Are beta blockers & calcium channel blockers truly contradicted in Wolff-Parkinson-White patients?
Can beta blockers such as propranolol or toprol (metoprolol) help prevent ventricular fibrillation in susceptible individuals?
Sometimes: These are two totally different classes of drugs and depending on the mechanism by which your pvcs arise, a calcium channel blocker may indeed be more effective. If drugs fail you, an expert center and electrophysiologist may be able to perform a PVC ablation to eliminate the beats from within the heart, but such procedures require a skilled electrophysiologist for the best chance at good results. ...Read moreSee 1 more doctor answer
Are these drugs used to reduce cardiac output: calcium channel blockers and beta (receptor) blockers?
They often can: Ectopic beats are heart beats that originate from a location in the heart other than the normal sinus node in the atrium(the normal pacemaker). If they originate in the atrium they are called premature atrial contractions(PACs). If they originate from the ventricle they are called(PVCs). Beta blockers can reduce or prevent PACs and can reduce the symptoms from frequent PVCs. ...Read moreSee 1 more doctor answer
