NCI: A ventricular tachyarrhythmia characterized electrocardiographically by smooth undulating waves with QRS complexes merged with T waves, a rate of approximately 250 per minute.,MSH: A potentially lethal cardiac arrhythmia characterized by an extremely rapid, hemodynamically unstable ventricular tachycardia (150-300 beats/min) with a large oscillating sine-wave appearance. If untreated, ventricular flutter typically progresses to VENTRICULAR FIBRILLATION.,NCI: A ventricular tachyarrhythmia characterized by a high ventricular rate (180 and 250 beats per minute) with a regular rhythm. The electrocardiogram shows large oscillating sine wave-like complexes occurring as a result of QRS complexes and T waves being merged. The P wave is not visible.
