- What minimum ST-segment elevation in two or more contiguous limb leads meets STEMI criteria?
Show answer
At least 1 mm (0.1 mV)- What minimum ST-segment elevation in two or more contiguous precordial (chest) leads meets STEMI criteria?
Show answer
At least 2 mm (0.2 mV)- Which EKG leads show changes in an inferior wall MI?
Show answer
Leads II, III, and aVF- Which EKG leads show changes in an anterior wall MI?
Show answer
Leads V1 through V4- Which EKG leads show changes in a lateral wall MI?
Show answer
Leads I, aVL, V5, and V6- In a suspected inferior MI, which extra lead should be placed to check for right ventricular involvement?
Show answer
Lead V4R (right-sided V4)- Why is nitroglycerin withheld in a right ventricular infarction?
Show answer
The right ventricle depends on preload, so nitroglycerin can cause a severe drop in blood pressure- What EKG finding in leads V1-V2 suggests a posterior wall MI?
Show answer
ST depression with tall, broad R waves- What is the first-line drug for symptomatic bradycardia with a pulse?
Show answer
Atropine- What is the adult IV dose of atropine for symptomatic bradycardia?
Show answer
1 mg, repeated every 3 to 5 minutes up to a maximum of 3 mg- What intervention is used for symptomatic bradycardia that does not respond to atropine?
Show answer
Transcutaneous pacing- What is the first-line drug for stable narrow-complex SVT?
Show answer
Adenosine- What is the initial adult dose of adenosine for SVT?
Show answer
6 mg rapid IV push, followed immediately by a saline flush- What is the second dose of adenosine if the first dose does not convert SVT?
Show answer
12 mg rapid IV push- What bedside maneuvers can be tried before adenosine for stable SVT?
Show answer
Vagal maneuvers, such as Valsalva or carotid sinus massage
