Heart behavior seemed normal except that the heart rate display vanished 4 times during the rowing session
Virtuously early this morning, I rose from bed.
Argument might be made by some that rising early has nothing to do with virtue.
Nonetheless, it somehow feels virtuous.
I will accept virtuous feelings where they can be found.
Surprisingly, that virtue was sort of swallowed by about three hours of doing nothing in particular before finally taking the reins and spurring myself to change into workout clothes and start that sort of work.
Happily, once the workout strokes were started, they flowed unabated until the sessions were adorned with sweat and completed.
In keeping with recent practice the first workout session was 200 Calories on the SkiErg.
Next after the SkiErg a bit of rebellious protest made itself heard from the subconscious realm. It expressed desire to do only 3K rowing today, like yesterday’s had been, instead of the more usual 10K.
Getting right down to business bargaining with my subconscious, we arrived at a prompt agreement to compromise with 5K rowing instead of the full 10K or a more paltry 3K.
So the workout sessions were quickly done and without irregularity on the part of the heart except for what is alluded to in today’s title: four brief vanishings of heart rate from the display.
Not that I’ve ever done any yoga. I haven’t. But my better half has sort of suggested it a few times.
One and only one workout session was the original intention this morning. That workout was to be 200 Calories on the SkiErg. It was done.
Yenning for just a little bit more workout, I set up the rowing machine for 3,000 meters after finishing with the SkiErg.
One session of 3K on the rowing erg seemed enough to have earned some coffee and breakfast.
Generally I like to do a minimum of 10K rowing in addition to whatever is done on the SkiErg, but today seemed like a day to take a vacation from the usual workout.
A grand total of 379 Calories was burned and a few ounces of sweat were generated. The coffee tasted good afterwards.
The first workout session today was 200 Calories on the SkiErg.

Perhaps, but not definitively. Yesterday the question arose as to whether the cause for heart strangeness (atrial fibrillation rearing its head) during the last two of yesterday’s five 2K pieces was having eaten a large breakfast and then resumed rowing while the stomach was feeling full.
Early this morning, before having so much as a crumb of food or a sip of coffee, I began the day’s workouts.
Remembering yesterday’s words, “Perhaps I will try duplicating today’s workout again tomorrow…” but on an empty stomach from start to finish, that thought was put into action and fulfilled this morning.
Happily, there was no heart strangeness from start to finish.
Actually, I did feel a tiny bit of cardio flitter-flutter in the chest. It happened one time and was during the third 2K. But it was so ephemeral that it bordered on being imaginary, though vividly so. Heart rate did not vanish from the display like it does when Afib is more persistent, so I will attribute it to being an imagination of the heart.
Perhaps rowing on a full stomach isn’t a good idea. But on the other hand, perhaps it is merely a coincidence.
Scientific experiment, this was not. Scientific experiments are more thorough. Experiment, it was. And I will keep it in mind for future reference.
Following are screenshots and data for today’s workouts.

Today’s heart behavior was virtually perfect, until after my stomach went from Empty to Full, with breakfast.
Perhaps I will try duplicating today’s workout again tomorrow. But if I do, there will be one difference. That difference will be to postpone eating until after all parts of the workout are finished.
Usually, eating before a workout seems to make no difference.
Zero heart strangeness happened during the first session, which was 200 Calories at RPE Level 2 on the SkiErg.
Zero heart strangeness, likewise, during the first of five lively though moderate 2K rowing pieces which followed the SkiErg session. Well, I should say almost zero during that session.
Lively though moderate rowing continued in the second and third of five 2K rowing pieces and heart behavior was perfect during each of those. My stomach had been completely EMPTY during each of those sessions.
In between the third and fourth of five 2Ks, I ate breakfast. Stomach went from Empty to Full. It was a big breakfast, volume-wise, because it included a couple quarts of water in the form of protein drink, Chia drink and 12 ounces of coffee. Plus, there were 3 pita sandwich things.
Needless to say, but I’ll say it anyway in case it is not obvious, I felt very “full” in the stomach area after breakfast. But I didn’t want to wait for the sandwiches and liquids to percolate through the digestive tract, so I didn’t wait to go the rowing machine.
Going at a moderate pace of about 2:17/500 meters, heart rhythm disruption made itself felt after about 1,500 meters of the 4th 2K. It wasn’t drastically irregular, but I could feel it now and then and the heart rate display went blank a few times during both the 4th and 5th of the five 2K rowing sessions. If you look at the screenshots (below) of the finish screen views for the 4th and 5th 2K sessions, you can see that in each of them the heart rate display (bottom right corner of the RowPro screen) is blank. That’s because heart rhythm was too erratic at the finish, for the heart strap to transmit a heart rate signal.
It is PUZZLING and I’m wondering if rowing on a rather full stomach was a significant factor to have caused the fibrillation.
Everything became normal again, after all the rowing was done.

