Idioventricular rhythm is a common "reperfusion arrhythmia." In other words, after reperfusion therapy for STEMI, the appearance of AIVR is usually a good sign, meaning that the artery is reperfused. The second explanation (AIVR), whether as a reperfusion dysrhythmia or not, seems most likely. But it is not conclusive.

So the real QT is shorter, but the computer does not mention the U-wave, and the U-wave is as important as the T-wave in predicting cardiac dysrhythmias. IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5 This is an extremely dangerous ECG.

IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5 malignant ventricular arrhythmias are present), rapid replacement of potassium is required. to greatly decrease risk (although in STEMI, the optimal level is about 4.0-4.5 If the patient is at 1.8,

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. 2 The astute paramedic recognized this possibility and announced a CODE STEMI. myocardial infarction), arrhythmias, valvular pathology, shunts, or outflow obstructions.

Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? Comments: STEMI with hypokalemia, especially with a long QT, puts the patient at very high risk of Torsades or Ventricular fibrillation (see many references, with abstracts, below). There is atrial fibrillation.

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. There were no dysrhythmias on cardiac monitor during observation. Induced Brugada-type electrocardiogram, a sign for imminent malignant arrhythmias. Is there fever again?

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab. Induced Brugada-type electrocardiogram, a sign for imminent malignant arrhythmias. Bicarb 20, Lactate 4.2,
