Ventricular flutter

This is another form of VT which is characteristic for its rate and appearance

• Very rapid, regular, wide complex tachycardia
• Rate 300 b.p.m. or more
• Sine wave morphology
• No distinction between QRS and T wave

Features of this ECG

• Ventricular flutter, rate 300-340 b.p.m. left axis deviation
• Characteristic morphology
• Sine wave
• No distinction between QRS and T wave
• It is unclear where one complex finishes and the other starts
• It looks the same if viewed upside down

Clinical note

• Ventricular flutter is usually short lived, associated with a marked fall in blood pressure and progresses to ventricular fibrillation
• This man was started on amiodarone
