It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. Smith, this can be accomplished by either using beta-one agonists or temporary transvenous pacing. J Am Coll Cardiol.

Not all forms of idiopathic VT are predictable based on their ECG appearance ( Anderson et al, 2019 ). Anderson et al, 2019 ) — the chest lead LBBB pattern characteristic of LVOT ( as distinguished from RVOT ) — is that transition tends to occur earlier ( ie, by V1-V2 for LVOT vs after V3 or V4 for RVOT ).
