Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
However, if a patient is confirmed to be in pulseless ventricular tachycardia "v-tach" or ventricular fibrillation "v-fib", then a shock is delivered immediately upon connection of the pads. In this application, electrical cardioversion is more properly termed defibrillation.
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
When V-tach is sustained (lasts for at least 30 seconds), inadequate blood flow to heart tissue can lead to cardiac arrest. [ 63 ] Bradyarrhythmias occur following dissociation of spontaneous electrical conduction and the mechanical function of the heart resulting in pulseless electrical activity (PEA) or through complete absence of electrical ...
Torsades de pointes, torsade de pointes or torsades des pointes (TdP; also called torsades) (/ t ɔːr ˌ s ɑː d d ə ˈ p w æ̃ t /, [2] French: [tɔʁsad də pwɛ̃t̪], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.
There are multiple factors during cardiopulmonary resuscitation (CPR) and defibrillation that are associated with success of achieving return of spontaneous circulation. . One of the factors in CPR is the chest compression fraction, which is a measure of how much time during cardiac arrest are chest compressions perfor
