I49.02

Clinical Information

• 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.

• 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.

• A ventricular tachyarrhythmia characterized electrocardiographically by smooth undulating waves with qrs complexes merged with t waves, a rate of approximately 250 per minute.
