Pericardial, Myocardial, and Pulmonary Syndromes Flashcards
The early phase of acute pericarditis is usually characterized by ?
ST segment elevations.
A major difference between ST elevations asscociated with MI and those associated with acute pericarditis ?
ST-T changes occuring with pericarditis are usually more generalized and seen in both anterior and inferior lead distributions.
What triad is virtually diagnostic of cardiac tamponade ?
Sinus tachycardia, electrical alterans, and low QRS voltage.
ECG findings in pulmonary embolism ?
Sinus tachycardia at rest, arrhythmias such as ventricular ectopy and atrial fibrillation or flutter, inverted T waves in leads V1 to V3 to V4, S1Q3T3 pattern, shift of QRS axis to the right, ST depressions, a new complete or incomplete RBBB, a qR complex in V1, tall peaked P waves in the inferior leads.
