What device is used to convert ineffective heart rhythm back into normal rhythm?

Defibrillator
Pacemaker
ECG monitor
Stethoscope

The correct answer is: Defibrillator

The device used to convert an ineffective heart rhythm back into a normal rhythm is a defibrillator. Defibrillators deliver a dose of electric current (or shock) to the heart, which can help restore a normal rhythm in cases of life-threatening arrhythmias such as ventricular fibrillation or pulseless tachycardia. This process can be crucial in emergency situations where the heart is unable to circulate blood effectively due to these irregular rhythms, thus potentially saving a patient's life. Other devices mentioned have different functions. A pacemaker is designed to regulate the heart's rhythm by delivering electrical impulses to stimulate the heart to beat at a normal rate, particularly in cases of slow heart rhythms. An ECG monitor is utilized for observing the electrical activity of the heart, helping to diagnose arrhythmias but not correct them. A stethoscope is a tool for auscultation, used to listen to heart sounds but does not provide any corrective action for heart rhythms.
