Before revision:  Ideally, non-invasive or minimally-invasive clinical data, such as the standard ECG or intracardiac contact recordings, could provide an insight on modelparameters. Parameter selection of such models is however a challenging and potentially time-consuming task.
After revision:  Ideally, non-invasive or minimally-invasive clinical data, such as the epicardial activation or the 12-lead electrocardiogram (ECG), due to the underlying complexity of the model.
