We are the subreddit home of all EKG professionals, amateurs, and anyone else interested in interpreting EKGs.

NOTE: This subreddit cannot give out medical advice or diagnose based off an internet image.

The best way to learn an EKG is to get the basics in the field under the mentorship of a doctor, nurse, or paramedic and then read up on the particulars.

Ekg questions , paramedic interpretation

I had a 65 female c/c inner thigh groin pain 2 hours before her normal dialysis appointment. She went to dialysis (she goes every other day). Even though this call was for pain, I asked if it was her normal to have a lower heart rate than normal after dialysis.

Rate: 53bpm Looks sinus to me but curious about what looked to be taller T waves in leads v4-v6.

My knowledge of unexplained bradycardias with widened qrs and tented T waves (in all leads) are likely hyperkalemia, unsure if that’s accurate to my standards .

What do you think?

SVT with bundle or VTACH?

85 male no pain or acs symptoms. Just felt like heart going to fast. Stable.

Fire medic wanted to stemi activate after ready consider acute infarct. Bundle due to morphology of v1 r wave?

Thoughts?

J Wave?

Does this EKG contain a J wave in V3-6? If not other help would be appreciated! Haven’t been able to find the problem on this EKG for my case study and that’s the only thing I can see.

All of the education appreciated! I’m in my 3rd week of my EMT course!

Medscape ECG Challenge

Found this on Medscape and was wrong like 52% of people:

"A 62-year-old man with a history of dilated cardiomyopathy and a left ventricular ejection fraction (LVEF) of 30% presents to the emergency department with complaints of shortness of breath and weight gain.

His physical examination demonstrates bilateral peripheral edema in the knees. Lung examination demonstrates bibasilar rales. He begins intravenous furosemide and is admitted to the hospital for additional therapy. A routine ECG is obtained."

What does the ECG show?

Options given:

  1. SR w/ LBBB
  2. SR w/ Intraventricular Conduction Delay
  3. Ventricular Rhythm
  4. SR w/ RBBB
  5. Normal ECG

Why is this not a LBBB? I might settle for ventricular paced rhythm if the patient had a PM. No info on that.

The argumentation is that in LBBB there shouldn't be septal forces in play and therefore there shouldn't be q waves in V4 - V6 and no r waves in V1 and V2. I disagree. Shouldn't there be initial RV activation that would present as such?

What the hell am I missing?

This patient with 6-7eps of loose stools, got referred to my hospital by a cardiologist saying Requires management at a higher centre. Am I missing something, or is that guy a hoax?

Artifact, flutter or other?

69 yom for respiratory distress. BP 80/40. Recently got off a international flight after a 4 day hospital stay. The PT ended up having a saddle PE. I tried to see if I could get another tracing in case it was just artifact from the diaphoresis but got the same thing after drying the PT off. Thoughts?

Frog ECG

Hey ya'll, I am pretty darn new to reading ECGs! We had to do a lab in one of my classes where we took the ECG of this bullfrog under the stimulation of a few different drugs. For my data analysis' sake, would anyone tell me if I have this labeled right? Is a frog ECG going to have some different characteristics as compared to a humans?

EDIT: THE FROG IS DEAD, I PROMISE. It was killed just before this experiment. And no, I did not enjoy this at all.

Set up!

Paramedic disagreement

This patient had a lot going on. 70 y/o m with hx of NIDDM, CKD stage 3 not on dialysis, and hypertension. Patient is at a psychiatric hospital for dementia and schizoaffective disorder. Patient ran into a door and hit his head. When we got there he was unresponsive, pale, cold. CBG of 70, BP 49/23, pin point pupils equal and not reactive, adequate respiratory rate. I think he is having a lateral MI, other medic thinks it’s hyper k. I see elevation in I, avL, v2 and v3. The t waves are asymmetrical which makes me think this is more likely MI than hyper k, but could be both?

I'm not sure if I'm over-reading this or missing something obvious

This was a practice question and I can't really seem to understand why V1 looks the way it does. I initially think of BBB but V6 seems unremarkable to me. What jumps out to me is elevation in V1-2 and I think R-Axis deviation. Am I reading this right or is there something I am missing?
