    Narratives

    Additional Manufacturer Narrative · 1

    A REVIEW OF THE LATITUDE WEBSITE CONFIRMED THAT THE SHOCK IMPEDANCE MEASUREMENTS HAVE RANGED FROM 80 TO ABOVE 125 OHMS. IT WAS ALSO CONFIRMED THAT THE MEASUREMENTS DID GO ABOVE 125 OHMS ON TWO OCCASIONS WHICH BOTH TRIGGERED RED ALERTS. THE TS REPRESENTATIVE DISCUSSED THAT A REVIEW OF THE MEASUREMENTS SHOW THAT THE SHOCK IMPEDANCES HAVE ARE WITHIN THE UPPER RANGE, MOST LIKELY DUE THE DEFIBRILLATION LEAD BEING A SINGLE COIL LEAD. THE MEASURED IMPEDANCES CAN CHANGE MORE THAN 20 OHMS ON A DAY TO DAY BASIS, MAKING IT POSSIBLE TO HAVE THE MEASURED VALUES CROSS THE 125 OHMS MEASUREMENT AND TRIGGER A RED ALERT. AT THIS TIME, THE DEVICE AND LEAD REMAIN IMPLANTED AND IN SERVICE. NO ADDITIONAL INFORMATION IS AVAILABLE. AS NO FURTHER INFORMATION CONCERNING THIS REPORT IS EXPECTED, OUR INVESTIGATION IS COMPLETE. THIS INVESTIGATION WILL BE UPDATED SHOULD FURTHER INFORMATION BE PROVIDED.
