  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. Precordial thump - Wikipedia

    en.wikipedia.org/wiki/Precordial_thump

    Precordial thump is a medical procedure used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia under certain conditions. The procedure has a very low success rate, but may be used in those with witnessed, monitored onset of one of the "shockable" cardiac rhythms if a defibrillator is not immediately available.

    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. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Heart rate related - Palpitations associated with arrhythmias; In particular, the examiner should look for the following in the physical examination, as these are frequent findings at the time of admission: [2] [5] [6] [8] Vital signs may reveal hypotension, tachycardia, tachypnea, or low oxygen saturation.

  6. Junctional rhythm - Wikipedia

    en.wikipedia.org/wiki/Junctional_rhythm

    The first finding is that junctional rhythms are regular rhythms. This means that the time interval between beats stays constant. The next normal finding is a normal QRS. Since the impulse still travels down the bundle of His, the QRS will not be wide. Junctional rhythms can present with either bradycardia, a normal heart rate, or tachycardia. [9]

  7. Defibrillation threshold - Wikipedia

    en.wikipedia.org/wiki/Defibrillation_threshold

    The defibrillation threshold ranking in these settings, from lowest to highest, would be, in order, ventricular tachycardia, atrial flutter, atrial fibrillation, ventricular fibrillation. The highest amount of energy that an external defibrillator can deliver at the present time is 360 joules biphasic.

  8. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Rates of survival are better in those who had someone witness their collapse, received bystander CPR, and/or had either V-fib or V-tach when assessed. [145] Survival among those with V-fib or V-tach is 15 to 23%. [145] Women are more likely to survive cardiac arrest and leave the hospital than men. [146]

  9. Ejection fraction - Wikipedia

    en.wikipedia.org/wiki/Ejection_fraction

    Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
