  1. Cochlear implant

  2. Pacemaker

  3. Insulin pump

  4. Deep brain stimulator
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pacemakers are implantable devices that regulate heart rhythm by sending electrical pulses to the heart, ensuring a regular and consistent heartbeat.

Multiple choice

What is the main purpose of implantable cardioverter-defibrillators (ICDs)?

  1. Regulating heart rhythm

  2. Measuring blood pressure

  3. Monitoring blood glucose levels

  4. Detecting heart murmurs
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Implantable cardioverter-defibrillators (ICDs) are devices that monitor heart rhythm and deliver electrical shocks to correct abnormal heart rhythms, preventing sudden cardiac death.
