Evanescent RVH: LPHB

Report:

Atrial fibrillation, aver. Response 100/min

Right axis deviation +140o

Right bundle branch block

QRV1

Right ventricular hypertrophy or left posterior hemiblock

Comment:

This case illustrates the problem of assigning the origin of RAD. It could be either RVH or LPHB. A subsequent trace, however, showed both LPHB and RBBB to be rate-dependent (Fig 281a). The normal complexes in-between rule out RVH.

281a. No question of RVH now.
