Supraventricular Tachycardia
Overview The term supraventricular tachycardia (SVT), whilst often used synonymously with AV nodal re-entry tachycardia (AVNRT), can be used to refer to any tachydysrhythmia arising from above the level of the Bundle of His. Different types of SVT arise from or are propagated by the atria or AV node, typically producing a narrow-complex tachycardia (unless aberrant conduction is present). Classification…

Multiple Sclerosis
"Each patient ought to feel somewhat the better after the physician's visit irrespective of the nature of the illness." -Warfield Theobald Longcope Overview Multiple sclerosis (MS) is defined as an inflammatory demyelinating disease characterised by the presence of episodic neurological dysfunction in at least 2 areas of the CNS (brain, spinal cord, and optic nerves)…

Scaphoid Fracture
Overview Scaphoid fracture is the most common carpal bone fracture , accounting for ~60–70% of all carpal fractures. It occurs most frequently in young adults (15–40 years) following a fall on the outstretched hand (FOOSH). The scaphoid’s tenuous blood supply predisposes to non-union and avascular necrosis, especially in proximal fractures. Early recognition is essential as…

Carotid Sinus Hypersensitivity
Overview Carotid sinus hypersensitivity is an exaggerated autonomic response to stimulation of the carotid sinus. The resulting reflex may cause marked bradycardia, transient asystole, vasodilatation, hypotension, or a combination of these effects. This can reduce cerebral perfusion and produce presyncope or syncope. 1 Carotid sinus hypersensitivity is a physiological finding demonstrated during carotid sinus massage.…

Digoxin Toxicity
75 year old presents to emergency with a 2 day history nausea, vomiting, abdominal pain and diarrhoea. He has not been tolerating oral fluids and is currently confused with a GCS of 14. He has a past medical history of heart failure, atrial fibrillation and chronic kidney injury. He is on digoxin, metoprolol and an…

Undifferentiated Connective Tissue Disease (UCTD)
Overview UCTD is a systemic autoimmune disease with features of connective tissue disease (CTD), but does not fulfill classification criteria for any specific CTD such as SLE, Sjögren’s syndrome, systemic sclerosis, or polymyositis. It is a diagnosis of exclusion used for patients with persistent autoimmune features who do not evolve into a defined CTD. Commonly…

Asthma (Adults)
Clinical features of asthma such as dyspnoea, chest tightness and wheezing can mimic other respiratory conditions. It is important to take a careful history and examination and ideally demonstrate reversible airflow obstruction. Other clinical features of asthma arise during periods of bronchoconstriction (ie. exercise, smoking, stress, cold air). Exacerbation of asthma confounds the breathing difficulty, cough and wheeze in patients.

Good places to begin
Explanations learners return to.
Cardiomyopathy Overview – types (dilated, hypertrophic, restrictive), pathophysiology and treatment
Explore the different types of cardiomyopathy—dilated, hypertrophic, and restrictive—and how they affect heart structure and function. This video explains their pathophysiology, key clinical features, and treatment strategies to manage symptoms and prevent complications.
In Vitro Fertilization (IVF) – Overview
Learn the fundamentals of In Vitro Fertilization (IVF), including the step-by-step process, indications, and success factors. This video provides a clear overview of how IVF helps individuals and couples facing infertility achieve pregnancy.
Neurology – Neuron
Explore the structure and function of neurons, the fundamental units of the nervous system responsible for transmitting electrical and chemical signals. This video explains key parts of the neuron—such as the dendrites, axon, and synapse—and how they work together to facilitate communication within the body.
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…
