1. The pacemaker monitors heart rate. If the heart rate is normal, it does not send an impulse.

2. If it detects a slowing of the heart rate (bradycardia), it sends electrical impulses to the heart to speed up.

1. Internal cardioverter defibrillators (ICD) are used to treat harmful tachyarrhythmias such as ventricular tachycardia.

2. ICD monitors blood pressure. If it's rapid, it delivers an electrical shock (cardioversion / defibrillation).

The difference between a pacemaker and an ICD is that a pacemaker treats bradycardia and sends electrical impulses while an ICD treats tachycardia and sends an electrical shock.

Which of the following should not be used on patients with a pacemaker or ICD?

The most common use for an implantable cardioverter defibrillator is:

The portion of the pacemaker that contains the electronic circuitry and powers the device is the:

All of the following are symptoms of an individual suffering from a pacemaker malfunction except one. Which one is the exception?

The most important vital sign to monitor on a patient suspected of having a pacemaker malfunction is the:

Local anesthetics with vasoconstrictors should be used with caution on patients with pacemakers and ICD's.

The factor that causes the greatest risk of malfunction with pacemakers or ICDs is:

The first step in the treatment of suspected pacemaker malfunction is to:

Select signs and symptoms of pacemaker malfunction.

Select the signs and symptoms of an ICD malfunction.

Dental procedures are considered low risk and most dental equipment is safe for pacemakers and ICD.

Select the unsafe procedures with older models of pacemakers or ICD's.

Radiographs, hand pieces (high speed / low speed), and curing lights are considered unsafe procedures with older models of pacemakers or ICD's.

This is the mixing up of bacteria in the mouth that can travel through the blood stream

Which is NOT a risk factor for taking a pre-medication?

Which is NOT a risk factor for Infective Endocarditis.

Bacteremia is less likely caused by frequent exposure to bacteria as opposed to a one time exposure

According to the ADA, the clinical recommendation for patients with prosthetic joint implants, prophylactic antibiotics are not recommended prior to dental procedures to prevent prosthetic joint infection.

When is it recommended to prescribe an antibiotic for a patient that has a prosthetic joint replacement?

Select all that apply.

There are potential harms of antibiotics including risk for anaphylaxis, antibiotic resistance, and opportunistic infections.
