some people have limited knowledge about chloroquine . it is an effective drug to reduce viral load and inflammation in COVID cases but unfortunately some people may develop serious side effects including cardiac arrhythmias .It is a drug widely used to treat SLE( an autoimmune disease).Not everyone get side effects - if you look around the world many countries are using chloroquine with caution and monitoring.
So for that monitoring yes GMV patch is helpful.

one of the issue chloroquine causes is QTc prolongation in ECG - in simple words a cardiac conduction issue which may lead to cardiacs arrest or complications.

there are many many drugs in market which cause QTc prolongation in ECG and in my view gmed patch is useful in those cases too in future.

kindly refer to MIMS to see how many drugs or medicines cause QTc prolongation

my qualification- a graduate medical professional

all in my opinion- you do your own research
