Hey,
Does anyone know if premature arterial contractions will affect the results of a polygraph???  Need to know!

I'm not sure how he knows that as what little research we have on them shows they do nothing as far as a decision of truth or deception goes.  Not surprising, given they are usually pretty benign and few require treatment of any kind. They don't typically result in an increase in BP, which is what we look for on a polygraph test.  It's a better question for your physician if you think it's a problem.

You'll find your physician might need an explanation of polygraph to make a determination, but if you want or need the test, doctors will often help make the decision (with the examiner) as to the appropriateness of polygraph.  Many of us have refused a person a doctor later cleared.  Examiners are trained to err on the side of caution when it comes to heart conditions of any sort.  There are a few that are so common (such as this and Mitral-valve prolapse) that they don't scare us as easily.

First, that's wrong - yet another indication that you don't read the literature.  Secondly, even if it were true, why would that be bad?  That is what most here do.  Do you want me to hold you up so you can take a breath?

I have mitral valve prolapse with regurgitation and also a heart murmur. Can either of these conditions, seperately or together, produce a false positive during an examination?

My friend Misty Croslin was recently told by prison doctor that she has heart mumor. She already knew because she was born with it. Failing poloy has caused her major problems.

Jeff,

While it's possible that your history of heart problems had some influence on the outcome of your polygraph "test," you need to bear in mind that polygraphy has no scientific basis to begin with. Ultimately, there is little to be gained from trying to divine why an invalid procedure yielded an erroneous result. See our book, The Lie Behind the Lie Detector for a thorough debunking of polygraphy:

You'll also see how polygraphy is inherently biased against truth-tellers.

I am no liar,

There is no research on the effects of pacemakers or blood pressure medication on polygraph results. But it doesn't matter. Polygraph "testing" has no scientific basis to begin with. It's a fraudulent procedure that was concocted by interrogators, not scientists.

My best advice to you is to cancel your lie detector test and not subject yourself to this degrading pseudoscientific ritual.

John Castellano, I have faced this problem many times, especially when I ran PCSOT exams.

An ethical examiner (please, skip the jokes) will attempt to run enough charts to obtain a sufficient number of scoreable spots, that is to say, spots that are free of distortions.

If that threshold is not met, the official outcome of the test is "no opinion." The examiner's report should list any known (or claimed) conditions that could influence the collection of data, or have any meaningful bearing on the examinee's overall suitability as a polygraph test-taker.

If you are obligated to take a polygraph, say, as part of supervision or treatment, it is highly unlikely that you will be given a free pass.
