Torsade in a patient with left bundle branch block: is there a long QT? (And: Left Bundle Pacing).

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. Smith, this can be accomplished by either using beta-one agonists or temporary transvenous pacing.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. Between 81-95% of life-threatening ventricular dysrhythmias and acute cardiac failure occur within 24-48 hours of hospitalization. No cardiac MRI was done.

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. The rhythm is atrial fibrillation. The QRS complex is within normal limits.

Syncope, chest pain, and inferior ST Elevation with Reciprocal ST depression in aVL

Doesn't this necessarily mean that he was having ischemia? He was admitted for monitoring and had no dysrhythmias. But vasovagal syncope typically has a prodrome such that further evaluation of today's patient may be needed as an outpatient to better assess for the cause of his sudden syncope. She is very good.
