cesium-induced arrhythmias were suppressed by the calcium antagonist diltiazem , magnesium chloride , beta blockade ( with atenolol ) , or vagal nerve stimulation -- all interventions that can suppress calcium entry . beta-adrenergic stimulation with isoproterenol initiated ventricular arrhythmias in the presence of subarrhythmic doses of cesium .
