19 Technologie Défibrillateurs 1.Beeper A warning beeper indicates a low battery or another problem that a doctor should check out. There are no warnings to signal a large shock to the patient. 2.Battery The special batteries, made of lithium silver vanadium oxide, last six years or more, even though they have less energy than a standard laptop battery. 3. C.P.U. The processor chip analyzes electrical signals from the heart and determines whether any shocks are necessary. The chip runs at less than 100 kilohertz, making it more energy efficient 4. Antenna Communication between the I.C.D. and the programmer is made through low-frequency radio waves sent from the unit's antenna to a doughnutshaped receiver held over the patient's chest. 5. Connectors A lead with three connections provides sensing capabilities and a pathway for high-energy shocks to one of the heart s lower chambers. A second lead with only one connection provides sensing and pacing to an upper chamber. 6. Casing The I.C.D. is encased in titanium. Scar tissue grows around it, locking it in place. The device is sealed shut to prevent leakage, so when the battery dies, the entire device must be replaced 7. Memory The pattern of heart activity before, during and after disturbances is recorded 8. Leads Flexible wires convey sensing information to the I.C.D. and carry electric shocks to the heart. A patient may receive one or two leads depending on the nature of the heart problem. They are covered with silicone insulation. 9. Capacitors Similar to the ones used in camera flashes, capacitors can take up to 10 seconds to draw enough energy from the battery for a large jolt. Charge times for smaller shocks are much shorter. 10. Transformer For serious heart disturbances requiring a higher shock, a transformer converts low-voltage battery power into a higher voltage.

The processor chip analyzes electrical signals from the heart and determines whether any shocks are necessary. The chip runs at less than 100 kilohertz, making it more energy efficient 4.

29 Surveillance de la Surcharge Pulmonaire Optivol La surveillance de l apparition d une surcharge pulmonaire repose sur l analyse des modifications de l impédance intrathoracique mesurée par le dispositif implanté

30 Surveillance de la Surcharge Pulmonaire Optivol Pulmonary Congestion As fluid accumulates in the lungs, intrathoracic impedance decreases

31 Surveillance de la Surcharge Pulmonaire Optivol Normal Lungs As the lungs clear, intrathoracic impedance increases

32 Intrathoracic Impedance Measurements Optivol The impedance is measured from the device can to the RV Coil every 20 minutes from noon until 5 pm

33 Fluid Trends Optivol OptiVol Threshold OptiVol Fluid Index: Accumulation of the difference between the Daily and Reference Impedance Reference Impedance adapts slowly to daily impedance changes Daily impedance is the average of each day s multiple impedance measurements

Living with Your Pacemaker

Living with Your Pacemaker Brief Statement Additional Device Information An implantable pacemaker system relieves symptoms of heart rhythm disturbances. They do this by restoring normal heart rates. A normal heart rate provides
