I find AV dissociation in VT to be very difficult to differentiate from artifact, as there are always random blips on tachycardia tracings. If you don't know what the dysrhythmia is, then try procainamide. Read this post: Idiopathic Ventricular Tachycardias for the EM Physician 2. Ken notes AV dissociation. What to do now?

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. See these publications for more information Overall, management for cardiac contusion is mostly supportive unless surgical complications develop, involving appropriate treatment of dysrhythmias and hemodynamic instability.

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. Now the patient is in sinus tachycardia. Her initial EKG is below. Same as initial ECG.

Then there is loss of pulses with continued narrow complex on the monitor ("PEA arrest") Learning Points: Sudden witnessed Cardiac Arrest due to ACS is almost always due to dysrhythmia. Tachycardia is of course, quite common in patients following cardiac arrest. This patient arrested shortly after hospital arrival.
