Question

identify this rhythm:

artifact
ventricular tachycardia (monomorphic tachycardia)
ventricular fibrillation
torsades de pointes (polymorphic tachycardia)

Explanation:

Analyze the ECG strip characteristics

The ECG strip shows a rapid, irregular ventricular rhythm with QRS complexes that continuously change in shape, amplitude, and direction. The axis of the QRS complexes appears to twist around the isoelectric baseline, showing a characteristic spindle-like or sinusoidal pattern.

Identify the specific arrhythmia

This twisting of the QRS complexes around the baseline is the hallmark of Torsades de Pointes, which is a specific form of polymorphic ventricular tachycardia.

Correlate with the given options

The observed pattern matches the option "Torsades de Pointes (polymorphic tachycardia)".

Answer:

• Artifact
• Ventricular tachycardia (monomorphic tachycardia)
• Ventricular fibrillation
• Torsades de Pointes (polymorphic tachycardia) (Correct answer)
