Upon receipt, the icd was interrogated, revealing the battery status bos.The icd was implanted for 34 months and 10 charging cycles were recorded to the devices memory.The memory content of the device was inspected.During the analysis of the available iegms noise was observed in the right ventricular channel, leading to one charging cycle.Therefore, a sensing test was performed and the device sensed the applied heart signals free of noise, proving the sensing function of the icd to be normal and as expected.There was no indication of a device malfunction.The header of the icd was inspected, revealing no anomalies.In a next step, the ability of the device to deliver therapies was verified.The anti-bradycardia pacing pulses proved to be normal and in amplitude and frequency as programmed.A fibrillation signal was applied and the device delivered a defibrillation shock as specified, documenting a normal and expected sensing and shock delivery.In particular, the specified energy level was reached.In conclusion, the memory content as well as the therapeutic functionality of the icd were inspected.In the available iegms the occurrence of noise was observed in the right ventricular channel, confirming the clinical observation.However, a thorough analysis of the icd proved the device to be fully functional.There was no indication of a device malfunction.
