ICMP patient with single chamber ICD for sec prevention. EGM of the stored episode in the device memory, labelled as NSVT. Do you agree with the diagnosis?

Initially narrow complex short RP tachycardia (manifested as pseudo R in V1) with TCL around 380 msec likely AVNRT, then CL became double & obvious P midway btween RR because of 2:1 block at LCP, again becomes 1:1 with LBB abberency due to long short sequence.

Wide complex RBB tachycardia transitioning to narrow in the later part (restitution) TCL remains same during narrow and fast(VT & right sided AP ruled out). Rhythm is supraventricular, mechanism unclear with single trace, they gave amiodarone and the answer revealed. 👇👇👇
