How Could Digital Technology Make An Impact On Primary Care?
I truly hope that very soon I do not have to make an appointment at the GP when I suspect signs of a disease, but my GP will send me a message that she spotted something irregular in my latest test results and my digital health data, so I’d better visit. Let me show you in detail how primary care should be carried out in the future! Digital health should become an organic part of primary care in the future I live a fairly healthy life. I use data to improve my lifestyle and to make better decisions by optimising my sleep pattern, my physical, my cognitive or my emotional abilities; and I had several genetic tests....

50 year-old in remote rural community with chest pain and ‘normal’ ECG
Submitted by anonymous, edited by Jesse McLarenThe first person " I " and " me " is this anonymous sender. A 50 year old presented to the emergency department of a remote rural community (where the nearest cath lab is a plane ride away) with one hour of mild chest pain radiating to the back and jaw, and an ECG labeled ‘normal’ by the computer interpretation. What do you think, and how would you manage the patient?There ’s normal sinus rhythm, normal conduction, normal axis, normal R wave progression and normal voltages. There’s clear T wave inversion in III/aVF, which is reciprocal to subtle ST elevation and h...

A middle-aged man with acute chest pain.
A 50-something male had onset of chest pain 1 hour prior to ED arrival.  It is constant, 9/10, left-sided CP that radiates into left arm and jaw. Endorses some associated SOB, but denies back pain, fever, cough, chills, leg swelling, or other new symptoms. Has never had this before. Takes metoprolol for HTN. Here is the triage ECG:What do you think?This was not identified as OMI by either the conventional algorithm nor the triage faculty physician.Smith: I think leads V3 and V4 are highly concerning, and all but diagnostic, for acute LAD occlusion.  I would activate the cath lab, or at least look f...

75 year old dialysis patient with nausea, vomiting and lightheadedness
Written by Jesse McLaren A 75 year-old patient with diabetes and end stage renal disease was sent to the ED after dialysis for three days of nausea, vomiting, loose stool, lightheadedness and fatigue. RR18 sat 99% HR 90 BP 90/60, afebrile. Below is the 15 lead ECG. What do you think? There ’s normal sinus rhythm, normal conduction, normal axis, normal R wave progression and normal voltages. There’s subtle inferior ST elevation with straightening of the ST segment, reciprocal ST depression and T wave inversion in aVL, and ST depression in V2. This is diagnostic of infero-posterior OMI, but it is falsely n...

Chest pain and T wave inversion, NSTEMI?
Case submitted and written by Dr. Mazen El-Baba and Dr. Emily Austin, with edits from Jesse McLarenA 50 year-old patient presented to the Emergency Department with sudden onset chest pain that began 14-hours ago. The nurse alerted the MD because the patient was still symptomatic, diaphoretic and “looking unwell”. What do you think?      ECG interpretation: sinus rhythm, normal conduction (PR, QRS, and QTc), normal axis, delayed R-wave progression, and normal voltages. There ’s primary TWI inferiorly (aVF and III) and V6, with reciprocal tall T-wave in lead I/aVL, and a Q wave in III. The...

OMI Pocket Guide
  📕OMI Pocket Guide TheOMI Pocket Guide (https://omiguide.org) is a user-friendly online resource designed to help healthcare professionals learn how to recognize subtle signs of acute coronary occlusion on the ECG which represent occlusion myocardial infarctions (OMI). Learning to recognize OMIs is an important clinical skill because it helps identify the subpopulation of " NSTEMIs " who are likely to be found with total thrombotic occlusion at the time of cardiac catherization.Although there are more criteria to consider when looking for OMIs compared to STEMIs, anyone can learn them, and this guid...

A man in his 70s with weakness and syncope
DiscussionBrugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. Patients that develop a Type 1 pattern without any precipitating or provoking factors have a risk of SCD of 0.5-0.8% per year. In patients that only have this pattern induced by a sodium channel blocking agent have a lower rate of SCD (0 - 0.35% per year)[1]. Drugs that have been associated with Brugada ECG patterns include tricyclic antidepressants, anesthetics, cocaine, methadone, antihistamines, electrolyte derangements, and even tramadol. [2]. Our patient had a Brugada Type ...

