Malignant ventricular tachycardia can mimic benign atrial flutter on electrocardiograms (ECGs). Careful comparison of QRS complex morphology across all leads is crucial for accurate diagnosis.

Area of Science:

  • Cardiology
  • Medical Diagnostics

Background:

  • Pseudoatrial flutter is typically associated with benign causes.
  • Distinguishing between benign and malignant arrhythmias is critical for patient management.

Observation:

  • An 82-year-old patient presented with symptoms suggestive of atrial flutter.
  • Electrocardiogram (ECG) revealed an electrical artifact that mimicked atrial flutter.

Findings:

  • The observed arrhythmia was identified as ventricular tachycardia, a malignant condition.
  • Morphological comparison of QRS complexes between the rhythm strip and lead II confirmed ventricular origin.

Implications:

  • This case highlights the potential for malignant arrhythmias to present as benign ones.
