  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. Premature atrial contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_atrial_contraction

    A supraventricular extrasystole (SVES) is an extrasystole or premature electrical impulse in the heart, generated above the level of the ventricle. This can be either a premature atrial contraction or a premature impulse from the atrioventricular node .

  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. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    Premature ventricular complex, ventricular premature contraction (complex or complexes) (VPC), ventricular premature beat (VPB), ventricular extrasystole (VES) Premature ventricular contraction usually originates from an area of Ectopic focus. In this illustration ectopic area is near papillary muscles in the left ventricle.

  6. 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]

  7. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

  8. AV nodal reentrant tachycardia - Wikipedia

    en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

    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. It is more common in women than men (approximately 75% of cases occur in females). The main symptom is palpitations.
