See this post: How a pause can cause cardiacarrest 2. 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. The plan: 1. Place temporary pacemaker 3.
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. He had multiple cardiacarrests with ROSC regained each time.
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.
The limb lead abnormalities appear to be part of the Brugada pattern, as described in this article: Inferior and Lateral Electrocardiographic RepolarizationAbnormalities in Brugada Syndrome Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias.
NOTE #3: In the context of a long QTc or ischemia — the finding of ST segment and/or T wave alternans may predict the occurrence of malignant ventricular arrhythmias.
