Double Bass Fainting during rehersal

Hello all,

I made this account today to tell of an experience I had yesterday. For context, I am a student who has been studying primarily classical double bass for the past six years. the first four years I played almost all standing up and when I graduated High school I began sitting as I moved on to more difficult solo repertoire. Invalid Link Removed is the stool I use for most of my performances with my schools orchestra and solo recitals.

I was scheduled to play in a show yesterday the 29th at 7pm and there was a rehearsal that afternoon at 3pm. at around 5/530 I fell out of consciousness and woke up on the floor with some concerned friends around me. I experienced some unsettling tunnel vision just before and right as I thought "I need to set down my bass and go to the back" I found my self coming out of syncope. I had eaten plenty and it had not been very long since I drank water (though dehydration was most likely a factor).

I did not play in the show and was fortunate enough to have my father pick up me and my instrument and take me to the ER to make sure I was okay. Everything checked out fine on the EKG and after an extended conversation with the doctor it became increasingly apparent that the cause of this was in fact my stool, how I was sitting on it, and how long I remained seated.

I sit on the forward edge of my stool, with only a small part of my butt on the lip of the seat with my back upright. Essentially the bottom part of my ass and top part of my thigh are pressed against the top edge of the seat. The seat is rather thin and has no real padding, it is really just a wooden seat. What we determined was that the pressure on the back of my thighs actually blocked the major veins that carry blood into the upper body. This combined with the fact that my legs were immobile made it so not enough blood came to my upper body and brain, leading me to pass out on the floor.

Despite how scary the whole experience was I feel so happy and grateful for a few different reasons. Most importantly, I am okay. The other bassists who saw me fall said I did so rather slowly and when I came to I had no pain from the impact of the fall, I could have quite easily hit my head and done permanent damage. Additionally in an incredible sequence of events my bass was not hurt in the slightest. The bassist playing principle to my left managed to toss his bow from his right hand to his left while instantaneously grabbing the neck of my falling instrument in his right hand. Chances are if he was unable to do this my instrument would be damaged severely and it could have easily harmed his own bass as well (an incredible $50,000 Italian bass). I am also just so relieved that this wasn't the result of something much more serious like a heart condition or the like.

So for me, the big moral of this story is to listen to what your body is telling you. My legs and butt region where the seat hits was feeling quite uncomfortable about 45 minutes before but for whatever reason I did not stand and stretch. At the very beginning of the onset of lightheartedness I told myself to take some deep breaths, when I should have immediately set down my instrument and told someone what was happening. I now have a high quality cushion made of dozens of latex air bladders that fits quite well on the seat and cushions the hard edge. Even with the extra padding I must be very careful to stand and stretch my legs if I plan on sitting for an extended period. I can easily see this scenario the other way around, making sure to sit periodically if I plan on playing standing for an extended period.

I hope this is the right section of the forums to post this in, I figured it had enough to do with seated technique to make it relevant. I am also interested in seeing if any other bassists have had a similar experience. I hope this can serve as a sort of PSA about listening to your body when performing or practicing.

I'm happy to answer any questions about the whole fiasco if I was unclear, my mind has been reeling through the events non-stop since.
 
Glad you're OK. I've never experienced this to this degree, but as a seated jazz player I normally sit on a padded stool with my feet up on the same rung height on different sides of the stool. Several years ago, after a recent knee surgery, I was unable to bend my legs enough to sit in my normal way, so I had to sit in a more traditional stance. I found myself having blood flow issues like you describe and being a bit lightheaded at the end of the later sets of gigs during this time. Fortunately the knees are healed enough now to go back to a healthier posture. Good luck finding your new playing paradigm!
 
Well the good thing is that you didn't get hurt, and the bass also made it through.

I rarely sit, only when my "bad" knee is giving me fits. Whether you are sitting or standing, it is important to take a break and move around once in a while. A couple of weeks ago I had two gigs in one day - a first for me on upright bass. Played for almost three hours at an outdoor afternoon event, then packed up and headed into the city for a midnight gig.

