We included all patients aged 18 years or older with at least one digital, normal sinus rhythm, standard 10-second, 12-lead ECG acquired in the supine position at the Mayo Clinic ECG laboratory between Dec 31, 1993 (...) An artificial intelligence-enabled ECG algorithm for the identification of patients with atrial fibrillation during sinus rhythm: a retrospective analysis of outcome prediction. Atrial fibrillation is frequently asymptomatic and thus underdetected but is associated with stroke, heart failure, and death. Existing screening methods require prolonged monitoring and are limited by cost and low yield. We aimed to develop a rapid, inexpensive, point-of-care means of identifying patients with atrial

Predicting sudden cardiac death in a general population using an electrocardiographic risk score We investigated whether combining several ECG abnormalities would identify general population subjects with a high sudden cardiac death (SCD) risk.In a sample of 6830 participants (mean age 51.2±13.9 years; 45.5% male) in the Mini-Finland Health Survey, a general population cohort representative of the Finnish adults aged ≥30 years conducted in 1978-1980, we examined their ECGs, following subjects (...) for 24.3±10.4 years. We analysed the association between individual ECG abnormalities and 10-year SCD risk and developed a risk score using five ECG abnormalities independently associated with SCD risk: heart rate >80 beats per minute, PR duration >220 ms, QRS duration >110 ms, left ventricular hypertrophy and T-wave inversion. We validated the score using an external general population cohort of 10 617 subjects (mean age 44.0±8.5 years; 52.7% male).No ECG abnormalities were present in 4563 subjects

Peguero Electrocardiographic Left Ventricular Hypertrophy Criteria and Risk of Mortality Background: Peguero electrocardiographic left ventricular hypertrophy (ECG-LVH) criteria are newly developed criteria that have shown better diagnostic performance than the traditional Cornell-voltage and Sokolow-Lyon criteria. However, prediction of poor outcomes rather than detection of increased left ventricular mass is becoming the primary use for ECG-LVH criteria which requires investigating any new (...) ECG-LVH criteria in terms of prediction. Aims: To examine the prognostic significance of the newly developed Peguero ECG-LVH criteria. Methods: We compared the prognostic significance of Peguero ECG-LVH with Cornell-voltage and Sokolow-Lyon ECG-LVH criteria in 7,825 participants (age 59.8 ± 13.4 years; 52.7% women) from the third National Health and Nutrition Examination Survey who were free of major intraventricular conduction defects. ECG-LVH criteria were derived from digital ECG tracings

Syncope and ST Elevation on the Prehospital ECG Dr. Smith's ECG Blog: Syncope and ST Elevation on the Prehospital ECG Saturday, June 20, 2020 A 75 yo with h/o CAD, CABG, and HFrEF presented after a syncopal episode. There was no prodrome and no associated symptoms such as SOB or CP. The medics recorded an ECG: There is STE in V1-V3 and aVL, with reciprocal ST depression in II, III, aVF. The medics were worried about STEMI, as it meets STEMI criteria. What do you think? On arrival, BP was 150/80 (...) , with a pulse of 80. An ECG was recorded: Now you can see what the medics could not: The QRS is enormous. There is LVH. The ST Elevation is due entirely to LVH. The QRS duration is 118 ms , so by definition it is not Left Bundle Branch Block (which must be 120 ms at a minimum and is usually longer) Thus, LVH on the ECG does not always correlate with anatomic LVH. Nevertheless, high voltage does correlate with abnormal ST segments The S-wave in V2 is 50 mm; STE is 2.5. Ratio = 0.05, which is normal. LVH

Cardiac Arrest. What does the ECG show? Also see the bizarre Bigeminy. Dr. Smith's ECG Blog: Cardiac Arrest. What does the ECG show? Also see the bizarre Bigeminy. Wednesday, April 29, 2020 A 60-something woman presented after a witnessed cardiac arrest. CPR was started immediately. EMS arrived and found her in a wide complex PEA rhythm. She was given 3 mg IV epinephrine and multiple rounds of ACLS over approximately 20 minutes. Her husband stated that she had not been feeling well (...) in the past 2 weeks and c/o dizziness as well as diarrhea. She was never defibrillated. I was texted this ECG in real time, but it turns out to actually be the 2nd one recorded in the ED. What do you think? This is what I wrote: This looks like pseudoSTEMI to me. What appears to be ST elevation seems to be a wide QRS. I am only looking on my phone though. Indeed, if you find the end of the QRS, which is easy to see in V1, then draw a line down to lead II across the bottom, then you can find the end

Looking through a stack of ECGs for a troponin study..... Dr. Smith's ECG Blog: Looking through a stack of ECGs for a troponin study Thursday, May 7, 2020 And I came across this one while reading EKGs for a high sensitivity troponin study: what do you think? Normally, if one sees STE in aVL with reciprocal STD in III, one would say "Acute OMI". But I instantly knew it was not. I immediately recognized it as normal, and classified it for the study (blinded) as "normal with normal ST Elevation (...) and "normal ST depression." More on this ECG: All I know when I see the ECG for this study is that the patient has had at least 2 troponins drawn. I don't know whether it is for chest pain, weakness, whatever. I don't know for certain why my (our) mind immediately knows that it is normal. I believe it is partly the flat STE, lots of upward concavity in the STE so that T-wave does not look hyperacute (hyperacute T-waves are "fat" because there is less upward concavity). But there is terminal QRS distortion

56. Electrocardiogram (ECG) for the Prediction of Incident Atrial Fibrillation: An Overview Full Text available with Trip Pro

Electrocardiogram (ECG) for the Prediction of Incident Atrial Fibrillation: An Overview Electrocardiograms (ECGs) have been employed to medically evaluate participants in population-based studies, and ECG-derived predictors have been reported for incident atrial fibrillation (AF). Here, we reviewed the status of ECG in predicting new-onset AF. We surveyed population-based studies and revealed ECG variables to be risk factors for incident AF. When available, the predictive values of each ECG (...) risk marker were calculated. Both the atrium-related and ventricle-related ECG variables were risk factors for incident AF, with significant hazard risks (HRs) even after multivariate adjustments. The risk factors included P-wave indices (maximum P-wave duration, its dispersion or variation and P-wave morphology) and premature atrial contractions (PACs) or runs. In addition, left ventricular hypertrophy (LVH), ST-T abnormalities, intraventricular conduction delay, QTc interval and premature

59. A PCA/ICA based Fetal ECG Extraction from Mother Abdominal Recordings by Means of a Novel Data-driven Approach to Fetal ECG Quality Assessment Full Text available with Trip Pro

A PCA/ICA based Fetal ECG Extraction from Mother Abdominal Recordings by Means of a Novel Data-driven Approach to Fetal ECG Quality Assessment Fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. By early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant.Here, we extract fetal ECG from maternal abdominal recordings and detect R-peaks in order to recognize fetal heart rate. On the next (...) step, we find a better and more qualified extracted fetal ECG by using a novel approach.In this paper, a PCA/ICA-based algorithm is proposed for extracting fetal ECG, and fetal R-peaks are detected as well. The method validates the quality of extracted ECGs and selects the best candidate fetal ECG to provide the required morphological ECG features such as fetal heart rate and RR interval for more clinical examinations. The method was evaluated using the dataset which was provided by PhysioNet
