I	B‐NR	1. In patients with known or suspected VA, echocardiography is recommended for evaluation of cardiac structure and function.	S3.2.2.3–S3.2.2.4
IIa	B‐NR	2. In patients presenting with VA who are suspected of having SHD, even after normal echocardiographic evaluation, advanced cardiac imaging can be useful to detect and characterize underlying SHD.	S3.2.2.5–S3.2.2.7
IIa	C‐EO	3. In patients with VA in whom myocardial ischemia is suspected, stress testing and/or coronary angiography and subsequent revascularization can be beneficial before catheter ablation to avoid significant ischemia during induced VT.
III: No Benefit	B‐NR	4. In patients presenting with monomorphic VT, revascularization alone is not effective to prevent VT recurrence.	S3.2.2.8–S3.2.2.10
