Final answer:
Tachycardia is harmful to patients with heart problems due to increased workload on the heart, decreased blood flow to the heart, and the potential to cause irregular heart rhythms. The correct answer to the student's question is 'all of the above'.
Step-by-step explanation:
Tachycardia and Cardiac Problems
Tachycardia can indeed be detrimental to a patient experiencing a cardiac problem because it involves an increased heart rate that can have various negative effects on the heart's function. There are several reasons tachycardia can be harmful, including:
Increased workload on the heart: The heart has to pump faster, which can lead to overexertion.
Decreased blood flow to the heart: Too rapid of a heart rhythm can diminish coronary blood flow, leading to insufficient oxygen delivery to heart tissue.
Irregular heart rhythms: Tachycardia can disrupt the normal rhythm of the heart, potentially leading to arrhythmias.
So, when considering tachycardia and its impact on a patient with a heart problem, the correct answer would be all of the above. Each of these factors contributes to why tachycardia needs careful evaluation and management in the context of heart health.
