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 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 ...

Reviewing the all-in-pod heart health segment
BY ANISH KOKA
The All-in podcast is a fairly popular show that features successful silicon valley investors commenting about everything worth commenting on from politics to health. The group has good chemistry and interesting insights that breaks the mold of the usual tribal politics that controls legacy media analysis of current events.
Last week, the podcast touched on a topic I spend a fair amount of time on: Cardiology.
Brad Gerstner, who is actually a guest host for this particular episode starts off by referencing something called Heartflow to evaluate the heart that has been recommended by one of the o...

Another myocardial wall is sacrificed at the altar of the STEMI/NonSTEMI mass delusion (and Opiate pain relief).
I received the following text message with these 3 EKGs (providers text me ECGs all day every day; most are false positives; many are subtle true positives):" Hi Steve, here are 3 EKGs for you (my colleague ' s case). A 67 yo f developed chest pain this morning. "EKG #1Followed 15 minutes by this #2 EKG:Then the patient received aspirin andDilaudid (hydromorphone, same effect as morphine) and the pain went away and there was this 3rd ECG:Smith comment: hydromorphone will make any pain go away (or improve) without any improvement in the underlying pathology. Do NOT give it unless you are committed to t...

A man in his early 40s with chest pain a " normal ECG " by computer algorithm. Should we avoid interrupting a physician to interpret his ECG?
This study looked at less than 1000 cases, which is not nearly enough (see below for analysis) and they used cardiologists as the gold standard (a very poor gold standard), NOT presence or absence of Occlusion MI (which we have done in all of our ECG studies, and must be ascertained by 1) TIMI 0/2 flow on angiogram or 2) culprit + TIMI 3 flow and very high troponin. So this study is worthless and must be ignored. I have here 38 cases of " Computer Normal " ECGs which were critically abnormal and the vast majority are missed acute coronary occlusions (Missed Acute OMI) and most were recognized ...

Can Radial Artery be Used as Conduit for CABG After Transradial Coronary Angiography?
Radial artery is being increasingly used as a conduit for coronary artery bypass grafting in multi-vessel coronary artery disease as it provides superior long term patency rates compared to saphenous vein grafts [1]. Radial artery is also increasingly being used as access point for coronary angiography and percutaneous coronary interventions. Concerns have been raised regarding the use of radial artery as conduit after transradial procedures as there is likelihood of vascular trauma during the procedures.
Some authors even mention that prior transradial catheterization is a contraindication for the use of radial artery fo...

Off and on chest pain for 24 hours in a 50s year old man
Submitted by Ali Khan MD and James Mantas MD, MS, written by Pendell MeyersA man in his 50s with history of diabetes, hypertension, and tobacco use presented to the ED with 24 hours of worsening left sided chest pain radiating to the back, characterized as squeezing and pinching, associated with shortness of breath. His pain was initially mild, then became severely worse several hours prior to presentation, but then eased off again and was minimal on arrival. There was no associated diaphoresis, nausea, vomiting, arm pain, jaw pain, syncope, lightheadedness or other acute symptoms.Initial vitals: Temp 36.7 C, BP 161/79, RR...

70-year-old with acute chest pain, STEMI negative: just an old infarct?
Submitted by Dr. Dennis Cho (@DennisCho),
written by Jesse McLaren A 70-year-old with no cardiac history
presented with 2 hours of chest pain radiating to the neck, associated with
shortness of breath. What do you think?There ’s normal sinus rhythm, first-degree
AV block, normal axis and voltages. R wave progression is abnormal: there are Q
waves in aVL/V2-3 and loss of R wave in V2. This is accompanied by minimal ST
elevation in aVL/V1-V2 and more pronounced inferior reciprocal ST depression, and minimal ST depression V5-6.
This is diagnostic of OMI, either proximal LAD or first diagonal. Q wave, old
infarct?B...

