Wireless VHF Microphone

dear members.

I hope that all who read this are doing well.

I am doing quite well myself and my heart failure issues seem completely stabilized.

(CRT-D and Bisoprolol/Epleronone)

Im writing this post today, because I had some strange episodes I think might be related to my new Seinheiser VHF Wireless microphone. I am a part time singer.

I THINK I had palpitations during  different gigs

(Not sure what is was, I had while being on stage, and  I had to go on, cause I was in the middle of a concert, and like they say, the show must go on !)

I could not stop singing in the middle of a concert, and since I have a monitoring service at home; If something is wrong, they will see it from a distance and tell me about it.

Later I thought it could be the Microphone I recently purchased that might have caused these weird sensations, located in what I suppose is my right ventricule.

Does anybody have any data about VHF microphones ?

And if so, is there any specific thing I should be aware of ?

Anything I could do to prevent this from happening again ?

(other than holding the mic in my right hand, or just leaving the Mic on the stand as much as possible from now on, but that is not what I prefer of course. No need for a wireless mic if you leave it on the mic stand lol)

Thanks for your insight

Palpatations

Do you happen to have rate response enabled?  My guess is that it's the sound, particularly the drum, but it could be just the ambient noise, telling your pacemaker that you're working out.  This isn't unusual during a concert.  You brought your own concert.

 

Agree - loud vibratory music does it for me

Dear Tulp, it is lovely to hear from you and to know that you are stable and doing so well with your heart failure, that you are able to sing.   

You say you THINK you had rhythm disturbances (palpitations) during your performance.  Whatever symptoms you had did not stop you from singing, so your disturbances were clearly “tolerable” at the time.  

Much along the lines of AgentX86 comments, I feel this is caused by the noise (“vibrations”) from the music itself, heightened by the Microphone you purchased and this is likely to happen again and again if you create the same strong sounds.  If you try singing quietly, with low levels of background noise, I wonder if you would still get palpitations?  

I first discovered that vibratory, thudding sounds of our Nottinghill Carnival Festival that I foolishly agreed to attend a few years ago could set off wild palpitations, causing unstable symptoms, so I can believe that you noticed palpitations during your performance using an effective microphone!  I do not believe I had the setting Rate Response ON at the time, but I could be mistaken.  Anyway, the next day I got a call from my clinic asking about the long arrhythmia episode/exceedingly high heart rates that were seen on my downloads.  They advised me to call an ambulance next time I got symptoms like that.  I don’t think the ambulance would have got through the crowds lining the streets, so there is no way I will attend another music event with loud vibratory music.

In your case however, since you have a defibrillator, I would have thought if anything serious had been detected, you would have received a shock, so I will be interested to hear what your pacemaker records confirm?  Maybe instead of a shock, you received some initial anti tachycardia pacing therapies due to the noise levels and these caused your symptoms?  

Perhaps you need to find a better position for your wireless mic and if this means leaving on the stand, then why not try this to see if it helps?  As to the safety of your new microphone and potential pacemaker interference, if nothing helps, could you change the microphone for a smaller headworn one, to keep it further away from your pacemaker?  Worth a try too

Events

I've noticed recently that some large outdoor events like Glastonbury where sound levels are high, the drummer in particular often has a transparent screen in front of them.

I've always assumed that is some sort of protection for other performers on the same stage.

Certainly, very low frequency sound will cause some upset if powerful enough. Infrasonic?

Wasn't sound waves implicated in an embassy attack?

I wouldn't worry about the wireless microphone if used sensibly.

Stage electrics aren't known for integrity and more than one guitar player has jumped around when 240-volts zaps his instrument.

dont think so

Hello Agent, Gemita, and Piglet22

Thanks for your feedback.

I understand what you are saying, but the loud Music does not seem to bother me.

I have rehearsals every week, and we play loud in the studio.

One of the concerts was outside, very relaxed and it was with my acoustic trio (no drums)

I cannot use a microphone you are referring to Gemita, as sometimes I will move away from the mic so that it will not bother the audience.

Sound level can be variable depending on what you sing.

So that is not an option.

Perhaps I will try and contact Biotronik and ask them directly if they can tell me more.

I sure hope it won't shock me while on stage My doctor told me it would be better not to stand when you get shocked lol.

No it was weird like something was knocking from the inside nearly next to my stomach.

Don't know what it was, but the only variable, is the Microphone.

(Don't use the same one while rehearsing)

Take care

Tulp
