Progressive epicardial coronary blood flow reduction fails to produce ST-segment depression at normal heart rates. Am J Physiol Heart Circ Physiol 2006; 291: H2889-96.de Chantal M, Diodati JG, Nasmith JB, Amyot R, LeBlanc AR, Schampaert E, Pharand C. Progressive epicardial coronary blood ...
St. John's wort has been approved since 1984 by the German Commission E for the treatment of anxiety, depression, and insomnia. Although it fell into disuse for a time, a renewed interest, especially in Western countries, has led to use as a component of numerous preparations for treating ...
【Abstract】 ObjectiveTo assess the relationship between reciprocal ST segment depression(R-ST-D) and pathalogical changes of coronary arteries in acute myo cardial infarction(AMI).MethodsPTCAs were performed during 2 to 8 hours after attacking of AMI in 40 patients with first single-focus AMI. ...

(A)Shows stable normal sinus rhythm without ST-segment shift at baseline 30 h after medical device implant. (B)Heart rate-related (heart rate increase from 119 at baseline to 148 beats/min) ST-segment depression sets off a “see your physician” alert 13 h after copper stent implantation ...
The Aslanger pattern was defined as (1) any ST elevation in lead III, but not in other inferior leads, (2) ST depression in any of the leads V4 to V6 (but not in V2) with a positive or terminally positive T-wave, and (3) ST in...
(28/40)vs 90.0%(36/40)],the difference wasstatistically significant(P=0.025),so as the LD boundary proximal LAD occlusion had a higher positive predictive value.STⅡ,Ⅲ,aVF depression≥0.1 mV judged the occlusion site in the recent opening of D1 or LD of the LAD,in the sensitivity of ...
Retrospective review of the index ECG indicated that 24 patients (1.8%) did not have diagnostic ST-segment elevation but instead had ST-segment depression, T-wave inversion, or nonspecific ST-T changes, including 3 patients with positive biomarker results (2 with non-STEMI and 1 with a drug ...
Briefly, we included NSTEMI patients with acute chest discomfort, elevation of cardiomyocyte necrosis biomarkers, ECG characteristics (transient ST-segment elevation, persistent or transient ST-segment depression, flat or inverted T waves, pseudo-normalization of T waves, or normal ECG) [14]. Risk ...
It should be noted that ST-segment depression in the anterior leads with early precordial transition could indicate ST elevation posterior wall MI, particularly if associated with ST elevation in the inferior leads (inferoposterior MI). Right-sided precordial leads can be helpful in patients ...
