I agree with the others, don't treat bigeminy. ...It's some kind of EMS lore that never seems to die that bigeminy is a terribly malignant rhythm and has to be squashed no matter what the consequences.
The meaning of the autumn equinox is intertwined with that of the four points of the year (the two solstices, and the spring equinox), which each mark stages in the esoteric work that begin anew each year, and form a symbolic cross in the wheel of the year, with the sun (Son/Christ) at the center.
The autumn equinox marks the arrival of the season of fall, traditionally seen as a period of changes leading to the dark of winter. In Holidays and Holy Nights, Christopher Hill points out that for Christians who observe the liturgical year, autumn is actually the beginning of the cycle.
