![]() ![]() If you have an Exclusion, select “No,” regardless of other documentation, and there is no need to review further. Determine if the terms or phrases are Inclusions or Exclusions. Start with review of your SIGNED tracing.If unable to determine which ECG was performed closest to arrival, select “No.” ![]() Identify the ECG performed closest to arrival, either before or after hospital arrival, but not more than 1 hour prior to arrival.N (No) No ST-elevation or LBBB on the interpretation of the 12-lead ECG performed closest to hospital arrival, no interpretation or report available for the ECG performed closest to hospital arrival or unable to determine from medical record documentation. Y (Yes) ST-segment elevation or a LBBB on the interpretation of the 12-lead ECG performed closest to hospital arrival. Is there documentation of ST-segment elevation or left bundle branch block (LBBB) on the electrocardiogram (ECG) performed closest to hospital arrival? LBBB may be an electrocardiographic manifestation of an AMI. In LBBB, left ventricular depolarization is delayed, resulting in a characteristic widening of the QRS complex on the ECG. A bundle branch block (BBB) results from impaired conduction in one of the branches of the conduction system between the atria and the ventricles, which in turn results in abnormal ventricular depolarization. The ST-segment, the segment between the QRS complex and the T wave, may be elevated when myocardial injury (AMI) occurs. The normal ECG is composed of a P wave (atrial depolarization), Q, R, and S waves (QRS complex, ventricular depolarization), and a T wave (ventricular repolarization). ST-segment elevation or a left bundle branch block (LBBB) based on the documentation of the electrocardiogram (ECG) performed closest to hospital arrival. ![]()
