I Cannot Provide an ECG Image

I'm unable to display or provide actual ECG images as I don't have the capability to generate, retrieve, or show pictures. However, I can describe the characteristic ECG features of ventricular tachycardia based on the authoritative guidelines provided.

Key ECG Features of Ventricular Tachycardia

According to the 2015 ACC/AHA/HRS Guidelines 1, ventricular tachycardia demonstrates the following diagnostic ECG characteristics:

Definitive Diagnostic Criteria

  • Wide QRS complex: Duration >120 ms (this is the hallmark feature)
  • AV dissociation: Ventricular rate faster than atrial rate - this is pathognomonic for VT 1
  • Fusion complexes: Representing dissociation of supraventricular impulses from ventricular rhythm - diagnostic of VT 1

Highly Suggestive Features

Brugada Criteria (examining leads V1-V6):

  • Absence of any R-S complexes in precordial leads
  • R-S interval >100 ms (from onset of R wave to nadir of S wave) in any precordial lead 1

Vereckei Algorithm (examining lead aVR):

  • Presence of initial R wave
  • Initial R or Q wave >40 ms
  • Notch on descending limb at onset of predominantly negative QRS 1

Additional Features:

  • Concordance: All precordial QRS complexes either positive or negative 1
  • R-wave peak time ≥50 ms in lead II 1

Neonatal/Pediatric Considerations

In infants, per the European Society of Cardiology guidelines 2:

  • QRS may be only slightly prolonged (<0.08 s) but with different morphology from sinus rhythm
  • Rate typically 200-500 bpm
  • May show slight R-R interval variation
  • Can have sinus P waves unrelated to VT (AV dissociation), retrograde P waves, or no visible P waves

Critical Clinical Point

The failure to correctly identify VT can be potentially life-threatening, particularly if misdiagnosis results 1. When evaluating wide-complex tachycardia, always assume VT until proven otherwise in the acute setting.

To view actual ECG images of ventricular tachycardia, I recommend:

  • Consulting the original 2015 ACC/AHA/HRS guideline document (Figure 1 specifically shows VT)
  • Medical textbooks with ECG atlases
  • Online medical education resources with verified ECG libraries
