Electrochemotherapy of colorectal liver metastases - an observational study of its effects on the electrocardiogram

Table 5 Correlation between changes in the ECG and HRV parameters and the EP pulse delivery parameters.

Compared parameters	No. of delivered EP pulses	Average U applied to tumors	Average I applied to tumors	Total energy applied to patient
Δ mean NN	0.919	0.399	0.210	0.154
Δ LF	0.026	0.315	0.522	0.953
Δ nLF	0.239	0.616	0.271	0.060
Δ nHF	0.239	0.616	0.271	0.060

Correlation was evaluated for ECG and HRV parameters with statistically significant change after ECT from Table 4. Values of p (statistical significance of the correlation) are given in the table.
