Can be calculated ventricular rate from following data?

[Arveno]

I googled on difference between heart rate and ventricular rate and how it can be calculated. On the copy of ecg performed yesterday at cadiologists clinic I can see following : RR 688 ms , P 0 ms, PQ 0 ms, QRS 86 ms,

QT 358 ms, QTcB 432 ms. P- axel 0, QRS-axel -36, T-axel 34, HF 87/min. Acording to Googled medicine article it is possible to count the ventricular rate. Does those numbers give you some information about ventricular rate? She did not give answer to our questions. Please help. Thank You in advance
