What's the strongest magnetic field safe for someone with a pacemaker ?

In summary, there are no hard standards for the strongest magnetic field safe for a man with a pacemaker. Risks vary depending on the pacemaker model. If the question is in relation to MRI scanning, there is technically no safe field due to the rapidly changing intensity that can induce potential in the pacemaker wires. However, a new pacer from Medtronic may offer a solution to this problem. Further research is needed to determine the progress of this device.

Hello i want to know what's the strongest magnetic field safe for a man who has pacemaker without having any problems ?

If it's not to complicated to answer, thank you.

If your post is in relation to MRI scanning, technically there is no safe field. The problem with MRI arises from the fact that the field is rapidly changing in its intensity at any given point. This induces a potential in the pacemaker wires. Since pacer wires are relatively long there is a fair amount of electrical energy generated in them and that energy is dumped at both ends of the wire- into the pacer and into the heart- not a good thing for either.
There is a new pacer from Medtronic that is a likely solution for the problem. I need to do some research and find out how far along that device is.
 

What is a pacemaker?

A pacemaker is a small medical device that is implanted in the chest to help regulate the heart's rhythm. It uses electrical pulses to keep the heart beating at a normal rate.

How does a pacemaker react to magnetic fields?

Pacemakers are generally safe around small, everyday magnetic fields, but strong magnetic fields can interfere with the functioning of the pacemaker. This can cause the heart to beat too fast or too slow, which can be dangerous for the patient.

What is considered a strong magnetic field?

A strong magnetic field is typically anything greater than 10 gauss. This can be found in some industrial settings, medical equipment, and certain household appliances like microwave ovens.

What precautions should someone with a pacemaker take around strong magnetic fields?

People with pacemakers should avoid direct contact with strong magnetic fields and keep a safe distance of at least 6 inches (15 cm) from the source. They should also avoid staying near the source for prolonged periods of time.

Can a strong magnetic field permanently damage a pacemaker?

In most cases, a strong magnetic field will not permanently damage a pacemaker. However, it can interfere with the device's functioning, and the pacemaker may need to be reset or reprogrammed by a doctor.
