Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. 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.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). Chest trauma was suspected on initial exam.

There’s sinus bradycardia, first degree AV block, normal axis, delayed R wave progression, and normal voltages. Hyperacute T waves are deflating, suggesting reperfusion but there is still reciprocal change in I/aVL and ST depression in V2, and the bradycardia is worse. Below is the ECG. What do you think? See analysis below.
