Bradycardia, as applied to adult medicine, is defined as a resting heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min. A symptom' (from Greek σύμπτωμα, "accident misfortune that which befalls" from συμπίπτω, "I befall" from A Sign is an indication of some fact or quality and a medical sign is an objective indication of some medical fact or quality that is detected by a Physician The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The International Statistical Classification of Diseases and Related Health Problems 10th Revision ( ICD -10) is a coding of diseases and signs symptoms abnormal findings R00-R69 - Symptoms and Signs (R00-R09 Circulatory and Respiratory systems ( Abnormalities of Heart beat The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The following is a list of codes for International Statistical Classification of Diseases and Related Health Problems. Measuring heart rate The Pulse rate (which in most people is identical to the heart rate can be measured at any point on the body where an Artery 's pulsation [1] Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it. A sportsperson ( British and American English) or athlete (principally American English is any person who participates regularly in a Sport.
The term relative bradycardia is used to explain a heart rate that, while not technically below 60 beats per minute, is considered too slow for the individual's current medical condition.
This cardiac arrhythmia can be underlain by several causes, which are best divided into cardiac and non-cardiac causes. Dysrhythmia redirects here For the American band see Dysrhythmia (band. Non-cardiac causes are usually secondary, and can involve drug use or abuse; metabolic or endocrine issues, especially in the thyroid; an electrolyte imbalance; neurologic factors; autonomic reflexes; situational factors such as prolonged bed rest; and autoimmunity. Recreational drug use is the use of Psychoactive drugs for Recreational purposes rather than for work, medical or spiritual purposes Drug abuse has a wide range of definitions related to taking a Psychoactive drug or Performance enhancing drug for a non-therapeutic or non-medical effect Metabolism is the set of Chemical reactions that occur in living Organisms in order to maintain Life. The endocrine system is an integrated system of small organs that involve the release of extracellular signaling molecules known as Hormones The endocrine system is instrumental The thyroid is one of the largest Endocrine glands in the body An electrolyte is any substance containing free Ions that behaves as an electrically conductive medium Bed rest is a Doctor's prescription to spend a longer period of time in bed Autoimmunity is the failure of an organism to recognize its own constituent parts as self, which results in an immune response against its own cells and tissues Cardiac causes include acute or chronic ischemic heart disease, vascular heart disease, valvular heart disease, or degenerative primary electrical disease. Ischaemic or ischemic heart disease (IHD or myocardial ischaemia, is a Disease characterized by reduced blood supply to the heart muscle Heart disease is an Umbrella term for a variety for different diseases affecting the Heart. Ultimately, the causes act by three mechanisms: depressed automaticity of the heart, conduction block, or escape pacemakers and rhythms.

Causes
There are generally two types of problems that result in bradycardias: disorders of the sinus node, and disorders of the atrioventricular node (AV node). The Sinoatrial node (abbreviated SA node or SAN, also called the sinus node) is the impulse generating (pacemaker tissue located in the Right atrium The atrioventricular node (abbreviated AV node) is an area of specialized tissue between the atria and the ventricles of the Heart, specifically
With sinus node dysfunction (sometimes called sick sinus syndrome), there may be disordered automaticity or impaired conduction of the impulse from the sinus node into the surrounding atrial tissue (an "exit block"). Sick sinus syndrome, also called Sinus node dysfunction, is a group of abnormal heart rhythms ( Arrhythmias presumably caused by a malfunction of the Sinus Automaticity (ˌɔːtəməˈtɪsɨti is the ability to do things without occupying the mind with the low level details required It is difficult and sometimes impossible to assign a mechanism to any particular bradycardia, but the underlying mechanism is not clinically relevant to treatment, which is the same in both cases of sick sinus syndrome: a permanent pacemaker. For other uses see Pacemaker (disambiguation A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker
Atrioventricular conduction disturbances (aka: AV block; 1o AV block, 2o type I AV block, 2o type II AV block, 3o AV block) may result from impaired conduction in the AV node, or anywhere below it, such as in the bundle of HIS. First degree AV block or PR prolongation is a disease of the electrical conduction system of the Heart in which the PR interval is lengthened Second degree AV block is a disease of the electrical conduction system of the Heart. Second degree AV block is a disease of the electrical conduction system of the Heart. Third degree AV block, also known as complete heart block, is a defect of the electrical system of the Heart, in which the impulse generated in the atria (typically
Patients with bradycardia have likely acquired it, as opposed to having it congenitally. A congenital disorder is a disease or disorder that is present at birth Bradycardia is more common in older patients.
Management
There are 2 main reasons for treating any cardiac arrhythmias. Dysrhythmia redirects here For the American band see Dysrhythmia (band. With bradycardia, the first is to address the associated symptoms, such as fatigue, limitations on how much an individual can physically exert, fainting (syncope), dizziness or lightheadedness, or other vague and non-specific symptoms. Many different terms are often used to describe what is collectively known as dizziness. The other reason to treat bradycardia is if the person's ultimate outcome (prognosis) will be changed or impacted by the bradycardia. Treatment in this vein depends on whether any symptoms are present, and what the underlying cause is. Primary or idiopathic bradycardia is treated symptomatically if it is significant, and the underlying cause is treated if the bradycardia is secondary. Idiopathic is an Adjective used primarily in Medicine meaning arising spontaneously or from an obscure or unknown cause.
Treatment
Drug treatment for bradycardia is typically not indicated for patients who are asymptomatic. In symptomatic patients, underlying electrolyte or acid-base disorders or hypoxia should be corrected first. IV atropine may provide temporary improvement in symptomatic patients, although its use should be balanced by an appreciation of the increase in myocardial oxygen demand this agent causes.
