  2. Supraventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Supraventricular_tachycardia

    A 12-lead ECG showing paroxysmal supraventricular tachycardia at about 180 beats per minute. Subtypes of SVT can often be distinguished by their electrocardiogram (ECG) characteristics. Most have a narrow QRS complex, although, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular ...

  3. Atrioventricular reentrant tachycardia - Wikipedia

    en.wikipedia.org/wiki/Atrioventricular_reentrant...

    An episode of SVT may present with palpitations, dizziness, shortness of breath, or losing consciousness (fainting). The electrocardiogram (ECG) would appear as a narrow-complex SVT. Between episodes of tachycardia the affected person is likely to be asymptomatic; however, the ECG would demonstrate the classic delta wave in Wolff–Parkinson ...

    They may be classified into narrow and wide complex based on the QRS complex. [10] Equal or less than 0.1s for narrow complex. [11] Presented in order of most to least common, they are: [10] Narrow complex Sinus tachycardia, which originates from the sino-atrial (SA) node, near the base of the superior vena cava; Atrial fibrillation; Atrial flutter

    WPW pattern with hemodynamically stability and orthodromic AVRT leading to a regular narrow complex tachycardia may be managed similarly to other regular narrow complex supraventricular tachycardias: first with vagal maneuvers followed by a trial of adenosine (first-line therapy). The 2015 ACC/AHA/HRS guidelines recommend beta-blockers or ...

  6. AV nodal reentrant tachycardia - Wikipedia

    en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

    AV-nodal reentrant tachycardia; Other names: Atrioventricular-nodal reentrant tachycardia: An example of an ECG tracing typical of uncommon AV nodal reentrant tachycardia. Highlighted in yellow is the P wave that falls after the QRS complex. Specialty: Cardiology: Symptoms: Palpitations, chest tightness, neck pulsation: Diagnostic method

  7. Junctional ectopic tachycardia - Wikipedia

    en.wikipedia.org/wiki/Junctional_Ectopic_Tachycardia

    JET is most commonly diagnosed using a 12-lead ECG. The appearance is usually of a tachycardia with rapid, regular ventricular rates of 170-260 beats per minute. [6] The QRS complexes are usually narrow, but may be broad if a bundle branch block is present. There may a 1:1 relationship between atria and ventricular activity with a short RP ...

  8. Junctional tachycardia - Wikipedia

    en.wikipedia.org/wiki/Junctional_tachycardia

    Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia . It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [ 2 ]

  9. Outline of cardiology - Wikipedia

    en.wikipedia.org/wiki/Outline_of_cardiology

    Supraventricular tachycardia (SVT) – A collection of tachycardia rhythms that originate before the ventricles and include the SA node, atria, and AV node. It is a broad, encompassing term that includes other rhythms in this list (e.g., afib with RVR) and others.
