Fitness-7/6-press, "Unilateral Madness", gymnastics work

Monday WOD-"Unilateral Madness"

I started today of with some press work. I was going for 3x3 with max effort on the last set. My sets looked as follows:

-135 x 3
-145 x 3
-155 x 3

I wanted to go for a fourth set at either 160 or 165 because 155 wasn't too bad but decided to stick to the game plan and called it good. Next we went after a longer met-con that ended up kicking my butt. It was two rounds for time of:

-12 right arm kb pushpress, 24kg
-12 left arm suitcase deadlifts, 95#
-run 800m
-12 left arm kb pushpress, 24kg
-12 right arm suitcase deadlifts, 95#
-run 800m

time=25ish

I was absolutely destroying this workout. My runs felt effortless and the lifting portion seemed pretty light. As I got back in from the first run on round 2, I was only about 15 minutes into the workout. Then my heart rate went crazy (I get tachycardic every once in a while) and I couldn't continue. I muscled through the lifts and then took off on the run and had to stop and lay down until my heart rate went normal. It took forever. Once I calmed down, I got up and finished the last 800m. I've been told my tachycardia issues may be related to electrolyte balance and I think I agree. My diet's been crap lately and I've gone tachycardic a few times in the past month that I've been slacking. I was on pace to crush this one but poor nutrition seems to have cost me. More reason to shape-up.

After I finished I decided to do a little un-timed gymnastics/bw work. I did the following:

-100 situps
-20 ring dips
-15 hspu (1/2 range of motion)
-5 rope climbs, 12ft rope
