Acetylcholinesterase inhibitor
An acetylcholinesterase inhibitor (often abbreviated AChEI) or anti-cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine.

Artificial cardiac pacemaker
A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker) is a medical device that generates electrical impulses delivered by electrodes to contract the heart muscles and regulate the electrical conduction system of the heart.

Atrioventricular block
Atrioventricular block (AV block) is a type of heart block in which the conduction between the atria and ventricles of the heart is impaired.

Atrioventricular node
The atrioventricular node, or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.

Beta blocker
Beta blockers, also written β-blockers, are a class of medications that are particularly used to manage abnormal heart rhythms, and to protect the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention).

Cardiac glycoside
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by acting on the cellular sodium-potassium ATPase pump.

Digoxin
Digoxin, sold under the brand name Lanoxin among others, is a medication used to treat various heart conditions.

Electrical conduction system of the heart
The electrical conduction system of the heart transmits signals generated usually by the sinoatrial node to cause contraction of the heart muscle.

Myocardial infarction
Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.

PR interval
In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200ms in duration.
