supraventricular tachycardia
(noun)
Any rapid heart rhythm originating at or above the atrioventricular node.
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).
-
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).
-
Sickle-Cell Disease
- Aplastic crises are acute worsenings of the patient's baseline anemia producing pallor, tachycardia, and fatigue.
