What is a potential complication of untreated atrial tachycardia?

• A. Severe dehydration
• B. Heart failure and stroke risk
• C. Acute kidney failure
• D. Myocardial ischemia

Answer: (B)

Untreated atrial tachycardia can lead to significant complications, primarily heart failure and an increased risk of stroke. Atrial tachycardia causes the heart to beat at a faster rate, which can compromise its ability to effectively pump blood. Over time, this inefficiency can lead to heart failure, characterized by symptoms like fatigue, shortness of breath, and fluid retention. Moreover, atrial tachycardia can contribute to the development of blood clots in the heart's left atrium due to turbulent blood flow. If these clots dislodge, they can travel to the brain, resulting in a stroke. Thus, the connection between uncontrolled atrial tachycardia and these serious complications makes it critical to manage the condition appropriately to reduce such risks. In contrast, complications such as severe dehydration, acute kidney failure, or myocardial ischemia are less directly associated with atrial tachycardia. While these conditions can occur in various clinical contexts, they do not represent the primary concerns when specifically considering the implications of untreated atrial tachycardia.
