Pacemakers and Defibrillators: Difference between the two & importance in cardiology Heart arrhythmias are frequently treated using pacemakers and defibrillators, although they work quite differently and have various risks. When a person's heart has ceased beating normally or is dangerously aberrant, a defibrillator is used to shock the heart back into rhythm. With the use of defibrillators, an electric current is passed through the chest wall and into the heart muscle, resulting in quick contractions that can resume a regular beating. An electrical impulse is sent by a pacemaker implant to instruct the heart when to beat more quickly or slowly. The most crucial muscle in the body is the heart, which keeps us alive. Technology is available to assist when the heart can't keep up due to illness, damage, or other problems. Pacemakers and defibrillators are two of the most often used equipment connected to heart attacks, heart disease, and other heart diseases.
Defibrillators vs Pacemakers Defibrillators are also known as ICDs. Anyone who has cardiomyopathy, a history of cardiac arrest, significantly compromised heart function, or hereditary illnesses such as Long QT syndrome, ARVC, cardiac sarcoidosis, etc. Typically, ICDs are inserted beneath the collarbone. An ICD is comparable in size to a pager and bigger than a pacemaker. Defibrillators are used to treat fast heartbeats known as tachycardia, but they can also work as pacemakers to treat problems with weaker or slower heartbeats.
