Jun 8, 2023 · ECG Features of Anterior STEMI. ST segment elevation with subsequent Q wave formation in precordial leads (V1-6) +/- high lateral leads. These changes are often preceded by hyperacute T waves. Reciprocal ST depression in inferior leads (mainly III and aVF)

Tombstoning ST elevation myocardial infarction can be described as a STEMI characterized by tombstoning ST-segment elevation. This myocardial infarction is associated with extensive myocardial damage, reduced left ventricle function, serious hospital complications and poor prognosis.
Nov 10, 2019 · ECG characteristics for tombstone STEMI are as follows: i. Absent R wave or an R wave duration of <0.04 second with minimal amplitude. ii. Convex upward ST segment merging with descending R or the ascending QS/QR. iii. Peak of ST-segment is higher than the R wave. iv. ST-segment merges with the T wave.
What is a Tombstoning ECG and Why Does it Matter? In the practice of medicine, we often hear the term Tombstoning ECG. But what does it reference generally and why does it matter? The term tombstoning is used to reference the eerie appearance of the ST segment elevation seen in the 12-lead ECG of a patient having an Acute ST Elevation MI (aka ...
May 11, 2004 · Tombstone ST elevation is an unusual morphological ECG appearance of acute myocardial infarction. The ST segment is convexed upwards and the peak of the convexed ST segment is often higher than the preceding R wave, which is less than 0.04 s and small in amplitude.
Learn how to recognize and differentiate ST segment elevation in acute myocardial ischemia and other causes on ECG. See criteria, examples, pitfalls and natural course of STEMI.
Sep 10, 2018 · Our patient presented without chest symptoms yet with a concerning ECG with typical tombstone ST-elevations, suggestive of ongoing myocardial injury. These findings were followed by coronary angiography and echocardiogram, which were both negative for ischemia.
