Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. The plan: 1.

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.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades.

Opinions vary widely on the K level at which a patient must be admitted on a monitor because of the risk of ventricular dysrhythmias. My rationale is that if the K is affecting the ECG, then it is affecting the electrical milieu and can result in serious dysrhythmias. Until some real data is available, my opinion is this: 1.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. She was ventilated by bag-valve-mask by EMS on arrival and was quickly intubated with etomidate and succinylcholine. A rectal temperature was obtained which read 107.9

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
