  2. 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.

  3. Idioventricular rhythm - Wikipedia

    en.wikipedia.org/wiki/Idioventricular_rhythm

    An idioventricular rhythm is a cardiac rhythm characterized by a rate of <50 beats per minute (bpm), absence of conducted P waves and widening of the QRS complex. [1] In cases where the heart rate is between 50 and 110 bpm, it is known as accelerated idioventricular rhythm and ventricular tachycardia if the rate exceeds 120 bpm.

  4. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    Right ventricular outflow tract tachycardia originates from the outflow tract of the right ventricle or the tricuspid annulus. As it arises from the right ventricle, the impulse spreads inferiorly from beneath the pulmonary valve, and there right axis deviation.

  5. Catecholaminergic polymorphic ventricular tachycardia

    en.wikipedia.org/wiki/Catecholaminergic...

    Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited genetic disorder that predisposes those affected to potentially life-threatening abnormal heart rhythms or arrhythmias. The arrhythmias seen in CPVT typically occur during exercise or at times of emotional stress, and classically take the form of bidirectional ...

  6. Re-entry ventricular arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Re-entry_ventricular...

    Re-entry ventricular arrhythmia is a type of paroxysmal tachycardia occurring in the ventricle where the cause of the arrhythmia is due to the electric signal not completing the normal circuit, but rather an alternative circuit looping back upon itself. [1] There develops a self-perpetuating rapid and abnormal activation.

  7. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Ventricular fibrillation and ventricular tachycardia are most commonly recorded. [14] However, as many incidents of cardiac arrest occur out-of-hospital or when a person is not having their cardiac activity monitored, it is difficult to identify the specific mechanism in each case.
