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

Dr. Smith's ECG Blog

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. 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.

What is the rhythm? And is there new left bundle branch block (LBBB)?

Dr. Smith's ECG Blog

Is there ischemia? Idioventricular rhythm is a common "reperfusion arrhythmia." ECG Diagnosis is either : 1) junctional rhythm with new LBBB, and possibly ischemia 2) accelerated idoventricular rhythm with possible ischemia, and possibly related to restoration of normal perfusion. But it is not conclusive.

Diffuse Subendocardial Ischemia on the ECG. Left main? 3-vessel disease? No!

Dr. Smith's ECG Blog

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

There were no dysrhythmias on cardiac monitor during observation. This discussion comes from this previous post: Hyperthermia and ST Elevation Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. He was found to be influenza positive. Is there fever again?

And superimposed subendocardial ischemia pattern, of course. Flecainide : This is a potentially dangerous Na channel blocker which can cause ventricular dysrhythmias including ventricular fibrillation. While these do not alter emergency management of this patient's arrhythmia — They should be noted.

STEMI with Life-Threatening Hypokalemia and Incessant Torsades de Pointes

Dr. Smith's ECG Blog

If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone. Could the dysrhythmias have been prevented? malignant ventricular arrhythmias are present), rapid replacement of potassium is required. Learning Points: 1.
