How does ventricular flutter primarily present on an ECG?

• A. Irregular and chaotic waveforms
• B. Smooth sine waves with similar amplitude
• C. Uniform spike and dip patterns
• D. Slow, deep, and infrequent heart beats

Answer: (B)

Ventricular flutter is characterized on an ECG by very specific waveforms that appear as smooth sine waves with uniform amplitude. This rhythm occurs due to a rapid, continuous circuit of reentry within the ventricles, resulting in a high rate of contractions. The sine wave appearance indicates that the electrical activity is synchronized in such a way that the heart muscle is depolarizing and repolarizing continuously, leading to the characteristic pattern. The evenly spaced nature of the waves suggests a consistent rhythm, which differentiates it from the chaotic patterns of other arrhythmias. In contrast, the other choices do not accurately describe the structured nature of ventricular flutter. Irregular waveforms and varying amplitudes point towards other arrhythmias, while slow and infrequent heartbeats suggest conditions such as bradycardia, which are not typical of ventricular flutter.
