Predictors of VA during the study period
The main predictor of any VA during the COVID-19 epidemic period was previous history of any ICD therapy (OR 3.54, p < 0.001) and recent (<12 months) history of ICD interventions either with ATP or shock (OR 9.15, p < 0.001). Age, sex, pharmacologic therapy or secondary prevention indication were not found to be predisposing factors for arrhythmic events during the study period. (see Table 3 – univariable and multivariable logistic regression analysis).
Among men, the incidence of VA was similar in the study period to the reference period (34 vs 26 events in a sample of 342 males, χ2 =0.034, p = 0.851).
