Magnetic Induction Cooking And Pacemakers?

[MEXICOWANDERER]

There is simply no guidance I have found about this. I have to avoid heavily charging alternators, generators, welders, etc. But how about magnetic induction cooktops? A thousand watts of power converted to producing a magnetic field is nothing to sneeze at. It does not harm the pacemaker but it can utterly disrupt the magnetically induced programming.

I don't need to experience Bradycardia or hyper rapid heartbeat. My cardiologist must be in quarantine. Telephone mailbox is stuffed and Boston Scientific puts me on endless hold.

One of the campgrounds I frequent has a Panasonic INVERTER Microwavew.
Panasonic tends to be "Slightly ahead of their time" or at least that's how they advertised back around 1970 when I was sitting in the snack area of a K-mart watching the Moon landing on a 5" black and white Panasonic PORTABLE television (My First Pop Up 🙂 )

There are days I identify with Dr. Jordan Kare (Rocket Scientist (Genuint) Author/Composer of song/poem Fire In The Sky from which Buzz Aldren read a stanza/verse after the last Shuttle disaster.. 2 days after I'd downloaded the MP3 from Promethus Music thank computers cause the server crashed right after Buzz read the verse)

Hi John,

It is good to know there is an inverter microwave. Is the temperature continuously variable? i.e. can you "dial in" the watts?

I believe you meant induction stovetop not microwave.

There are 15 settings for heat. You can set the heat by Watts or Temperature. The Watts range from 100-1500; temperature ranges from 140-400F.

My favorite feature. Sometimes you need to lift the pan to shake or flip the food. If you lift the pan off of this stovetop, it pauses and does NOT SHUT OFF right away! It will beep for about a minute. You may resume cooking instead of having to repeatedly redo your temp settings. Did I say I like this feature?

Hi John,

Yes, I meant "induction hob" and I've changed my original post. Thanks for catching that.

[MEXICOWANDERER]

Yes there are inverter microwave ovens. Look at PANASONIC

YES they limit intensity, not spend more time in the off cycle.

AFAIC the pacemaker manufacturer sets the standards. The only person that can modify those standards is the cardio surgeon who installed it. I am fortunate in that I don't have total heart block. Not an area in which to tinker.

My husband has a Medtronic ICD. Medtronic publishes an Electromagnetic compatibility guide and I often refer to it when I have questions about his device and risk factors.

That guide says to maintain a 2-foot distance between your device and the induction cooktop. Kinda hard to use if you have to stand away from it.

Here is a link to the guide.

We chose not to jump on the bandwagon with the induction cookers. They sound really neat but not worth the risk to DH.

Hi John,

I don't have that issue at all. But I am careful about the power settings on my NuWave. I do use a lid, too.

If I'm doing a grilled cheese, I, often as not, use the microwave to melt the cheese, and then brown the bread on the NuWave.

I’ll take it one step further, I do my grilled cheese open face to start, put one slice in a minute ahead of the second one and with the cheese on top of it. When the first slice is just about ready flip it over, cheese side down. When the second slice is ready build the sandwich. If you like the almost burnt cheese on top of a pizza you’ll love them this way.

A word of caution though, you MUST use real solid cheese, I prefer 5+ year old cheddar, if you cheese-like edible petroleum products you will have a messy cheese gravy sandwich.

Cast iron works, de Buyer fry pans work well, and coated cast iron from Lodge is an option. My home kitchen is full of all-clad, it will make you a better cook but is expensive.

One more thing don't use eggs in pot salad. wink

[MEXICOWANDERER]

Danged tough to beat a George Foreman grill for grilled cheese sandwiches. Upper and lower elements. And fast. 3-4 minutes.

Lid-on boiling of potatoes for pptato salad. Microwave mini new potatoes for 2 min. Switch spuds and eggs to water. Guisados (stews) I guess the butane really contributes to the misery with water vapor.

I have public power then the KATO generator which has better waveform than the federal electricity commission.

I am delighted that I can use a inductive cooktop safely.

You are a great group! Any more tips and hints? The inverter throttling needs to be investigated. My big microwave is an inverter and it does not attempt to cook while defrosting.