I woke the next morning feeling like I got hit by a truck. Hips, knees, and back were hating me. I never had a problem playing for three hours, but tack the fourth, fifth on plus hauling gear, not hydrating well, and eating junk food on the run - and you get some poor results the next day. You have to respect the amount of physical energy it takes just to stand/sit there with the beast, let alone play it for hours. My hands and arms didn't hurt a bit.
 
i would take that diagnosis with a grain of salt. ive been playing sitting for over 25 years, never a problem no matter what kind of cushion or lack thereof. its very hard to diagnose ventricular tachycardia after the event is over. will leave no trace on ekg. its the number one killer of people. more than all cancers combined. could be that or any of 100 other things (some serious some not so serious). you did the right thing by going to the hospital, but working in the medical field i can say that it sounds like a cop out diagnosis to me, and if you dont think that kind of thing happens you're dead wrong. i see it all day long... stay alert for any future symptoms, keep a journal of when they occur and what you were doing beforehand, take your pulse if you can before you black out, and see someone right away if you get this again. i hope you never get this again
 
I don't think it is a "cop out" simply because the doctor at the ER basically gave me a short list of things that could lead to syncope as I described it. I know I wasn't as hydrated as I should have been and I definitely haven't had as much sleep as I should as I am finishing the summer session at my college. There seems to be a lot of factors that could have led to this and I fit the bill for many. The way I see it as of now is that it was likely a combination of all these things; however, I have yet to follow up with my primary care physician so I'm sure I'll have more to share at a later date. This is best case scenario, where it is something that I can control by being aware of what caused it. Of course there is a chance it is something more severe.

Re-reading what I originally posted I come off as very certain, but this is just the inference I have as of right now. I'll tell you guys more when I know more.

I would like to emphasize how truly uncomfortable I was were I was connected to the seat, and I should have stretched or taken a break or something. Also, strange as it may seem, the underwear that I had on in rehearsal was less than comfortable, rather tight on my waist. I could see this being yet another factor.

so then did your guy mention vasovagal syncope?
 
I think the fainting had to do more with your breathing than with the sitting. Probably some tension or stress (maybe because of your uncomfortable sitting position) had you breath very high and that caused the fainting. Like hyper ventilating. I am no doctor but that is my guess. Good luck and thanks for sharing this!
 
I use the same chair for about 5 years now and have definitely gotten to 'know' it - and my body
over that time. You don't mention whether you sit with your feet on the floor and that could be a pressure
factor on the upper thighs. I usually keep my feet on the floor with this chair except for brief change of position
breaks. I, too, have been in the medical profession and you sound a bit young statistically for ventricular tachycardia.
I would favor fatigue, dehydration, and stress as the causative factors here for vaso-vagal syncope in addition to pelvic pressure. Standing up
for a stretch really helps! All in all, I think it's a pretty good chair for the money. I would be interested to know what you are using
for a cushion, though. The seat is a little firm.
 
I'm not the one to contradict what a doctor says, but experience tells me it could simply be stress; I find I sometimes almost stop breathing if I'm very tense, to the point of getting a bit light headed before I realize what I'm doing. When I took my drivers license test for motorcycles the instructor told me a person had just fainted from nervousness, he simply forgot to breathe and fell over, and it was not the first time that happened. Moving around a bit and remembering to breathe (I know, it sounds silly) helps.

Anyway, I hope you find a good explanation so you can avoid a repeat.

statistically yes, but teenagers can get VT for sure. also, vasovagal syncope is not something to be taken lightly, especially if it occurs again. im surprised he's not getting a tilt table to confirm

I do indeed keep my feet on the floor, I feel as if that takes some of the pressure off of my back. You are right though, by keeping my feet planted I place a lot of pressure on my upper thighs.

I really like the chair, and I love how portable it is. Most other chairs would mean an extra trip to the car. My dad is paralyzed from about the chest down and uses cushions on his chair as well as his car, and I'm using one of his old cushions he used to use in his car. Can't find a picture of it exactly but its a lot like this but in a more rectangular shape, it fits nicely on the seat. In the long term its great as it will not pack down over time, only lose air which can be pumped back in.
