bradycardia
Let an agent explain bradycardia in general terms, relay causes, symptoms, tests and treatments from cardiology sources, route fainting, chest pain, severe breathlessness or confusion to emergency services, describe the kinds the registry aliases name, and distinguish bradycardia from tachycardia, heart block as one cause and athletic heart, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain bradycardia in general terms, relay causes, symptoms, tests and treatments from cardiology sources, route fainting, chest pain, severe breathlessness or confusion to emergency services, describe the kinds the registry aliases name, and distinguish bradycardia from tachycardia, heart block as one cause and athletic heart, without diagnosing individuals.
A slower than normal heart rate, usually defined in adults as below 60 beats per minute at rest, which can be normal in fit people and during sleep but can also result from sinus node dysfunction, heart conduction disease such as atrioventricular block and atrial conduction disease, medications, hypothyroidism or reflex responses; symptomatic bradycardia with fainting, chest pain or breathlessness needs urgent medical care. Kinds include sinus bradycardia, ventricular bradycardia and reflex bradycardia; the registry alias catecholaminergic polymorphic ventricular tachycardia is a fast rhythm disorder and appears misfiled.
What it is for: Not applicable; a heart rate finding.
It can be explain in general terms; relay causes and treatments; route symptoms to emergency care; distinguish related rhythms.
Distinguishing features
Slow rate
Can be normal
Conduction causes
Pacemaker treatable
What it looks like
Not a visible object; seen as a slow rate on a pulse check or ECG.
Physical character
adult threshold: below 60 beats per minute - resting, some use 50
main test: electrocardiogram note
main device treatment: pacemaker note - for symptomatic cases
How it is recognised
Slow heart rate
Sinus bradycardia, ventricular bradycardia, reflex bradycardia, heart and atrial conduction disease
Tachycardia is fast; heart block is one cause; athletic bradycardia is often benign
