  2. Impedance cardiography - Wikipedia

    en.wikipedia.org/wiki/Impedance_cardiography

    Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the impedance changes caused by a high-frequency, low ...

  3. 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.

  4. Implantable cardioverter-defibrillator - Wikipedia

    en.wikipedia.org/wiki/Implantable_cardioverter...

    A normal chest X-ray after placement of an ICD, showing the ICD generator in the upper left chest and the ICD lead in the right ventricle of the heart. Note the 2 opaque coils along the ICD lead. The process of implantation of an ICD system is similar to implantation of an artificial pacemaker. In fact, ICDs are composed of an ICD generator and ...

  5. Impedance threshold device - Wikipedia

    en.wikipedia.org/wiki/Impedance_threshold_device

    An inspiratory impedance threshold device is a valve used in cardiopulmonary resuscitation (CPR) to decrease intrathoracic pressure and improve venous return to the heart. The valve is a part of a mask or other breathing device such as an endotracheal tube , and may open at high or low pressures (called "cracking pressures") [ citation needed ]

  6. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Leads are broken down into three types: limb; augmented limb; and precordial or chest. The 12-lead ECG has a total of three limb leads and three augmented limb leads arranged like spokes of a wheel in the coronal plane (vertical), and six precordial leads or chest leads that lie on the perpendicular transverse plane (horizontal). [33]

  7. Transcutaneous pacing - Wikipedia

    en.wikipedia.org/wiki/Transcutaneous_pacing

    The pads are then attached to a monitor/defibrillator, a heart rate is selected, and current (measured in milliamps) is increased until electrical capture (characterized by a wide QRS complex with tall, broad T wave on the ECG) is obtained, with a corresponding pulse. Pacing artifact on the ECG and severe muscle twitching may make this ...

  8. Wearable cardioverter defibrillator - Wikipedia

    en.wikipedia.org/wiki/Wearable_cardioverter...

    A wearable cardioverter defibrillator (WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care.

  9. Automated external defibrillator - Wikipedia

    en.wikipedia.org/wiki/Automated_external...

    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 ...
