See these 2 articles Association between pre-hospital chest pain severity and myocardial injury in ST elevation myocardial infarction: A post-hoc analysis of the AVOID study Author links open overlay panel [link] 1 Background We sought to determine if an association exists between prehospital chest pain severity and markers of myocardial injury.
Persistent cardiac arrhythmias are readily amenable to detection by performing a standard electrocardiogram (ECG), but detection of transient (paroxysmal) arrhythmias has long been a significant cause of frustration to both doctors and patients. This article aims to provide a helpful overview for patients and doctors advising them.
Symptom-driven electrocardiogram (ECG) recording plays a significant role in the detection of post-ablation atrial fibrillation recurrence (AFR). The authors of an article published in Cardiovascular Innovations and Applications deployed a deep learning (DL)-based handheld device to facilitate symptom-driven monitoring.
A novel artificial intelligence (AI) model applied to a 12-lead electrocardiogram (ECG) image was able to identify individuals at elevated risk of heart failure (HF) across multinational cohorts without HF at baseline, according to a study published Jan. 13 in European Heart Journal.
Ryan Burch, RN, was the nurse caring for the patient, later sent me the same ECG, stating the following: "This ECG had people stumped and concerned but I read an article in www.ecgmedicaltraining.com (see below) about an artifact a few weeks prior which I thought looked similar and the suggestion was that a lead had been placed over an artery.
13 that Philips is correcting the Monitoring Service Application used with Mobile Cardiac Telemetry Monitoring as some electrocardiogram (ECG) events received by the application between July 2022 to July 2024 were not properly routed, which may have led to missing information or notifications.
The purpose of this article is to discuss possible ways of improving the quality of ECG signals in order to obtain more reliable results. Contractions of the heart muscle are caused by electrical impulses, which, when recorded on a graph, form an electrocardiogram. Why does the quality of the ECG signal matter?
Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review. For all cases, see the supplement from the online version of the article. This was just published in print in this month's Academic Emergency Medicine: McLaren, Meyers, Smith and Chartier.
What is the impact of a patient-initiated remote monitoring service including 12-lead electrocardiogram (ECG), vital sign data, and algorithmically supported clinical review on the risk of readmission following acute coronary syndrome (ACS)?
Similar promise is evident in the analysis of electrocardiograms, creating a new layer of interpretation. There is growing evidence that AI algorithms can match humans at echocardiography analysis, while also being able to extract subtle differences that the human eye cannot detect.
Comment A recently published article (1) found that a computer-interpreted “normal” ECG has a 99% NPV (95% CI: 97-99) for a clinically significant finding. According to 2 recent articles (2, 3), the computer misses one third of STEMI, but misses many more subtle MI that do not meet STEMI criteria. This one was not even so subtle!!!
Arterial pulse tapping artifact [link] This online article references the article below by Emre Aslanger, a great guy who occasionally corresponds with me about ECGs. Electromechanical association: a subtle electrocardiogram artifact. Figure-3: Page 475 from the Rowlands and Moore article that I reference above.
Cardiovascular consultation had been requested for all of the patients based on their primary clinical examination, vital signs, and electrocardiogram (ECG). In this cross-sectional study, 690 COVID-19 patients were included.
Here is an article I wrote: Updates on the ECG in ACS. Updates on the Electrocardiogram in Acute Coronary Syndromes. Electrocardiogram patterns in acute left main coronary artery occlusion. STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? If you want to understand aVR, read this.]
The electrocardiogram (ECG) revealed T-wave inversions on precordial leads. A 59-year-old woman presented to the emergency room with sudden onset of retrosternal thoracic pain following emotional stress. Her blood analyses demonstrated elevation of myocardial necrosis markers (peak of troponin I of 3.4
Many systems now refrain from showing computer "normal" ECGs to the busy emergency physicians at triage because of very poorly conceived articles that say that if the computer algorithm says "normal," the emergency physician should not be bothered. It is clearly missed by the conventional algorithm.
Here is the classic article on continuous 12-lead monitoring (in full text) showing that the ECG is a much more reliable indicator of re-occlusion than are symptoms. Here is another classic article. It is well documented with continuous 12-lead monitoring that acute re-occlusion is frequently asymptomatic. Patel DJ, et al.
Safety evaluation results showed no significant changes in the QRS wave or PR and QT intervals in rat lead II electrocardiograms. Safety evaluation results showed no significant changes in the QRS wave or PR and QT intervals in rat lead II electrocardiograms.
See the 5 articles below. Crochetage sign You can see many more images of the Crochetage sign here. N OTE : The term, “crochetage” in French is the noun ( = the act of crocheting ) — but this word has also been translated into English as meaning, “lock-picking” ( because lock-pickers often use a similar array of tools in their trade ).
The demographic, clinical, and electrocardiogram features of the patients in each group were compared. For symptomatic patients, the correlation between palpitations and PVC was further evaluated based on the temporal consistency of symptom onset and PVC occurrence. Results Of the 214 patients enrolled, 124(57.9%) experienced palpitations.

Traditional tools like stethoscopes, blood pressure gauges, and electrocardiograms (ECG) are fundamental for standard diagnostic practices.
This was just published in JAMA Internal Medicine: The de Winter Electrocardiogram Pattern Evolving From Hyperacute T Waves It reminded me that many believe, due to the assertions in the original de Winter's article, that de Winter's waves are stable.
Follow-up contained regular visits at our outpatient clinic at 1, 3, 6, and 12 months including 7-day Holter electrocardiograms. In addition to pulmonary vein isolation (PVI), ablation of DISPERS was performed aiming at homogenizing, dissecting, isolating, or connecting DISPERS areas to nonconducting anatomical structures. to 202.2 ± 21.6 ms
The ECG, as it turns out, is the best predictor , better the TMP grade because TMP measures microvascular patency, and the ECG measures cellular viability ( see this full text article and this abstract ). Clinical value of 12-lead electrocardiogram after successful reperfusion therapy for acute myocardial infarction.
