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

Premature arterial contractions originate in the atrial chambers (PAC's) or in the ventricles (premature ventricular contractions - PVC's).

There are varying underlying causes of both PAC's & PVC's -  most of which will produce unreliable cardio tracings on the p/graph.

Arrythmias(or murmurs) usually occur during the diastolic phase of the cardiac cycle - resulting in irregular and  'dropped' diastole tracings. This often requires frequent re-centering of the cardio tracing.

If your PAC or PVC activity is frequent and regular, you should be deemed unsuitable for polygraph testing.

Unfortunately, you would probably have to be in a coma before an examiner deemed you to be unsuitable for testing.

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.

Noodle suffers from selective factual retention. What also transpires is that he has apparently never carried out any of his own research - published or not. His greatest talent demonstrated to date is the parrotting of "the literature and the reading" - which he has now also
claimed as his sole preserve.

Like I said, you would need to be comatose before BC deemed you to be unsuitable for polygraph testing.

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 recentl took a polygraph test and fail and i do have heart problems. My heart races from time to time and i do have high blood pressure prolems. The prblem with this whole thing is i was telling the truth and i still failed, I even failed my name. The thing is no machine no matter how much we rely on them can tell you about you. It cant look into the past or say whats on your mind. It supposedly can only tell you if you are being DECEPTIVE or not. Not if you are telling the truth or not.
And can one be deceptive about his/her name. Test of the polygraph have shown that a liar can pass the test and those you are telling the truth can fail. So my advice is to take this test at your own risk.

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?

Lena,

While there is scant research on the effects of any medical conditions on polygraph results, it seems unlikely that such conditions as you mention would directly cause a false positive. But you should be aware that polygraphy has no scientific basis to begin with and is inherently biased against the truthful. False positives are common. For more on the scientific status of polygraphy, see Chapter 1 of The Lie Behind the Lie Detector and the sources cited there:
