supraventricular tachycardia

(noun)

Any rapid heart rhythm originating at or above the atrioventricular node.

Related Terms

  • Cardiac arrhythmia (irregular heartbeat)
  • automaticity

Examples of supraventricular tachycardia in the following topics:

  • Arrhythmia

    • Arrhythmias - types: Arrhythmia may be classified by rate (normal, tachycardia, bradycardia), or mechanism (automaticity, reentry, fibrillation).
    • Arrhythmias arising at the junction: Supraventricular tachycardia (SVT), Junctional rhythm, and Junctional tachycardia.
    • It is used for treatment of supraventricular tachycardias.
    • It is needed for the chaotic rhythm of ventricular fibrillation and is also used for pulseless ventricular tachycardia.
    • Rhythm originating at or above AV node constitutes supraventricular tachycardia (SVT).
  • Carotid Sinus Syncope and Massage

    • It is sometimes useful for differentiating supraventricular tachycardia (SVT) from ventricular tachycardia.
  • Signs and Symptoms of Shock

    • This leads to a rapid, weak pulse due to decreased blood flow combined with tachycardia, cool, clammy skin due to vasoconstriction, and stimulation of vasoconstriction.
  • Proprioceptor Regulation of Breathing

    • Its stimulation causes a short-term increase in resting heart rate, which is called tachycardia.
    • When this process is cyclical it is called a sinus arrhythmia, which is a generally normal physiological phenomenon in which there is short-term tachycardia during inspiration.
  • Cardiac Cycle

    • However, the reference range is normally between 60 bpm (if less it is termed bradycardia) and 100 bpm (if greater it is termed tachycardia).
  • Hantavirus

    • The hypotensive phase occurs when the blood platelet levels drop, and can lead to tachycardia and hypoxemia.
  • Cardiopulmonary Resuscitation (CPR)

    • Defibrillation is only effective for certain heart rhythms, namely ventricular fibrillation or pulseless ventricular tachycardia, rather than asystole or pulseless electrical activity.
  • Types of Shock

    • Typical symptoms include a rapid, weak pulse due to decreased blood flow combined with tachycardia, cool, clammy skin, and rapid and shallow breathing.
  • The Resistance Reaction

    • The result is: increased muscular tonus, increased blood pressure due to peripheral vasoconstriction and tachycardia, and increased glucose in blood.
  • Chemical Composition of Bone

    • Cardiac complications include arrhythmias (ventricular tachycardia), decreased response to epinephrine; both lead to hypotension (low blood pressure).
