What complication could arise from not using an external pacemaker when indicated?

• A. Rapid heartbeat
• B. Myocardial infarction
• C. Prolonged symptomatic bradycardia
• D. Unexplained joint pain

Answer: (C)

Failing to utilize an external pacemaker when indicated can lead to prolonged symptomatic bradycardia. Bradycardia refers to a slower than normal heart rate, which can result in insufficient blood flow to vital organs. This condition may lead to a variety of symptoms, including fatigue, dizziness, syncope (fainting), and more severe consequences if not addressed promptly. When an external pacemaker is necessary, it assists in maintaining an adequate heart rate and rhythm, thereby ensuring appropriate cardiac output. If this intervention is not applied, the heart may continue to beat inadequately, leading to sustained low blood flow for an extended period. This situation can exacerbate the symptoms and may potentially cause serious complications, such as congestive heart failure or shock. The other options, while they are related to cardiovascular conditions, do not directly result from the failure to use an external pacemaker in cases of symptomatic bradycardia. Rapid heartbeat, myocardial infarction, and unexplained joint pain are distinct issues that stem from different underlying conditions and do not connect as directly to the consequences of untreated bradycardia.
