How is the cardiac rhythm of atrial flutter characterized?

• A. Stable with low heart rates
• B. Hazardous, as the ventricular rate may suddenly increase
• C. Unchanged with medication
• D. Consistently low output

Answer: (B)

The cardiac rhythm of atrial flutter is characterized by a rapid and regular atrial contraction, which can lead to varying ventricular rates. The phenomenon associated with atrial flutter is that the conduction through the AV node can sometimes allow for a very quick ventricular response, particularly if there is a change in the autonomic tone, or if the patient is exposed to certain conditions or medications that alter AV conduction. This can result in a sudden increase in ventricular rate, which may lead to hemodynamic instability and can be hazardous. Therefore, recognizing the potential for a sudden rise in the ventricular rate is critical in managing patients with atrial flutter because it can cause complications such as palpitations, chest pain, or even more severe cardiac events.
