How are “F-waves” characterized in atrial flutter?

• A. Regular, rounded peaks
• B. Sawtooth-like deflections
• C. Flat, horizontal lines
• D. Irregular, jagged spikes

Answer: (B)

F-waves in atrial flutter are characterized by a distinct sawtooth-like appearance. This pattern, often referred to as "sawtooth" or "F-waves," is primarily observed in the inferior leads of an electrocardiogram. The morphology of these waves represents the reentrant nature of atrial flutter, where the electrical impulses circulate around a circuit within the atria, leading to a rapid and organized atrial activity. The sawtooth pattern is particularly evident in leads II, III, and aVF, where the peaks and troughs resemble the teeth of a saw. This unique appearance of the F-waves in atrial flutter assists clinicians and electrophysiologists in identifying the condition accurately, allowing for appropriate management and treatment strategies. The distinct characteristics of F-waves provide essential information that differentiates atrial flutter from other atrial arrhythmias, such as atrial fibrillation or atrial tachycardia, which tend to have different waveforms.
