class Ia
antiarrhythmics(sodium channel blocker+potassium channel blocking effects as well)
SVT treatment(supraventricular tachycardia)
β blocker, Ca blocker(blocks AV node),adenosine
+vagal maneuver,cardioversion,ablation
Ca blocker is contraindicated with pseudoVT(WPW+AF),retrograde AVRT
(when AV node is blocked, retrograde AVRT will be aggravated) cardiology Jun 20, 2019, 2:46 AM HirotoShishido
