Event Description
|
On (b)(6) 2017, the subject crt-d was implanted and connected to the previously implanted leads.Reportedly, on (b)(6) 2019, the sales representative was warned that the crt-d displayed a charge time of 0.3 seconds during the interrogation.Review of the patient files revealed that a shock of 42 joules was delivered on (b)(6) 2018.The physicians suspected that the shock was delivered because of electromagnetic interferences (emi), since noise was observed on both the atrial and ventricular channels.As the noise was intermittent, the capacitors could have been charging discontinuously until a shock was delivered.It was supposed that the charge time of 0.3 seconds was due to previous charging of the capacitors.Preliminary analysis revealed that the atrial and ventricular noise oversensing most probably resulted from electromagnetic interferences (emi).
