ELECTROCARDIOGRAPHY (ECG) | PPT - SlideShare
2013年4月25日 · An ECG is a recording of the electrical activity of the heart over time using skin electrodes. It is the gold standard for diagnosing cardiac diseases in a noninvasive manner. The ECG records the P wave from atrial depolarization, the QRS complex from ventricular depolarization and repolarization of the atria, and the T wave from ventricular ...

ECG Rhythm Interpretation Normal EKG – P wave: Atrial depolarization – PR interval: < 0.20 sec – QRS complex: ventricular depolarization – QRS interval < 0.10 sec SA 0.10 – 0.12. Fast & Easy ECGs, 2nd E – A Self-Paced Learning Program
Compare these two 12-lead ECGs. What stands out as different with the second one? ST elevation > 1 mm in limb leads and > 2 mm in chest leads indicates an evolving acute MI until proven otherwise. Not perfect in screening for AMI. Use as another data point for risk-stratifying. Last night.... Questions?
