Figure 1
A) Baseline twelve lead ECG showing atrial flutter with 2:1 block,
occasional premature ventricular contraction and LBBB prior to
cardioversion. Black arrows show atrial flutter waves on ECG rhythm
strip II. ECG is of low voltage. Diffuse increase in LV wall thickness
is seen in parasternal long axis (B), short axis (C) and apical 4
chamber views (D). TTE LV wall thickness - ECG voltage paradox is
present.