Most definitions of defibrillation only refer to applying an electric shock to the heart. But it seems there are other ways, less shocking, to coax heart rhythm back to normal. Today’s workout sessions on the ergs seemed to work as an effective defibrillator.
Defibrillation has a few definitions but what they all have in common is that they relate to restoring normal heart behavior by stopping the fibrillation of the heart. If you’ve ever seen a fish flopping around out of water, that’s a good analogy for heart fibrillation.
Every time my heart goes into its floppy-fish mode it is annoying. It’s worse than annoying if it happens after bedtime at night. That’s what happened yesterday evening. It continued all night and caused sleep loss. It was still happening this morning after I gave up trying to get any more sleep and got up for the day.
For the sake of possibly benefiting the heart and its mitochondria, I decided to start today’s workouts early in the morning, before having any breakfast or coffee.
I decided to divide the day’s workouts into smaller than usual increments, to arrive at the same desired goal of time on SkiErg and rowing machine.
Because the SkiErg session of 200 Calories is the shortest of my usual workouts, I did that one first. One nice thing about the SkiErg is that I don’t have to bother with shoes or socks. It can be done barefoot as easily as with shoes on. Somehow, using the SkiErg barefoot seems to make the experience seem more like play than work.
Doing the SkiErg session felt like swimming in molasses. I was very low-energy, though heart rate was high.
The first workout was 200 Calories on the SkiErg. Heart rate was too high and felt irregular throughout that session. I felt low-energy and went very slow, averaging about 2:48 for the session.
First of ten 1,000 meter rowing sessions. Heart rate was irregular and too high.
The next workout was on the rowing machine. The goal was 10,000 meters total, by doing ten sessions of 1,000 meters each. For the first 1,000 meter rowing session (see image above) I didn’t pay any attention to pace and just focused on continuing to row. Heart rhythm was very irregular and disappeared from the RowPro quite a bit of the time. Heart rate was abnormally high – much too high for duration and effort level. It was done at an average pace of 2:12.5/500 meters.
Second of ten 1,000 meter rowing sessions. Heart rhythm was still irregular and a bit too high.
After the first 1,000 meter session I took a break and got the Mr. Coffee busy making a pot of coffee. While coffee was brewing, I rowed the 2nd 1,000 meter session (see image above). Heart rhythm continued to be very irregular, but heart rate was in the normal range for the duration and effort level. I only focused on continuing to row and it was done more slowly than the first at an average pace of 2:17.7/500 meters.
Third of ten 1,000 meter rowing sessions. Heart rate was irregular at beginning but smoothed out during the first 100 meters or so.
When I sat to row the third 1,000 meters (see image above) I decided to not only focus on simply rowing the distance, but also to do the session at a pace equal to or faster than the first 1K. It was done at an average pace of 2:12.5, like the first 1K of the day. Heart rhythm was irregular at the beginning, but smoothed out during the first 100 meters and had normal rhythm for the rest of the piece. Heart rate was a little bit too high but almost normal for the duration and effort level.
For the 4th through 10th 1,000 meter sessions, each was fractionally faster than the previous, except for the 10th. Heart rhythm and rate was normal during all of those rowing sessions from the 4th through the 10th of 10.
The 10th 1,000 meter session was done at a bit faster pace of 2:07.9, to see if it would trigger irregular heart activity but it didn’t seem to trigger anything out of the ordinary. It also had normal rhythm and rate.
Therefore I conclude that the workout sessions on the ergs were somehow helpful in defibrillation of the irregularities of heart rhythm.

