Rectal manipulation results in a vagal stimulus and will slow your heart. In fact, in someone with cardiac conduction problems (';heart block';) a rectal examination is contraindicated.
Rectal exams and rectal thermometers are not necessarily associated with valsalva.If ill be using a rectal thermometer will it increase or decrease my heart rate? pls explain?
Stick the silly thing under your armpit.. There is no need to take a rectal temperature. Stick the thing in your mouth.In ten years of working in a CCU I have never taken a rectal temp. Yes it can stimulate your vagus nerve and slow your heart rate so why do it that way?If ill be using a rectal thermometer will it increase or decrease my heart rate? pls explain?
decrease because it starts something called the vasalva manuever. it slows your heart rate. it causes death in some extreme cases.
Either. The anxiety will increase your heart rate. I'm not sure a thermometer is enough to cause vagal stimulation, but if it did, your heart rate would slow down.
You do realize of course that a thermometer measures body temperature and has nothing to do with heart rate... don't you?
