Situations in which SVT can be dangerous

Situations in which supraventricular tachycardia (SVT) can be dangerous:
Usually SVT is an arrhythmia which is well tolerated and patients seldom go into hemodynamic compromise with SVT. But in certain situations, SVT can be dangerous, if it is associated with:

Hypertrophic cardiomyopathy
Acute coronary syndrome  (ACS) – increased myocardial oxygen demand worsens ACS
Inoperable severe coronary artery disease – increased myocardial oxygen demand worsens ischemia
SVT requiring high dose antiarrhythmic agent for suppression – severe bradycardia can occur after termination of SVT
