2. Implantable cardioverter-defibrillator - Wikipedia

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

   More modern devices have software designed to attempt a discrimination between ventricular fibrillation and ventricular tachycardia (VT), and may try to pace the heart faster than its intrinsic rate in the case of VT, to try to break the tachycardia before it progresses to ventricular fibrillation. This is known as overdrive pacing, or anti ...

3. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   The DAVID trials [24] have shown that unnecessary pacing of the right ventricle can exacerbate heart failure and increases the incidence of atrial fibrillation. The newer dual-chamber devices can keep the amount of right ventricle pacing to a minimum and thus prevent worsening of the heart disease.

4. Subcutaneous implantable defibrillator - Wikipedia

   en.wikipedia.org/wiki/Subcutaneous_implantable...

   S-ICD lead and generator position. Subcutaneous implantable cardioverter defibrillator, or S-ICD, is an implantable medical device for detecting and terminating ventricular tachycardia and ventricular fibrillation in patients at risk of sudden cardiac arrest. [1]

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 pacemaker - Wikipedia

   en.wikipedia.org/wiki/Cardiac_pacemaker

   An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

7. Implantable loop recorder - Wikipedia

   en.wikipedia.org/wiki/Implantable_loop_recorder

   An implantable loop recorder (ILR), also known as an insertable cardiac monitor (ICM), is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period.
