2024年10月8日 · There is widespread concave ST elevation suggesting pericarditis. However, the ST elevation is markedly more prominent in the precordial leads (esp. V2-5), consistent with BER. There appears to be some subtle downsloping PR depression in the limb (I, aVL) and precordial leads (V3-6), with subtle PR elevation in aVR, suggesting pericarditis.

2024年11月5日 · Concave or saddle-shaped, often following J-point elevation. STE is greatest in II and V5-V6. STD in aVR. No reciprocal STD (especially in aVL). Upright, relatively small T-waves (in V6, STE is >25% height of the T-wave). PR …

2024年10月8日 · Concave “saddleback” ST elevation in leads I, II, III, aVF, V5-6 with depressed PR segments. There is reciprocal ST depression and PR elevation in leads aVR and V1. Spodick’s sign was first described by David H. Spodick in 1974 as a downward sloping TP segment with specificity for acute pericarditis.

2018年11月9日 · The shape of the ST elevation in leads V1 and V2 in ECG #1 is concave up, which is usually a benign morphology. As per Dr. Smith — the “saddleback” configuration (seen best here in lead V2) is rarely due to acute MI. Apart from leads V1 and V2 — there really is no abnormal ST segment deviation.

2024年10月22日 · Brugada Type 2 has >2mm of saddleback shaped ST elevation. Brugada type 3: can be the morphology of either type 1 or type 2, but with <2mm of ST segment elevation. The only proven therapy is an implantable cardioverter – defibrillator (ICD).

2023年4月5日 · Convex shaped ST segment elevation is more likely to indicate STEMI (Level of evidence Grade 2b). Ventricular aneurysm, like STEMI, manifests as ST segment elevation that is territorial in distribution; however, unlike STEMI, it is static.

In type 2 and type 3 Brugada syndrome, the ST segment elevation is saddleback shaped (panels B and C, Figure 10). The difference between type 2 and type 3 is that the ST segment elevation in type 2 is elevated ≥2 millimeters (it is lower in type 3 Brugada syndrome).

2022年2月13日 · 12-lead ECG: typical findings are widespread ‘concave/saddle shaped’ ST-elevation except in aVR and often V 1, PR segment depression; low voltage QRS complexes/‘electrical alternans’ indicates significant pericardial effusion. These ECG changes reflect myocardial involvement as the pericardium is electrically inert.

Several characteristic ECG changes occur during the natural history of a STEMI. This refers to inflammation of the lining of the heart known as the pericardium. It leads to classic saddle-shaped ST elevation that is widespread and not related to a coronary artery territory. The other salient feature is PR depression.

A prominent coved or saddle-shaped ST-segment elevation followed by T wave changes in V1-V3 and in the absence of other identifiable cause is termed as Brugada pattern.
