during which sinus bradycardia and arrhythmia are seen but not to a degree that produces symptoms. Thus, there is sinus bradycardia and arrhythmia sinus pauses ( which may be longlasting, ultimately leading to sinus arrest ) and SA nodal block.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). Chest trauma was suspected on initial exam. Here is his initial ECG around 1330: What do you think?
