  2. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]

  3. Ventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Ventricular_tachycardia

    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.

    Having V-tach is really dangerous and can develop into another dangerous rhythm Ventricular fibrillation, both of these require immediate medical attention. VT is treated with cardioversion, either drug cardioversion or electrical cardioversion. Drug cardioversion involves a drug treatment that aims to lower the heart rate back to a normal rhythm.

  5. Defibrillation - Wikipedia

    en.wikipedia.org/wiki/Defibrillation

    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.

  6. Cardiac monitoring - Wikipedia

    en.wikipedia.org/wiki/Cardiac_monitoring

    An example of automatic monitoring is the transtelephonic cardiac event monitor. This monitor contacts ECG technicians, via telephone, on a regular basis, transmitting ECG rhythms for ongoing monitoring. The transtelephonic cardiac event monitor can normally store approximately five "cardiac events" usually lasting 30–60 seconds.

  7. Primary ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Primary_ventricular...

    12-lead ECG of ventricular fibrillation. Primary ventricular fibrillation (PVF) is an unpredictable [1] and potentially fatal arrhythmia occurring during the acute phase of a myocardial infarction leading to immediate collapse and, if left untreated, leads to sudden cardiac death within minutes.

  8. Tachycardia-induced cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-induced_cardio...

    electrocardiography (EKG) Continuous cardiac rhythm monitoring (e.g. Holter monitor) echocardiography; Radionuclide imaging; Endomyocardial biopsy; Cardiac magnetic resonance imaging (CMR) N-terminal pro-B-type natriuretic peptide (NT-pro BNP) Cardiac rhythm monitors can be used to diagnose tachyarrhythmias. The most common modality used is an EKG.

  9. Cardioversion - Wikipedia

    en.wikipedia.org/wiki/Cardioversion

    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.
