It was likely that the hydrostatic effects of sustained centrifugal forces, the distortion of the heart's shape, as well as swings in the autonomic dominance pre- and post-Valsalva manoeuvre, contributed to the tachyarrhythmia." "The 12-lead ECG showed a narrow complex tachycardia with visible P-waves after the QRS complexes consistent with a long R-P' tachycardia. The intracardiac electrogram demonstrated a concentric...
