Reportedly, the patient came to the hospital in the night between (b)(6) 2016 because of lipothymia.The subject icd was programmed in safer-r mode, and the cardiologist suspected that the patient was sensitive to avb commutations.Since the patient has a severe cardiac condition, the cardiologist wants to avoid ventricular stimulation.Therefore he reprogrammed the icd in ddd mode with an av delay of 205ms.On (b)(6) 2016, the patient was ready to be discharged, but then he collapsed.It was reported that he was in asystolia, he received an external cardiac massage and drugs and was hospitalized again.The medical team used an external monitoring device to check patient's cardiac rhythm.Atrial pacing was reportedly observed, but there was no ventricular activity.Upon icd interrogation and during tests, no anomaly was reportedly observed.The cardiologist wants to know what caused the asystolia and how to reprogram the icd to avoid it, and to avoid as well ventricular pacing.
