ARVC ARVD epsilon ecg

Diagnosis- Arrhythmogenic RV dysplasia

Pointers-

1. Epsilon wave

2. T inversion in v 1 to v3

3. Positive QRS in v1 (the classical RBBB pattern is not present in this ECG)

Comments are welcome.

WPW preexcitation accessory pathway left lateral ecg

Diagnosis- pre-excitation with left lateral accessory pathway.

Pointers-

1. Short PR interval and delta wave – pre-excitation.

2. Positive delta in v1- left sided pathway.

3. Positive delta in avF- left lateral pathway.

right ventricular outflow tract ventricular tachycardia ecg image

Diagnosis- RVOT ventricular tachycardia (RVOT – Right ventricular outflow tract)

Pointers-

1. The first two beats are wide complex. Then sinus rhythm is seen. Wide complex tachycardia recurs after 5 sinus beats. The last beat is a sinus beat.

2. P waves dissociated from the QRS can be seen in the bottom rhythm strip (lead II) in the second group of wide complex beats- so the tachycardia is VT.

3. LBBB pattern + inferior axis. This is the characteristic pattern in RVOT VT. Inferior axis is inferred from the first two wide complex beats seen in leads I, II and III.

Belhassen ventricular tachycardia ecg image

Diagnosis- Belhassen’s tachycardia (posterior fascicular ventricular tachycardia)

Pointers-

1. QRS is wide, but not very wide, the width being 120 msec. This makes it difficult to differentiate whether this is VT or SVT.

2. Capture beat indicating that it is VT, not SVT.

3. RBBB + left axis deviation, the characteristic pattern in Belhassen’s tachycardia.

arm lead reversal ecg image

Diagnosis- Arm lead reversal.

Pointers-

1. Precordial leads are normal.

2. In limb leads, QRS axis is 150 degrees and P axis is 120 degrees.

  • Observations-
    • Absent P waves
    • QRS complexes at irregular intervals
    • Some QRS complexes are RBBB while others are LBBB (note that the lead is v1)
  • Diagnosis-
    • Best diagnosis- Atrial fibrillation with alternating bundle branch blocks
    • Second best diagnosis- Atrial fibrillation with baseline wide QRS due to non-specific conduction defect and occasional tachycardia induced RBBB aberrancy.
