What is the primary role of the pulse generator in a cardiac pacemaker system?

For a patient experiencing a 2nd degree, type 2 AV block or a 3rd degree AV block complicating an inferior MI, what is the most appropriate initial intervention?

What is the key differentiating factor between temporary and permanent pacing methods?

In the context of cardiac pacing, what is the significance of 'sensitivity'?

What is the underlying mechanism by which an implantable cardioverter defibrillator (ICD) terminates ventricular tachycardia?

Which of the following best describes the primary distinction between 'demand' and 'fixed rate' pacing modes?

What is the critical implication of 'loss of capture' in a patient with a permanent pacemaker?

What is the fundamental physiological principle underlying the function of an AV sequential pacemaker?

Which of the following statements accurately reflects a key advantage of rate-responsive pacemakers?

In the context of cardiac pacing, how would a pacemaker be defined if it is programmed to sense both the atrium and ventricle, and is capable of both triggering and inhibiting its response based on sensed events?

What is the most appropriate immediate nursing intervention for a patient experiencing electrical storm (multiple ICD firings) caused by polymorphic ventricular tachycardia?

Which of the following represents a primary indication for implantation of a cardioverter-defibrillator (ICD)?

In the assessment of a patient with a pacemaker, what ECG finding confirms appropriate atrial pacing?

A patient with a permanent pacemaker is scheduled for an MRI. What consideration is most important?

What is the most critical nursing action to prevent microshock in a patient with a temporary transvenous pacemaker?

What physiological event is directly represented by the 'artifact or spike' seen on an ECG tracing of a patient with a cardiac pacemaker?

What is the primary role of the 'lead system' in the context of cardiac pacing?

Following implantation of a permanent pacemaker, a patient reports persistent discomfort and limited range of motion in the affected arm. What complication should the nurse suspect?

What is the primary advantage of using temporary transcutaneous pacing in an emergency?

A patient with a newly implanted ICD receives a shock. In what order are these nursing actions needed? 1. Assess the patient’s level of consciousness, airway, and breathing. 2. Document the event and ICD response in the patient’s record. 3. Obtain a 12-lead ECG. 4. Notify the physician.

What is the most appropriate sensor to use to enable 'rate responsiveness' in a permanent pacemaker, to best mimic natural physiological heart rate changes during exercise?

While caring for a patient with a temporary transvenous pacemaker, the nurse observes frequent premature ventricular contractions (PVCs). How should the nurse initially respond?

Which ECG characteristic is most indicative of oversensing in a patient with a ventricular pacemaker?

Which statement best describes the 'inhibit' function in a modern cardiac pacemaker?

Which nursing intervention is paramount in reducing infection risk following permanent pacemaker implantation?

A patient with a history of ventricular fibrillation is being evaluated for an implantable cardioverter defibrillator (ICD). Which diagnostic finding would be the strongest indication for ICD placement?

What key educational point should a nurse emphasize when teaching a patient about living with an ICD?

In the context of cardiac pacing, what does the term 'capture' specifically refer to?

A patient with a permanent pacemaker develops pacemaker-mediated tachycardia (PMT). What is the underlying mechanism?

What is the primary reason for using bipolar pacing leads over unipolar leads?

A patient is scheduled for cardioversion. Which action is essential to ensure patient safety?

In a patient experiencing AV block after an inferior MI, which pacemaker configuration would most closely mimic normal cardiac conduction physiology?

What is the most important consideration when providing discharge teaching to a patient with a new permanent pacemaker regarding cell phone use?

What type of arrhythmia is most likely indicated by this ECG of an ICD patient?

When preparing a patient for external (transcutaneous) pacing, what is the most important initial assessment by the nurse?

What best explains the occurrence of oversensing in pacemakers?
