The use of cel1uLar (mobiLe) phone has been exploded worLd wide during Last decade. Their rapid adoption by generaL public has resulted in an increased research interest in possibLe harmfuL health elfects(Tahavanainen et aL, 2004) . This common use of ceLLuLar phones has given rise to concerns about the potentiaL influences of electromagnetic fields on human physioLogy (Croft et at, 2002),
We studied the effect of eLectromagnetic fieLds emitted by ceLLuLar phone onfetaL heart rate patterns, end diastolic voLume , end systoLic voLume . stroke voLume and cardiac output.
Our results showed that after use of mobile phones on different
gestationaL
ages
(group
I,
II
&
III),
significant
increase
in , FHR and
significant
reduction
of EDV.
ESV,
SV &
Cop,
The
percent of reduction
in
EDV
was
more than
the
percent
of reduction
in
ESV
in aLL
groups, This prominent decrease in EDV more than the decrease in ESV suggests that the decrease in SV is mainLy due to decrease in contractility.
We conclude that the use ofmobile phone has a negative effect onJetaL heart so we recommend avoidance ofceLLuLar phone use especiaLly in the earLy weeks of gestation and if necessary, the phone caLL should be Less than ten minutes. |
