Adenosine is both a chemical found in many living systems and a medication.
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a group of pharmaceuticals that are used to suppress abnormal rhythms of the heart (cardiac arrhythmias), such as atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation.
Anticoagulants, commonly referred to as blood thinners, are chemical substances that prevent or reduce coagulation of blood, prolonging the clotting time.

Apixaban, sold under the tradename Eliquis, is an anticoagulant for the treatment of venous thromboembolic events.
Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating of the atria.
The atrioventricular node, or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.
The atrium is the upper chamber in which blood enters the heart.
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).
Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists are several medications that disrupt the movement of calcium through calcium channels.
Cardiology (from Greek καρδίᾱ kardiā, "heart" and -λογία -logia, "study") is a branch of medicine dealing with disorders of the heart as well as parts of the circulatory system.
Cardiomyopathy is a group of diseases that affect the heart muscle.
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs.
Catheter ablation is a procedure used to remove or terminate a faulty electrical pathway from sections of the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardias (SVT) and Wolff-Parkinson-White syndrome (WPW syndrome).
The cavo-tricuspid isthmus is a body of fibrous tissue in the lower right atrium between the inferior vena cava, and the tricuspid valve.
Coronary artery disease (CAD), also known as ischemic heart disease (IHD), refers to a group of diseases which includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death.
Death is the cessation of all biological functions that sustain a living organism.
Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period.
Diltiazem (INN) is a nondihydropyridine (non-DHP) calcium channel blocker used in the treatment of hypertension, angina pectoris, and some types of arrhythmia.
Dofetilide is a class III antiarrhythmic agent.
Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.
An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel.
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
Heart arrhythmia (also known as arrhythmia, dysrhythmia, or irregular heartbeat) is a group of conditions in which the heartbeat is irregular, too fast, or too slow.
Heart block is a disease or inherited condition that causes a fault within the heart's natural pacemaker due to some kind of obstruction (or "block") in the electrical conduction system of the heart.
Heart failure (HF), often referred to as congestive heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated.
Hypotension is low blood pressure, especially in the arteries of the systemic circulation.
Ibutilide is a Class III antiarrhythmic agent that is indicated for acute cardioconversion of atrial fibrillation and atrial flutter of a recent onset to sinus rhythm.
The inferior vena cava (or IVC) is a large vein that carries deoxygenated blood from the lower and middle body into the right atrium of the heart.
Ischemia or ischaemia is a restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive).
A Lewis Lead (also called the S5 lead) is a modified EKG lead used to detect atrial flutter waves when atrial flutter is suspected clinically, based on signs and symptoms, but is not definitely demonstrated on the standard 12 lead EKG.
A man-hour, or less commonly person-hour, is the amount of work performed by the average worker in one hour.
The management of atrial fibrillation (AF) is focused on preventing temporary circulatory instability and to prevent stroke and other ischemic events.
Metoprolol, marketed under the tradename Lopressor among others, is a medication of the selective β1 receptor blocker type.
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.
Nausea or queasiness is an unpleasant sense of unease, discomfort, and revulsion towards food.
Palpitations are the perceived abnormality of the heartbeat characterized by awareness of cardiac muscle contractions in the chest: hard, fast and/or irregular beats.
Premature atrial contractions (PACs), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria.
Refractoriness is the fundamental property of any object of autowave nature (especially excitable medium) not to respond on stimuli, if the object stays in the specific refractory state.
Shortness of breath, also known as dyspnea, is the feeling that one cannot breathe well enough.
A stroke is a medical condition in which poor blood flow to the brain results in cell death.
Supraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart.
Syncope, also known as fainting, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery.
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate.
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) cause an impairment of the myocardium (heart muscle), which can result in heart failure.
Sir Thomas Lewis, CBE, FRS, FRCP (26 December 1881 – 17 March 1945) was a British cardiologist (although he personally disliked the term, preferring cardiovascular disease specialist).

The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, between the right atrium and the right ventricle.
