Final answer:
Devices such as artificial pacemakers and automated external defibrillators (AEDs) are used to correct and manage heart dysrhythmias. Pacemakers are implanted and can provide tailored electrical impulses to the heart, while AEDs can deliver a necessary electric shock in emergencies to restore normal heart rhythm.
Step-by-step explanation:
The placement of a device used to correct and manage heart dysrhythmias is within the body. A cardiologist can implant an artificial pacemaker, which delivers electrical impulses to the heart muscle ensuring continuous and effective pumping of blood. These pacemakers can function on-demand or continuously and are programmable. In some situations, portable automated external defibrillators (AEDs) are used for emergency interventions for arrhythmias such as ventricular fibrillation, delivering a substantial electric shock to restore normal heart rhythm.
In severe cases, medical professionals might administer a large shock in a controlled environment via cardioversion or defibrillation. For support during physical activities, pacemakers with motion and breathing sensors adjust the heart rate accordingly. It's now common for public places to house AEDs, which are user-friendly and guide rescuers through the resuscitation process, sometimes following CPR.
