Stepwise Approach to STAT ECGs Hub
Key Points: Use a consistent ECG routine. In acute care, a repeatable approach reduces misses and helps you recognize dangerous patterns faster. Prioritize life threats first. Instability, malignant rhythms, occlusion…
QRS Morphology and ST-T Interpretation: Basics
Key Points: Read the QRS before you read the ST segment or T wave. Ventricular depolarization shapes repolarization. Narrow QRS usually reflects normal His-Purkinje conduction. Wide QRS suggests abnormal ventricular…
STAT ECG 101: The Acute Care ECG Workflow
Key Points: The ECG is the fastest bedside test for rhythm, conduction, ischemia, and tox-metabolic disease. It only saves lives when interpreted systematically and acted on. In acute care, the…
R Wave: Basics
Key Points Definition: The R wave is the first positive deflection of the QRS complex, reflecting early ventricular depolarization, predominantly of the left ventricle. Normal progression: Precordial R amplitude increases…
Ischemia & Infarction Interpretation
Key Points: The ECG is the fastest bedside tool for detecting acute coronary occlusion and dynamic ischemia, often before troponin changes and sometimes before classic symptoms. Acute coronary syndromes are…
Heart Rate & Rhythm Interpretation
Key Points: Treat the patient, not just the number or rhythm. Start with a 10-second stability check. If the rhythm explains hypotension, shock, ischemic chest pain, altered mentation, or severe…
QRS Axis Interpretation: Basics
Key Points: Definition: The QRS axis reflects the net direction of ventricular depolarization and is expressed in degrees on the frontal plane. Why It Matters: Axis assessment is a fast,…
Interval Interpretation
Key Points: Intervals are your ECG safety rails. Before you get seduced by ST segments and T waves, lock down PR, QRS, and QT/QTc. They frequently reveal the real danger…
