Normal Sinus Rhythm
Results:
Normal Cardiac Conduction
Key Points SA Node: Initiates electrical impulses; primary pacemaker (60–100 bpm). AV Node: Slows conduction to permit ventricular filling. Bundle of His: Transmits impulses from the AV node to ventricles;…
Normal STAT ECG
Key Points Clinical Context: A normal 12-lead ECG in acute settings does not exclude life-threatening pathologies (e.g., occlusion myocardial infarction [OMI], pulmonary embolism [PE], cardiac tamponade, tension pneumothorax, aortic dissection)….
Normal Sinus Rhythm
Key Points Definition: Normal sinus rhythm (NSR) refers to the heart’s rhythm when impulses originate from the sinoatrial (SA) node, the heart’s primary pacemaker. This rhythm suggests that electrical impulses…
ECG Basics & Fundamentals: A stepwise approach to ECG interpretation in patients with chest pain and clinical concern for an acute coronary syndrome (ACS) with pearls and pitfalls in obtaining chest pain histories
HPI: 61 year old male with significant cardiac risk factors presents with chest pain that that radiates down both arms. The pain is exertional and improves with rest. His pain…
