However, it had not been fully analysed that whether early alternations of electrocardiogram, including vectorcardiogram, could determine the long-term persistent heart conduct block.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951126123506_as2\">\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective study was conducted to develop a Random Forest-based prediction model for the postoperative of the transcatheter interventional closure.

The area under receiver operating characteristic curve values of such evaluations on the test sets were 0.9974, 0.9592, 0.9977, 0.9985, 0.9957, and 0.9977, recalls were 98.35%, 83.39%, 99.57%, 98.04%, 97.80%, and 99.58%. In the prediction model, the importance of features was ranked. We found that the diameter and number of occluder used in surgery and the size of left atrium and ventricle were the primary factors for predicting arrhythmia after surgery. For electrocardiogram data, significant parameters include RV5 voltage and the R\u2013T angle of the sagittal plane vectorcardiogram before the treatment, T-wave, R-wave, and QRS duration in early days after operation and RV1 voltage, R-wave axis during 1-month follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951126123506_as4\">\n
