Yesterday we had a lecture on EKG interpretation and the cardiologist giving the lecture was chatting about using the R-R interval to calculate heart rate. It went like this:
"Take 300 and divide it by the number of small squares between the R to R interval...that gives you the HR....so....if there are 2 squares between the R-R what is the HR...?"
-Everyone stares back in silence.
"150!!" he says exasperatedly.
"So look at this one...there are 3 squares between the R-R interval....what does that make the HR?"
"JEAZUS! Are ye RETARDED? It's NOT that complicated!!"
I almost lost my sip of tea out the nose.
One of the many hilarious quirks of Ireland and Irish medical training. The consultants actually yell "JEAZUS", and call you "retarded" during lecture, and no one even blinks an eye.
