An 82-year-old male presented to ED with SOB and acute heart failure. He has a history of heart failure and atrial fibrillation. What is the most likely cause of this ECG?
a) Subendocardial ischemia
b) Digoxin effect
c) Hypocalcemia
d) Hypokalemia
b) Digoxin effect
A 60-something male presented to the ED with weakness and fatigue. He was diagnosed with a viral syndrome and discharged. He returned later and had a lab and ECG workup. He had no cardiac history. There was no chest pain or shortness of breath. Which of the following findings can be seen on this ECG?
a) Hypokalemia
b) Hypothermia
c) Hypercalcemia
d) Digoxin effect
c) Hypercalcemia
A middle-aged female with type 2 diabetes presented to her endocrinologist for a regularly scheduled follow up appointment for diabetes management. During the appointment she complained of several days of off and on dizziness and bilateral leg weakness. On initial exam in the ED she complained of sharp intermittent chest and abdominal pains, increased weakness from baseline, and anxiety and tearfulness concerning her overall quality of life given her recent illnesses. Her initial ECG is shown. Based on this ECG, what is the most likely cause of her symptoms?
a) Hypocalcemia
b) Hyperkalemia
c) Anterior STEMI
d) OMI in wraparound LAD
b) Hyperkalemia
45 minutes after arrival, the patient from Question 6 was suddenly noted to have intermittent periods of obtundation alternating with respiratory distress and worsening pain. A new ECG is obtained.
Which of the following pathologies is noted on this ECG? Select All that apply.
a) Artefact
b) Hyperkalemia
c) CPR
d) “Shark-fin” STEMI
e) VT
b) Hyperkalemia
A 56-year-old male was found unresponsive by his relatives at home. It was an unknown the time that he had been unconscious. When the emergency medical services arrived, patient was found to be in pulseless electrical activity (PEA). Patient achieved return to spontaneous circulation (ROSC) 15 minutes after initiation of advanced cardiac life support protocol. What is the most likely cause of this ECG?
a) Cerebral infarct
b) Sodium channelopathy
c) LAD stenosis
d) Inferior STEMI
a) Cerebral infarct
This 59-year-old woman presented with palpitations, nausea, vomiting, weakness, and numbness. The following ECG is taken on initial assessment.
What is the most likely diagnosis of her symptoms based on this ECG?
a) aMI
b) LBBB
c) Hyperkalemia
d) Digoxin toxicity with bidirectional VT
d) Digoxin toxicity with bidirectional VT
A 72-year-old female patient presented to the ED with weakness, decreased urine output, and vomiting. Her initial ECG is as shown.
Which of the following is the most likely cause of these ECG changes?
a) Hypocalcemia
b) Hypokalemia
c) Hyperkalemia
d) Hypercalcemia
a) Hypocalcemia
A 59-year-old woman with diabetes, hypertension, prior stroke, and peripheral vascular disease presented with multiple near-syncopal events over the past 2 days, as well as ongoing back pain. EMS found her bradycardic in the 40s and administered atropine with no response. She was mentating and had a reasonable blood pressure (around 90s systolic), so they decided not to pace prehospital. On arrival the patients blood pressure was 79/50 mm Hg. She was still awake and alert. Here is her first ECG. What pathology is apparent on this ECG?
a) Hypocalcemia
b) Hyperkalemia
c) Pulmonary embolus
d) Hypokalemia
b) Hyperkalemia
An 89-year-old male presents to the ED with generalized weakness. His initial ECG is as shown. What is the most likely cause of these ECG changes?
a) Hypokalemia
b) Digoxin effect
c) Hypomagnesemia
d) Hypocalcemia
a) Hypokalemia
An 82-year-old woman with a history of GERD and congestive heart failure presented to the ED with two days of generalized weakness. Home Rx include omeprazole and Lasix (stopped 1 month ago for hypokalemia). Her initial ECG is as shown. What is the most likely cause of her symptoms based on this ECG?
a) Sodium channel blocker toxicity
b) Hypomagnesemia
c) Hypocalcemia
d) Hyperkalemia
b) Hypomagnesemia
