  2. Defibrillation threshold - Wikipedia

    en.wikipedia.org/wiki/Defibrillation_threshold

    Defibrillation threshold indicates the minimum amount of energy needed to return normal rhythm to a heart that is beating in a cardiac dysrhythmia.Typical examples are the minimum amount of energy, expressed in joules, delivered by external defibrillator paddles or pads, required to break atrial fibrillation and restore normal sinus rhythm.

  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.

  4. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    Sinus tachycardia is another regular rhythm however the ventricular rate is quicker, between 100 - 160 bpm, with a normal PR interval and normal QRS complex. Sinus arrhythmia is an irregular rhythm with a ventricular rate of 60 - 100 normally, however a slow rhythm can be distinguished when the rate is less than 60, the PR interval and QRS ...

  5. Tachycardia - Wikipedia

    en.wikipedia.org/wiki/Tachycardia

    Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [ 1 ]

    en.wikipedia.org/.../Ventricular_tachycardia

    But ventricular tachycardia’s different than, say, a fast heart rate from exercising, which is called as “sinus tachycardia”. Normally, the electrical signals that generates each heart beat starts in the right atrium, at the sinus node, also known as the sinoatrial node or the SA node, if the rate goes over 100 bpm and originates in the ...

  7. Automatic tachycardia - Wikipedia

    en.wikipedia.org/wiki/Automatic_tachycardia

    Ectopic atrial tachycardia (EAT), also known as automatic atrial tachycardia, is an arrhythmia caused by both atria with abnormally fast atrial rates. [12] The ectopic focus's firing rate is quicker than that of the sinus node, and it overrides normal sinus node activity. Heart rates in children and adolescents can range from 130 to 210 beats ...

  8. Tachycardia-induced cardiomyopathy - Wikipedia

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

    Some studies have noted the incidence of TIC in adults with irregular heart rhythms to range from 8% to 34%. [5] Other studies of patients with atrial fibrillation and left ventricular dysfunction estimate that 25–50% of these study participants have some degree of TIC. [6] TIC has been reported in all age groups. [6]

  9. Atrial tachycardia - Wikipedia

    en.wikipedia.org/wiki/Atrial_tachycardia

    The ventricular rate is controllable with the use of beta blockers or calcium channel blockers. If atrial tachyarrhythmia persists and the patient is symptomatic, the patient may benefit from class IA, IC, or class III antiarrhythmics. Catheter ablation of focal atrial tachycardia may be appropriate in patients failing medical therapy. [2]
