What diagnosis is suspected by this ECG in a 78 year old male with 2 weeks of worsening SOB?

What is LV aneurysm
What is Beck's triad and what would you expect to see on ECG with this condition?
hypotension, jvd, muffled heart sounds (pericardial tamponade). Low voltage QRS complexes, diffuse ST elevation, and PR-segment depression (due to pericardial inflammation). Also can see electrical alternans, where there is beat-to-beat variation in the amplitude of the R waves
Name the three criteria for MI diagnosis based on Sgarbossa's Criteria
• Concordant ST-segment elevation greater than 1 mm (same direction as the QRS complex) (5 points)
• ST-segment depression of greater than 1 mm in lead V 1, V2, or V 3 (3 points)
• Discordant ST-segment elevation greater than 5 mm (opposite direction of the QRS complex) (2 points)
--> An accurate diagnosis of ischemia requires a minimum score of 3.

Name 8 contraindications to thrombolytic therapy in MI
What are: • Strong suspicion for aortic dissection or pericardial tamponade • Active gastrointestinal or other internal bleeding • Known structural cerebrovascular lesion such as AVM or aneurysm • Known malignant intracranial neoplasm • Ischemic stroke within 3 months • Previous intracranial hemorrhage • Intracranial procedure or head injury within past 3 weeks • Known severe bleeding disorder such as a coagulation abnormality (hemophilia, von Willebrand disease) or severe thrombocytopenia
Relative contraindications include: • Traumatic or prolonged(>10 min) CPR or recent (<3 weeks) major surgery such as coronary artery bypass graft, obstetric delivery, organ biopsy, previous puncture of noncompressible vessels • Gastrointestinal or genitourinary bleeding within the past 10 days • Older than 75 years • Severe uncontrolled hypertension (systolic >180 mm Hg, diastolic > 110 mmHg) • Hemostatic defects from systemic disease such as hepatic cirrhosis, severe renal insufficiency, malignancy • Current use of anticoagulant medications with INR above 1.7 or PT longer than 15 seconds • Pregnancy • High likelihood of left heart thrombus or subacute bacterial endocarditis • Diabetic hemorrhagic retinopathy or other hemorrhagic ophthalmic condition
Name one drug that would require you to increase the dose of adenosine and one drug or condition that would increase the effects of adenosine.
Increase dose (decreased effects): Adenosine is antagonized by the methylxanthines (theophylline, caffeine) since they prevent binding of adenosine at receptor sites
Decrease dose (inc effects): Dipyridamole, carbamazepine, diazepam, and cardiac transplant potentiate the effects of adenosine