I use my microwave to sterilize currency. 10 seconds on high. On a Dixie plate

I have an induction unit (I think it's a Boss or Big Boss) not a NuWave.. Works great.. Near as I can tell it's as good as the NuWave..

It is a plug in unit (Portable) so I will set it on the counter plug it in. lay a paper towel on top of it to catch any splatter and my fry pan on it (Making sure I use one of the Induction compatable ones. not all are) or my other cookpot.. When I lift the pan after finishing the top is already cool and the paper towel wipes down whatever needs wiping.

Not a lot of waste heat either

With the resistive Burner or the gas burner there is waste heat goes up outside the pan (even if the pan is bigger than the burner) with the induction unit the pan IS the burner so the heat is contained where I want it.

Kitchen stays cooler
Uses less KWH
Easier to clean

I like it.. Big time.

Mex; do yourself a favor and try to find an try to find an inverter type of induction stovetop.

I tried a NuWave, only to learn I could not make a simple grilled cheese sandwich. What I got was charcoal darkness burned bread without melting the cheese.

The problem was that NuWave, and many others, operate in an on/off manner that is best described as BLAST-FURNACE/OFF. This is impossible to run on a smaller inverter genny without the annoying alternate racing and then idling engine noise.

An inverter type stovetop would not have the blast-furnace level bursts of power that might be dangerous to your pacemaker.

I have one that I can run on a 1000W Magnum inverter because I can set the power level to 900W, verified by Kill-A-Watt.

It is a Rosewill model RHAI 19002, 120V 60Hz 1500W.

Mex,

The inverse square law is clearly alive and well. Great to know that 12 inches is far enough away.

May I suggest the NuWave unit? It is more expensive, but blows most other units right out of the water imo. For example being able to select the wattage to 600, 900, or 1300. I've been using one for six years, though mine is too old to be able to choose the wattage. My watt meters can't "keep up" with the draw from the hob. It cycles on and off fairly rapidly.

Fairy Tale? I am an PhD candidate in the "field" of electromagnetics. Fifty years ago I was pursuing a doctoral thesis on a laser hologragrafic projection of a. Electromagnetic field.

But counts as zero when trying to interface magnetic encoding into a medical device. Or to transduce electrical energy into a field projection without spending hundreds of hours mapping with a gaussmeter.

Magnetic encoding of pacemakers means placing a Transducer on the chest that is connected to a transceiver the size of a briefcase. Analysis is complicated. I'll keep it basic: pacemakers affect the minimum number of beats per minute and a 2 wire synchronizes atrial and ventricular beats. This is not within the realm of fairy tales nor guesswork, assumptions, or ignorance.

35 years ago I spent thousands of hours using a military grade pulse generator of 40 kilowatts potential. Under the wrong conditions it would and it did heat low MU metal to incendescense. That's >900F

I am interested in minimizing antagonistic heating in an environment of almost 100F with an R/H of > 60% The tiered kWh cost of operating an AC down here is absurdly high.

Yesterday I decided to search Boston Scientific for an email address and finally found one. This morning I almost fell out of bed seeing a response. An answer.

Here I will paraphrase their answers. Keep in mind this is directed at a 2017 model AV pacemaker from Boston Scientific.

Do not permit the device to come closer than 12 inches to the emitter
Do not lean over the emitter.
Touching the emitter or cooking vessel has no significance.

Today I am busy. Tomorrow I order a single element cooktop.
I will need to buy a magnetic sensitive sauce pan and griddle

And lose the micro fiber sweat band.

Induction not a great idea? Until 3/5/2019 I would have agreed with you. The new house we purchased came with a 5 burner GE induction range. I want to remove and install a 5 burner NG range. My wife said NO. So, we purchased the required Induction Pots and Pans. After using the Induction for the past 15 months, this is the greatest thing in the Kitchen ever designed. It boils water faster than gas. The heat control is fantastic. Now I understand why all my RV customers like the Induction that came with their RV. Doug

Doug,
Mex has a pacemaker and is concerned about electromagnetic interference/interaction. Not concerned about the quality as a heating device.

I understand that. But the way he posted it made it sound like Induction was a fairy tale. THAT is what I was responding too, not the problem with medical devices. Doug
