How can I segment the ECG signal and giving its label?

I want to segment the signal and put the labels(for example Heartbeat: (AA, PAC, AE, NP, SVE, PVC, FS, RPV, LBB, RBB or N) premature ventricula contraction ----> pvc, ) to the signal

the time is as follow : from beginning time to the end time coreespond it for example pvc ,etc...

Note: the beginnig time for recording the ECG is began from the following time 15:35:47,15:35:56

15:35:56 to 15:36:06 ----> PVC

15:36:43 to 15:36:53 ----> PVC

15:37:14 to 15:37:24 ----> AA

15:37:41 to 15:37:52 ----> AE

and so on
