Alcoholic Cardiomyopathy
Overview Alcoholic cardiomyopathy, increasingly termed alcohol-induced cardiomyopathy , is an acquired form of dilated cardiomyopathy caused by prolonged heavy alcohol exposure in the absence of another sufficient cause. It typically produces left ventricular dilatation and systolic dysfunction, leading to heart failure, arrhythmias, thromboembolism and sudden cardiac death. 1,2 The commonly used exposure threshold is more…

Acute Heart Failure
Overview Acute Heart Failure (AHF) is a life-threatening medical emergency defined as the rapid onset or sudden worsening of symptoms and signs of heart failure. It results from severe cardiac dysfunction leading to inadequate systemic cardiac output, elevated intracardiac pressures, or both. AHF can present either as de novo heart failure in a patient without…

Chicken Pox (Varicella Zoster)
Overview Chickenpox (Varicella) is an acute, highly contagious primary viral infection caused by the Varicella-Zoster Virus (VZV) , a member of the Herpesviridae family. It is classically characterized by a generalized, intensely pruritic, polymorphic rash that progresses rapidly from macules and papules to clear "dewdrop-like" vesicles before crusting over. Although varicella is typically a mild,…

Blount’s Disease
Overview Blount's disease, also called tibia vara, is a developmental growth disorder of the posteromedial proximal tibial physis. Asymmetric growth produces progressive genu varum centred below the knee, commonly with procurvatum, internal tibial torsion and relative shortening. It differs from physiological bowing because the deformity persists or progresses rather than following normal spontaneous correction.¹,² Early-onset…

Chagas Disease
Authors Megan Miner Armando Faigl Overview Chagas disease is caused by the parasitic protozoan Trypanosoma cruzi (T. cruzi) and is potentially life-threatening. These parasites often live within triatomine bugs. Following a bite to the skin, these bugs, also known as “kissing bugs”, deposit fecal matter near the site of the bite. Their bite, unfortunately, causes…

Knee Osteoarthritis (KOA)
Overview Knee osteoarthritis is a chronic, whole-joint disorder characterized by pain, stiffness, functional limitation and progressive structural change affecting cartilage, subchondral bone, synovium, menisci, ligaments and peri-articular muscles. Prevalence rises with age and obesity and contributes substantially to global disability; recent GBD analyses and reviews highlight knee OA as a leading cause of pain and…

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…

Videos
Hand-drawn explanations that build the big picture as the concept unfolds.
Notes
Clear written explanations for review, reference and filling in the details.
Diagrams
Visual snapshots that help you easily review topics.
Questions

Good places to begin
Explanations learners return to.
Inflammatory bowel disease – Pathophysiology
Chemistry Revision V – Chemical Bonds
Learn the fundamentals of chemical bonds, including ionic, covalent, and metallic bonding, and how atoms achieve stability through electron interactions. This educational video breaks down bond types, properties, and examples—essential for mastering basic chemistry and exam preparation.
Iron Physiology
Explore iron physiology, including its absorption, transport, storage, and role in vital processes like oxygen transport and cellular respiration. This video explains how the body regulates iron levels and the significance of proteins like transferrin, ferritin, and hepcidin.
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.

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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