I was reading ECGs on the system when I came across this one, called " normal " by the conventional computer algorithm
I come in early for every shift to read the ECGs on the system that have not yet been " confirmed " .  I came across this one:The computer calls is: " SINUS RHYTHM. NORMAL ECG "What do you think? Be VERY careful when the computer calls the ECG " Normal " .  I saw the inferior ST depression (which is reciprocal to subtle STE in aVL) and the subtle ST depression in precordial leads and thought:" If this patient came in with chest pain, then it is an acute OMI. "So I looked on the computer.  Turns out that it was a 50-something patient with no previous cardiac history who had called 911 for chest pain...

63 year old with " good story for ACS " but negative troponins.....
 This was texted to me from a former resident, while working at a small rural hospital, with the statement:" I can ’t convince myself of anything here, but he’s a 63-year-old guy with prior stents and a good story for ACS. "  (Chest pain or discomfort)What do you think?Here was my response:" Suspicious for inferior posterior OMI.  Get serial ECGs "He then sent a previous from 4 years prior:" This is totally normal, which confirms that the first EKG does indeed represent OMI "Then the patient ' s chest pain resolved and he recorded another:The ST depression in aVL is gone and the T-waves are less hyperacu...

Wide complex tachycardia and hypotension in a 50-something with h/o cardiomyopathy -- what is it?
A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension.Bedside echo showed " mildly reduced " LV EF.Here is the ED ECG:What do you think?Analysis: there is a wide complex tachycardia. It is regular.  There are no P-waves.  The morphology is of RBBB and LAFB.  The initial part of the QRS is very fast, suggesting that it starts in conducting fibers and not in myocardium.  Thus, it is probably SVT with aberrancy (RBBB + LAFB) or it is posterior fascicular VT (which starts in the pos...

A man with chest pain off and on for two days, and " No STEMI " at triage.
 Written by Kaley El-Arab MD, edits by Pendell Meyers and Stephen SmithA 61-year-old male with hypertension and hyperlipidemia presented to the emergency department for chest tightness radiating to the back of his neck that has been intermittent for the past day or two. Here is his triage ECG which was obtained at 20:34 during active pain.What do you think?This ECG was read as “No STEMI” with no prior available for comparison. It is true this ECG does not meet STEMI criteria (there is 1.0 mm STE in III, and possibly 0.5 mm in aVF), but there is clear evidence of OMI findings on this ECG. Leads II, III, and aVF hav...

Two ECGs texted to me in the same hour. What would you recommend?
Written by Pendell MeyersBoth of these cases were sent to me with no information other than adults with acute chest pain. What would be your response?Case 1:Case 2:What if I told you that Case 1 has an abnormal initial troponin, and Case 2 has a normal initial troponin? Case 1An elderly male presented with chest pain. His vitals were within normal limits except some mild hypertension. Here was his triage ECG:What do you think?I texted back: " I just see LVH with no signs of OMI " .I sent this ECG to the Queen of Hearts (PMcardio OMI), and here is the verdict:You can subscribe for news and early access (via partic...

A young man with another episode of tachycardia. What is it? And why give adenosine in sinus rhythm?
Written by Bobby Nicholson MD and Pendell MeyersA man in his 30s presented to the ED for evaluation of chest pain and palpitations. He described it as a " jackhammering " sensation, associated with palpitations, diaphoresis, and shortness of breath, and he stated it started soon after consuming an " energy drink " (product/contents unknown).He stated these symptoms were the same as a prior episode which required cardioversion. He states that he has a heart condition which he does not know the name of and that he has felt his heart race like this once before and needed to be shocked. He was seen by a cardiologist in fo...

75 year old with 24 hours of chest pain, STEMI negative
Written by Jesse McLaren A 75 year old with a history of CABG called EMS after 24 hours of chest pain. HR 40, BP 135/70, RR16, O2 100%. Here ’s the paramedic ECG (digitized by PMcardio). What do you think? There ’s sinus bradycardia, normal conduction, normal axis, delayed R wave progression, and normal voltages. There are inferior Q waves and lead III has mild concave ST elevation, with subtle reciprocal ST depression in I/aVL. This is diagnostic of inferior OMI, likely from the RCA. The patient has a hi story of CABG so some of these changes could be old, but with ongoing chest pain and bradycardia in a hig...
