Funtabulously Frivolous Friday Five 244

Just when you thought your brain could unwind on a Friday, you realise that it would rather be challenged with some good old fashioned medical trivia FFFF, introducing the Funtabulously Frivolous Friday Five 244

Question 1

What is the Mandela effect?

Reveal the funtabulous answer

A false memory, shaped by social reinforcement or false news and misleading photographs.

The name of the theory comes from self-described ‘paranormal consultant’ Fiona Broome in reference to her belief and of many people, feeling certain they could remember Nelson Mandela dying while he was still in prison back in the ’80s. Her explanation was about alternative realities but most commentators believe in the social reinforcement theory. [Reference]

One of the most famous examples that comes to mind is the Darth Vader line “Luke, I am your father.” He actually says, “No, I am your father.” [For more examples click here]


Question 2

What is the ‘Bix rule’?

Reveal the funtabulous answer

The rule states: with SVT, in which visible P waves are situated midway between ventricular complexes, there is a probability that there is a P wave lurking within the QRS.

Therefore, it can be an atrial tachycardia or atrial flutter with a 2:1 AV conduction.

The rule is named in honour of Viennese cardiologist, Dr Harold Bix who worked in Baltimore.

Question 3

If you were climbing Everest why might you see Osborn wave at you?

Reveal the funtabulous answer

Because you are hypothermic. 

The Osborn wave or J wave is a positive deflection at the J point (negative in aVR and V1).

Typically seen in temps under 30 degrees Celcius but they can be a normal variant, due to medications, hypercalcaemia, neurological insults and idiopathic VF.

Eponymously named after John Jay Osborn (1917-2014) following his 1953 ‘current of injury‘ description in hypothermic dogs.