Dueling OMI: does this 30 year old with chest pain have any signs of occlusion or reperfusion?
Written by Jesse McLaren, with edits from Smith A 30 year old with a history of diabetes presented with two days of intermittent chest pain and diaphoresis, which recurred two hours prior to presentation. Below is ECG #1 at triage. Are there any signs of occlusion or reperfusion?There ’s normal sinus rhythm, normal conduction, normal axis, normal R wave progression and normal voltages. There’s mild inferior ST elevation in III that doesn’t meet STEMI criteria, but it’s associated with ST depression in aVL and V2 that makes itdiagnostic of infero-posterior Occlusion MI (from either RCA or circumflex) – accomp...

Chest pain, and Cardiology didn ' t take the hint from the ICD
Submitted and written by Megan Lieb, DO with edits by Bracey, Smith, Meyers, and GrauerA 50-ish year old man with ICD presented to the emergency department with substernal chest pain for 3 hours prior to arrival. The screening physician ordered an EKG and noted his ashen appearance and moderate distress. Triage EKG:What do you think?Triage physician interpretation: -sinus bradycardia-lateral ST depressionsWhile there are lateral ST depressions (V5, V6) the deepest ST depressions are in V4. Additionally, lead V3 has ST depressions, which are always abnormal (recall that lead V3 will haveST elevation under nor...

A teenager with chest pain, a troponin below the limit of detection, and " benign early repolarization "
Sent by anonymous, written by Pendell MeyersA male in his teens presented with complaints of chest discomfort and dyspnea beginning while exercising but without obvious injury. He immediately stopped exercising and symptoms started to improve. Later that evening he felt recurrent central chest discomfort, shortness of breath, and vomited. Symptoms have been constant since this second episode, and are still present on arrival, which seems to have been less than 1 to 2 hours from onset of symptoms. No similar symptoms in the past. No prior exertional complaints of chest pain, dizziness, lightheadedness, or undue shortness of...

A woman in her 50s with acute chest pain
Submitted and written by Anonymous, edits by Meyers and SmithA 50s-year-old patient with no known cardiac history presented at 0045 with three hours of unrelenting central chest pain. The pain was heavy, radiated to her jaw with an associated headache.Triage VS: 135/65 mmHg, 95 bpm, 94% on room air, 16/min, 98.6 FTriage ECG:ECG Interpretation:Sinus rhythm with normal QRS. There is slight STE in V1, V2, and aVR, with STD in V3-V6, I, aVL, and II. There are T waves in lead III which are suspicious for hyperacute T waves, with reciprocal negative large T wave inversions in aVL. I do not think this ECG is by itself diagnostico...

65 year old with syncope and a ' normal ' ECG: discharge home?
A 65 year old with diabetes presented with a syncopal episode while sitting, associated with weakness but no chest pain or shortness of breath. Vital signs were normal and first ECG was labeled as normal by the computer and confirmed by the treating emergency physician and cardiology over-read. What do you think? There ’s normal sinus rhythm, normal conduction, normal axis, normal R wave progression, and normal voltages with J waves from early repolarization. There ' s inferior down-up ST segments and hyperacute T waves, with reciprocal up-down T wave in aVL. I sent this " normal " ECG without any informa...

Upon arrival to the emergency department, a senior emergency physician looked at the ECG and said " Nothing too exciting. "
This article fails to specify whether it was troponin I or T, but I contacted the institution and they used exclusively troponin I during that time period.Reference on Troponins: Xenogiannis I, Vemmou E, Nikolakopoulos I, et al.

90 year old with acute chest and epigastric pain, and diffuse ST depression with reciprocal STE in aVR: activate the cath lab?
ConclusionsSTE-aVR with multilead ST depression was associated with acutely thrombotic coronary occlusion in only 10% of patients. Routine STEMI activation in STE-aVR for emergent revascularization is not warranted, although urgent, rather than emergent, catheterization appears to be important.===================================MY Comment, by KEN GRAUER, MD (11/5/2022):===================================Our thanks to Drs. El-Baba and McLaren — for their presentation in today’s post about an important topic worthy of our periodic reminders. We’ve presented many variations on this theme on...
