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

Dr. Smith's ECG Blog

A 90 yo with a history of orthostatic hypotension had a near syncopal event followed by chest pain. Chest pain was resolved upon arrival in the ED. In other words, after reperfusion therapy for STEMI, the appearance of AIVR is usually a good sign, meaning that the artery is reperfused. His previous ECG was normal.

He denied chest pain or shortness of breath. In the clinical context of weakness and fever, without chest pain or shortness of breath, the likelihood of Brugada pattern is obviously much higher.

It is equivalent to a transient STEMI. Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. As emphasized by Dr. Smith — the best way to demonstrate acute ischemia is by identifying d ynamic S T- T wave c hanges in association with change in the nature of chest pain.
