What is a major consequence of failure to pace?

• A. The pacemaker fires consistently at set parameters
• B. The pacemaker does not fire when needed, leading to decreased heart rate
• C. The pacemaker only fires irregularly
• D. The patient experiences increased heart rate

Answer: (B)

A major consequence of failure to pace is that the pacemaker does not fire when needed, leading to decreased heart rate. In cases where a pacemaker is implanted to regulate heart rhythms, it is essential that it functions correctly to send electrical impulses to the heart at appropriate intervals. If the pacemaker fails to deliver these impulses, it can result in a significantly lowered heart rate, which can compromise the heart's ability to pump blood effectively throughout the body. This situation leaves the patient vulnerable to symptoms such as dizziness, fatigue, and even fainting, due to the insufficient blood flow caused by the decreased heart rate. Maintaining proper pacing is critical for patients relying on pacemakers to ensure that their heart maintains a safe and effective rhythm.
