comment What are the highest and lowest amplitude values in ECG for humans?
As you mentioned this is the case for healthy ECGs, old infarcted areas (e.g. post MI) regularly cause these values to be exceeded - often with very prominent Q waves which I think would go beyond your suggested minimum voltage.

comment Why is the administration of exogenous Anti-D not harmful to the foetus?
That's an excellent article, thank you. I had wondered if they used primarily IgG2 to reduce placental transmission but this is not the case (the article indicating IgG1 and IgG3). If a 125 unit dose can neutralise only 1.25 ml of D+ve blood and not all of it crosses the placenta then this is likely to be an insignificant dose to cause harm. I assume this could cause harm with a greater number of repeated doses after sensitising events but I think this is sufficient evidence to say that it is indeed a dose dependent phenomenon. Thanks!

comment Are there medical treatments that were so effective they were never subjected to a randomized control trial?
Often new treatments are compared against best available treatment rather than placebo to alleviate ethical issues.

comment Can systemic intravascular thrombosis cause brain infarction?
@WYSIWYG duly added a couple of examples of references, the phenomenon is very well known and understood so others viewing the question may find it easier to search for Atrial Fibrillation and Stroke

comment Does suffocation pain involve nociceptors?
I've heard it more commonly described as a sensation of panic rather than of pain, resulting from a rising [CO2] as detected by carotid chemoreceptors
