…occlusion, likely because most such occlusions result in prehospital cardiac arrest and death. As in other acute coronary events, the thrombotic process is dynamic, with…

…be normal (QRS duration <0.12 s), because both bundle branches receive the impulse and spread it. If the impulse is discharged distal to the…

…near the bundle of His, the impulse may be delivered to both bundle branches and subsequently the entire ventricular myocardium normally. This may yield a…

…length Large thrombotic burdens increase procedural risk because thrombus can fragment, embolize to other coronary branches or vascular beds, propagate through gaps between stent struts…

…of ischemia (but the sensitivity is low). U wave changes always accompany other ischemic ST T changes. They may occur in both NSTEMI and STEMI…

…To address these challenges, researchers have developed ECG criteria designed to identify ischemia in the presence of left bundle branch block. The most widely recognized…

Cardiology Introduction Since its initial description in 1992 as a syndrome of right bundle branch block, ST segment elevation, and sudden cardiac death (SCD), Brugada…

…or arteries supplying the limbs. In adults over 40 years of age, atherosclerosis is the predominant cause. Other mechanisms include thrombosis, embolism, vasculitis, fibromuscular dysplasia…
