What does the presence of paroxysmal supraventricular tachycardia indicate?

• A. Generally benign atrial finding
• B. Potentially dangerous atrial finding
• C. Lethal ventricular finding
• D. Generally benign AV block

Answer: (B)

The presence of paroxysmal supraventricular tachycardia (PSVT) suggests a potentially dangerous atrial finding because it often involves episodes of rapid heart rate originating from the atria or the atrioventricular (AV) node. Although PSVT can be benign in some individuals, particularly those without underlying heart disease, it has the potential to lead to more serious complications for others, especially in patients with existing cardiac conditions.

PSVT can result in symptoms such as palpitations, dizziness, or chest discomfort, which may indicate underlying heart issues. Additionally, if the rapid heart rate is sustained or if it occurs frequently, it may lead to hemodynamic instability and necessitate medical intervention. Therefore, while PSVT can sometimes be self-limiting and not always hazardous, it is still associated with risks that necessitate careful monitoring and management, particularly in patients with a history of heart disease.
