So I was giving a magic lesson and showed the kid and his dad the pulse stop principle. He said he was going to be a surgeon and years ago they had a little pen like device that could be used to "hear" a pulse using ultrasound. You'd Hook up a little speaker and put the pen to the wrist and you could hear the pulse beating. This way you could get the whole audience in on it, and the whole audience could hear it stop... better than one persons word, even though they are telling the truth. Anyone ever heard of this before, and what the device is called? where can you get one etc...

All you need are an amplifier and speaker with a microphone. You might try something like a guitar pickup mic and an elastic strap to hold it to the wrist. The guitar mic has a clip that can hold other things than a guitar -- like a stick-like probe to touch the artery, if necessary, and ice-pick to turn a door into a microphone. (Think of other things!). There are myriad possibilities with this. You might look around under "electronic stethoscopes." For example: http://www.facelake.net/index.html

There are also EKG machines that some have used.

The device you are referring to is a Doppler pulsometer; you can buy easily. A digital stethoscope won't work. It listens to heart sounds and normally the peripheral pulses are silent.
Lior manor I beleive uses an infra red oximeter with that pleasing anaesthetic 'ping' that hear on movies (& in real practice) to demonstrate a pulse stop.
I make the pulse stop visible with my version!

Not all brands have sound. Not all brands monitor the pulse. Anyone actually know of the models and brands that would work?

Some have suggested a stethoscope hooked up to a microphone.

Any suggestions how to get this effect hooking up a real ECG Monitor?

PM me if you wish.

Old thread but still...

I just found out the hard way that a stethoscope doesn't hear the pulse on the wrist. A stethoscope can hear the heartbeat but is useless for the radial (wrist) pulse and brachial (inside arm) pulse.

I have this in my seance show and have toyed with the idea of using a microphone on my wrist connect to an amplifier (or maybe hook-up a digital pulse meter). The problem is I think that the more technology you introduce to the routine, then the more the audience will look for where the gimmick is. A human hand on a human wrist can't lie...can it? A machine that beeps can just be a playback recording.

A friend suggested that I use a stethoscope so my volunteer has a clear beat. I bought a medical stethoscope and just presumed that it would work. Oh well.

Unless someone knows how to gimmick a stethoscope to render the earpieces silent or mute the diaphragm, then I just wasted some time and a little cash.

Turn this problem on its head. Most people would assume a stethoscope would work. If one were to covertly tap the stethoscope then a pulse would be heard, even on the carotid artery, and could be stopped at will.

EKG machine will not work as the pulse is created by pressure change in the veins, like little waves, and EKG detects electrical impulse. If a person uses the EKG the unit is rigged or they actually stopped their heart. A recorded pulse could be used and use a device that looks like a medical device to complete the illustration. Hope this helps some. I usually have to reverse the illusion. My cadavers have no pulse so I have to create one.

I still like a stethoscope. It's portable. It's easy to use. Everybody understands it. It has, basically, nothing that can go wrong.

Hmm, I have a Doppler with the appropriate probe for veins (larger probes are used for pregnancy purposes).

I never gave it a thought to use it in a pulse stop routine. May be an interesting idea - except for the gel used which is messy at the best of times.

This contains some interesting ideas that could be applied by those with a knowledge of the asana, bandha and pranayama.

Re stethoscopes.
You can't hear the pulse over vessels, just the heart: if it is double sided (bell & diaphragm) then you twist it to activate the correct side. This would be a simple way of rendering it silent after you have stopped your pulse (it is also why you will see me blowing into the bell or tapping the diaphragm iin my day job!)

Once I thought imy own model (some 20 years old now) was failing: when I took off the soft earbuds I was both amused and disgusted to find jammed full of earwax! Smile

Docsteve - it is a twistable bell and diaphragm model but even when the diaphragm is in the "off" position, you can still hear a faint heartbeat being carried through the metal body to be picked up by the "on" bell. I thought of that idea but dismissed it when I noticed the faint heartbeat. I will try to experiment a little and see if moving the "off" diaphragm an inch or two sideways eliminates the faint heartbeat.

Ok Aheads - try this: block your bell end with blu-tack.

By which I mean the stethoscope!

Also don't worry about a faint noise - a nervous spectator who hears a loud heartbeat will be doing well; if its just faint chances are it will be reported as absent.

If it IS heard faintly, then smile and say THAT is the power - to relax the heart so much it appears to have stopped peripherally, though OBVIOUSLY some pumping has to occur, if only to get blood to your pineal gland/third eye...

hope this helps

OK. I've tried blu-tak and tape but you can still hear it. I think I have found a work around though using a mixture of Brynmore14's idea, misdirection and gutsy bravado.
