Pacemakers
Pacemaker
work by giving an artificial signal to initiate contraction each time that the
heart fail to generate its own signal. They can be implanted quite easily under
local anesthetic. They consist of a small box of micro-electronic circuitry
powered by a small but very long-life battery (5-10 years) attached to a wire
whose tip is lodged within the heart. When we are exposed to an electromagnetic
field it generate electromagnetic interference (EMI) that can alter the function
of the pacemaker or implantable defibrillator). The intensity of EMI is higher
in condominiums than in single family houses and it increase at higher floors.
The most dangerous household appliances as a source of electromagnetic field
are: ice-cream machines, food grinders, washing machines (during spin-drying),
electric typewriters, electric blankets and electric shavers connected to power
line, carpet cleaners, vacuum cleaners, personal computers (especially the
monitors), air conditioner (single room, movable), hi-fi loudspeakers. Outside
and at work pay attention to. Powerful magnets, power generators, arc-welding
machines, cordless tools with metal handle, high-voltage power lines, melting
furnaces, radar stations, transmitting antennas of broadcasting and mobile phone
stations.
At the airport not let they place the portable metal detector close to
pacemaker implant site, not delay close to electronic gates or anti-theft
systems located at the exit of banks. Finally avoid magnetic resonance, positron
emission tomography (PET), electrocautery, radiotherapy, lithotripsy,
transcutaneous nerve stimulation, RF ablation, external defibrillation, external
and internal cardioversion, diathermy, electroacupuncture, magnetotherapy, Use
mobile phone of last generation with hear phone and maximum power of 2 watts and
do not carry the phone near the pacemaker.
