  2. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia , which start within the lower chambers of the heart . [ 2 ]

  3. Paroxysmal supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Paroxysmal...

    Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]

  4. Tachycardia - Wikipedia

    en.wikipedia.org/wiki/Tachycardia

    Any narrow complex tachycardia combined with a problem with the conduction system of the heart, often termed "supraventricular tachycardia with aberrancy" A narrow complex tachycardia with an accessory conduction pathway, often termed "supraventricular tachycardia with pre-excitation" (e.g. Wolff–Parkinson–White syndrome)

  5. AV nodal reentrant tachycardia - Wikipedia

    en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

    AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia.

    However, individuals may experience palpitations, dizziness, shortness of breath, or infrequently syncope (fainting or near fainting) during episodes of supraventricular tachycardia. WPW is also associated with a very small risk of sudden death due to more dangerous heart rhythm disturbances.

  8. Atrial flutter - Wikipedia

    en.wikipedia.org/wiki/Atrial_flutter

    AFL is the second most common pathologic supraventricular tachycardia but occurs at a rate less than one-tenth of the most common supraventricular tachycardia (atrial fibrillation). [2] [3] The overall incidence of AFL has been estimated at 88 cases per 100,000 person-years. The incidence of AFL is significantly lower (~5 cases/100,000 person ...

  9. Antiarrhythmic agent - Wikipedia

    en.wikipedia.org/wiki/Antiarrhythmic_agent

    Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
