Assessing electrocardiogram changes after ischemic stroke with artificial intelligence
by Ziqiang Zeng, Qixuan Wang, Yingjing Yu, Yichu Zhang, Qi Chen, Weiming Lou, Yuting Wang, Lingyu Yan, Zujue Cheng, Lijun Xu, Yingping Yi, Guangqin Fan, Libin Deng ObjectiveIschemic stroke (IS) with subsequent cerebrocardiac syndrome (CCS) has a poor prognosis. We aimed to investigate electrocardiogram (ECG) changes after IS with artificial intelligence (AI). MethodsWe collected ECGs from a healthy population and patients with IS, and then analyzed participant demographics and ECG parameters to identify abnormal features in post-IS ECGs. Next, we trained the convolutional neural network (CNN), random forest (RF) and suppor...

Multi-modal fusion model for predicting adverse cardiovascular outcome post percutaneous coronary intervention
Conclusion. To the best of our knowledge, this is the first study that developed a deep learning model with joint fusion architecture for the prediction of post-PCI prognosis and outperformed machine learning models developed using traditional single-source features (clinical variables or E CG features). Adding ECG data with clinical variables did not improve prediction of all-cause mortality as may be expected, but the improved performance of related cardiac outcomes shows that the fusion of ECG generates additional value.

Observational study on passive leg raising and the autonomic nervous system
This study aims to clarify these concomitant changes during PLR. A convenience number of healthy volunteers (N = 11) were recruited by advertisement in university departments. The subjects were exposed to the established PLR sequence and the heart rate (HR), mean arterial pressure (MAP), SV, and CO were sampled at 1 Hz, while electrocardiogram was recorded at 1000 Hz. Relative powers reflecting autonom ic nervous system activity were assessed from spectral analysis of HRV. In response to PLR, SV increased (12.4% ± 8.7%,p <  0.0026), while HR (−7.6% ± 4.7%,p <  0.0009) and MAP (−7.6% ± ...

Predicting atrial fibrillation after ischemic stroke: clinical, genetics and electrocardiogram modelling
Introduction: Detection of atrial fibrillation (AF) is challenging in patients after ischemic stroke due to its paroxysmal nature. We aim to determine the utility of a combined clinical, electrocardiographic and genetic variables model to predict AF in a post-stroke population. Materials and Methods: We performed a cohort study at a single comprehensive stroke centre from 09/11/2009 to 31/10/2017. All patients recruited were diagnosed with acute ischemic stroke or transient ischemic attacks. Electrocardiographic variables including p-wave terminal force (PWTF), corrected QT interval (QTc) and genetic variables including ...

Paroxysmal AV Block
A 69 year old woman with a history of congestive heart failure and stroke presented to the emergency room with sudden onset lightheadedness leading to a fall at the grocery store and sustaining head trauma. On physical examination, she was alert and in mild distress. Her HR was 72 beats per minute and blood pressure was 196/70. A 12 lead electrocardiogram (ECG) showed normal sinus rhythm, first degree atrioventricular (AV) block and right bundle branch block. She was admitted for management of subdural hematoma which was noted on CT scan.

Sensors, Vol. 22, Pages 9480: An Ensemble Learning Method for Emotion Charting Using Multimodal Physiological Signals
ammad Usman Akram Emotion charting using multimodal signals has gained great demand for stroke-affected patients, for psychiatrists while examining patients, and for neuromarketing applications. Multimodal signals for emotion charting include electrocardiogram (ECG) signals, electroencephalogram (EEG) signals, and galvanic skin response (GSR) signals. EEG, ECG, and GSR are also known as physiological signals, which can be used for identification of human emotions. Due to the unbiased nature of physiological signals, this field has become a great motivation in recent research as physiological signals are generated auton...

P ‐wave durations from automated electrocardiogram analysis to predict atrial fibrillation and mortality in heart failure
ConclusionsExtreme values of maximum P-wave durations ( ≤90 ms and ≥141 ms) were significant predictors of new-onset AF, cardiovascular mortality, and all-cause mortality.

Sensors, Vol. 22, Pages 9347: Efficient Lightweight Multimodel Deep Fusion Based on ECG for Arrhythmia Classification
Elgendy An arrhythmia happens when the electrical signals that organize the heartbeat do not work accurately. Most cases of arrhythmias may increase the risk of stroke or cardiac arrest. As a result, early detection of arrhythmia reduces fatality rates. This research aims to provide a lightweight multimodel based on convolutional neural networks (CNNs) that can transfer knowledge from many lightweight deep learning models and decant it into one model to aid in the diagnosis of arrhythmia by using electrocardiogram (ECG) signals. Thus, we gained a multimodel able to classify arrhythmia from ECG signals. Our system&a...

Safety of different types of loaded breathing in adult Fontan patients
Conclusion: Short RMT activities are safe in asymptomatic adult Fontan patients. Physiological responses depend on type of RMT and do not reach maximum CPET levels. First trainings should be monitored specifically when applying high positive intrathoracic pressures.

A 28-year-old male with spontaneous coronary artery dissection complicated by apical thrombus and acute ischemic stroke: An interesting case
Radiol Case Rep. 2022 Nov 2;18(1):246-249. doi: 10.1016/j.radcr.2022.10.001. eCollection 2023 Jan.ABSTRACTSpontaneous coronary artery dissection is described as the intramural bleeding that separates the layers of an epicardial coronary artery wall, either with or without an intimal tear. Atherosclerosis, iatrogenic damage, or trauma are not linked to this syndrome. Here we present a 28-year-old male with 1 month history stroke but no any chronic disease as well family history of heart disease who presented with 2 days' duration of typical cardiac chest pain. Based on an emergency electrocardiogram that showed biphasic T-w...
