfans Syndrome
Overview Marfan's Syndrome is one of the most common inherited disorders of connective tissue. Marfan syndrome is a hereditary disease affecting connective tissues in the body, resulting in symptoms such as aortic dissection and musculoskeletal deformities. However, no family history of Marfan's does not exclude the diagnosis as 30% can occur through gene mutation. Marfan syndrome:…

Arrythmias
Overview An arrythmia refers to any disturbance in cardiac electrical activity that is not normal sinus rhythm with normal atrioventricular conduction. This may include changes in rate, rhythm or site of origin of the electrical signal for contraction. 1 Normal conduction of the heart For the heart to pump normally 2 : SA node initiates…

Systemic Lupus Erythematosus
Overview Systemic Lupus Erythematosus (SLE) is a chronic, multisystem autoimmune disease characterized by the production of autoantibodies and the deposition of immune complexes in various tissues. It predominantly affects women of childbearing age, with a female-to-male ratio of approximately 9:1. The disease is more prevalent among individuals of African, Asian, and Hispanic descent, and its…

Cystic Fibrosis
Overview Cystic fibrosis causes the dehydration of the mucus lumen causing thick sticky mucus to build up. This occurs mainly the lungs, causing productive cough and increasing rates in respiratory infections, and the pancreas causing pancreatic dysfunction. Cystic fibrosis occurs due to a mutation in the CFTR gene. Salty sweat is also another important characteristic…

Neck of Femur Fracture
Overview A neck of femur fracture is a fracture through the region connecting the femoral head to the femoral shaft. It is an intracapsular fracture because most of the femoral neck lies within the hip joint capsule. Neck of femur fractures most commonly occur in older adults following a low-energy fall, often in the presence…

DiGeorge Syndrome
Overview DiGeorge syndrome (22q11.2 deletion syndrome) is a congenital immunodeficiency and multisystem disorder caused by a microdeletion on chromosome 22. It leads to defective development of the third and fourth pharyngeal pouches, resulting in thymic hypoplasia/aplasia, hypocalcaemia due to parathyroid hypoplasia, and congenital heart defects. Prevalence is estimated at 1 in 4000 live births. Clinical…

Hyperlipidaemia
Overview Hyperlipidaemia is an umbrella term which encompasses genetic and acquired disorders that raise lipid levels within the blood. Hyperlipidaemia does not independently cause clinical symptoms, rather can lead to other disorders that can manifest in possible life-threatening presentations. Most notably, hyperlipidaemia causes atherosclerosis which may lead to cardiovascular, cerebrovascular, and peripheral vascular disease. 1…

Feeding the newborn: Is my baby eating enough?
Is my baby eating enough? A common question for new parents! In this video, we break down the signs that your newborn is getting enough milk, whether you're breastfeeding or formula feeding. Learn: – How often babies should feed – Wet and dirty nappy patterns – Growth and weight gain expectations – Hunger vs fullness…
Cardiac conduction and ventricular contraction – ECG correlation
Explore how the heart’s conduction system controls the timing of ventricular contraction and how these electrical events are represented on an ECG. This video breaks down the sequence of depolarization, mechanical response, and the meaning of ECG waves in clinical interpretation.
Amebiasis – entamoeba histolytica symptoms, pathophysiology, diagnosis, treatment
Amebiasis is a parasitic infection caused by entamoeba histolytica. Entamoeba histolytica infection is common worldwide and it can affect anyone, although it is more common in people who live in tropical areas with poor sanitary conditions. Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease. Entamoeba…
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Student, Neelain University
Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Aspiration Pneumonia
Overview Aspiration pneumonia is an acute pulmonary infection caused by inhalation of bacteria-rich oropharyngeal or upper gastrointestinal material into the lower respiratory tract. It occurs when aspiration is combined with impaired airway protection, ineffective clearance and sufficient pathogenic bacterial burden. It is particularly important in older adults, people with neurological disease, frailty, dysphagia or reduced…