Finish screen for today’s 10K rowing session. The circled area of the heart rate plot shows where heart rate shifted too high though effort remained the same or slower.
At the start of today’s sessions everything seemed normal. I decided to row 10K first and then burn some calories on the SkiErg.
For the first half of the 10K rowing session everything continued to seem normal, though heart rate disappeared from the RowPro display a few times.
I decided to take an aspirin break after about 4,000 meters of rowing. The break lasted between two and three minutes. Sometimes a little aspirin seems to help heart rate become regular again.
But this time it didn’t help and after I returned from the rowing break it became more irregular. Also, heart rate shifted to become too high.
I didn’t let a little Afib (atrial fibrillation) put too much of a damper on things though, because I wanted to earn another exercise-induced “sleeping pill” for tonight’s sleep.
The 10K was finished. It was followed by two SkiErg sessions of about 100 Calories each. After the SkiErg sessions, a very slow 500 meter rowing session was done.
Heart rate remained irregular and too high through all of the remaining workout. But it’s okay now. The exercise-induced “sleeping pill” was earned and it’s effect can already be felt, early in the evening. No need for Sleepytime tea.

Report for the very slow 500 meter rowing session. Heart rate (circled) was about 40 BPM too high for the low effort level.
Effort was made to do workouts today but they were done slowly.
Main reason for pushing myself to do work on SkiErg and rowing machine: If I don’t exercise I won’t sleep well.
Because of the desire for the “sleeping pill” effect of aerobic exercise, I burned 200 Calories on the SkiErg at RPE Level 1.
Energy for SkiErg was low, but energy for rowing was lower. After the 200 Calorie SkiErg session my subconscious suggested I take a break before doing any rowing. The break stretched out and extended in the dimension of time….
Realizing that my subconscious was trying to con me out of doing any rowing at all, I dragged myself to the rowing machine and set it up for a 10,000 meter session.
Some incentive to keep rowing was provided by watching a screen recording of a slow 10,000 meters session done February 24, 2018. I allowed myself a 1,200 meter head start before that screen recording began and prodded myself to stay ahead of it. By the finish of my 10K, I was still ahead of the screen recording but my lead had diminished to about 200 meters.

The sleeping pill I labored for today was none of the above.
So as to get a good night’s sleep tonight I spent 65.58 minutes laboring on the ergs.
Labor doesn’t have to be extremely hard to act as a sleep aid, but it has to last a while. Thirty minutes or more seems to be the minimum for exercising aerobically to serve as an effective sleep aid.
Ergs have a magical effect on sleep if they are used for a sufficient time at a moderate aerobic pace.
Each of the two workouts today was done at RPE Level 2.
Perhaps you wonder why today’s blog post title mentions a $16.40 sleeping pill. Do you? The answer is this: if you were to assign a value of $15.00 per hour to the 65 minutes and 35 seconds work on the ergs today then the wages for that time would amount to $16.40.
You might favor different value for an hourly wage of physical labor, but the value of a good night’s sleep is priceless.

Dependably, every August Concept 2 features the “Dog Days of Summer” challenge. That challenge was one motivation for today’s low-energy workouts.
Other than a minimal number of specified meters each week of August, there are no other requirements for this easy challenge.
Going slowly was today’s workout approach. The workouts consisted of 200 Calories burned slowly on the SkiErg and 10,000 meters even more slowly on the rowing erg.
