What do tombstones mean on an ECG?
Tombstoning ST-segment elevation is a type of ST-segment elevation with a specific morphology which is observed in the early period of acute myocardial infarction [2-7]. This ECG appearance is a notion beyond morphological difference and is associated with more serious clinical results.
What is a tombstone heart attack?
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.
What is the J point?
Introduction. The J point denotes the junction of the QRS complex and the ST segment on the electrocardiogram (ECG), marking the end of depolarization and beginning of repolarization.
What does a STEMI look like on EKG?
Classically, STEMI is diagnosed if there is >1-2mm of ST elevation in two contiguous leads on the ECG or new LBBB with a clinical picture consistent with ischemic chest pain. Classically the ST elevations are described as “tombstone” and concave or “upwards” in appearance.
What does tombstone mean in medical terms?
Also found in: Dictionary, Thesaurus, Financial, Encyclopedia. A term of art used by some cytopathologists for the large, tall and markedly atypical isolated cells seen by aspiration cytology in moderately to poorly differentiated adenocarcinomas.
What does AJ wave mean?
Abstract. The “J wave” (also referred to as “the Osborn wave,” “the J deflection,” or “the camel’s hump”) is a distinctive deflection occurring at the QRS-ST junction. In 1953, Dr. John Osborn described the “J wave” as an “injury current” resulting in ventricular fibrillation during experimental hypothermia.
What does AJ point elevation mean?
Mihalick, MD. Dear AJ, The term J-point elevation represents a family of ECG findings. It has been described in several metabolic disorders most notably hypothermia (abnormally low body temperature). Subtle nuances in its pattern may point to other conditions, the most common of which is termed ‘early repolarization’.
Which artery is blocked in a STEMI?
A STEMI is a full-blown heart attack caused by the complete blockage of a heart artery.
How do I know myocardial infarction?

- shortness of breath.
- sweating.
- nausea.
- vomiting.

What does a tombstone ad do?
A tombstone is a written advertisement of a public offering placed by investment bankers who are underwriting the issue. It gives basic details about the issue and lists each of the underwriting groups involved in the deal.
What is the ST elevation of a tombstone?
Tombstone ST elevation. Overview. Tombstone ST elevation is an electrocardiographic pattern of ST segment elevation whereby the QRS complex, the ST segment and the T wave merge to form a large upright monophasic deflection called a “tombstone”.
What kind of deflection is a tombstone?
Tombstone ST elevation is an electrocardiographic pattern of ST segment elevation whereby the QRS complex, the ST segment and the T wave merge to form a large upright monophasic deflection called a “tombstone”.
Is the anteroseptal STEMI ECG a tombstone?
The anteroseptal STEMI ECG example below is good enough to call a tombstone in lead V3. There is no lateral involvement here. Although not quite a tombstone, there is still significant ST segment elevation here. The ST segment elevation barely reaches 5 mm in V3, and there is a bit of ST segment elevation laterally in lead V5 and V6.
What kind of ECG is tombstoning ECG?
Tombstoning ECG pattern is a notion beyond morphological difference and is associated with more serious clinical results. LAD=left anterior descending coronary artery; TIMI=thrombolysis in myocardial infarction; PCI=percutaneous coronary intervention.
