Perioperative Risk Factors of Atrial Fibrillation Post CABG Surgeries, a Retrospective Non-Randomized Study
ConclusionThe current study found that low ejection fraction, dilated left atrium, hypertension, smoking, old age, male gender, prolonged bypass time, prolonged cross clamping time, renal impairment, previous myocardial infarction, ungrafted dominant right coronary artery, low temperatures on bypass, early ischemic changes postoperative, hypokalemia, use of adrenaline and nor adrenaline, all of these factors were a significant predictors for development of atrial fibrillation after cardiac surgery.

Impact of left ventricular ejection fraction and preoperative hemoglobin level on perioperative adverse cardiovascular events in noncardiac surgery
AbstractThe prediction of a perioperative adverse cardiovascular event (PACE) is an important clinical issue in the medical management of patients undergoing noncardiac surgery. Although several predictors have been reported, simpler and more practical predictors of PACE have been needed. The aim of this study was to investigate the predictors of PACE in noncardiac surgery. We retrospectively analyzed 723 patients who were scheduled for elective noncardiac surgery and underwent preoperative examinations including 12-lead electrocardiography, transthoracic echocardiography, and blood test. PACE was defined as cardiac death,...

The comparison of Kardia Mobile and Hartmann Veroval 2 in 1 in detecting first diagnosed atrial fibrillation
CONCLUSIONS: Mobile devices can detect AF, but each finding must be verified by a professional. The Kardia application appeared to be more user-friendly than Veroval. Cardiovascular screening using mobile devices is feasible at pharmacies. Hence it might be considered for routine use.PMID:34355779 | DOI:10.5603/CJ.a2021.0083

Sensors, Vol. 21, Pages 5302: Automatic Detection of Short-Term Atrial Fibrillation Segments Based on Frequency Slice Wavelet Transform and Machine Learning Techniques
uang Zhou Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia and is often associated with other cardiovascular and cerebrovascular diseases, such as ischemic heart disease, chronic heart failure, and stroke. Automatic detection of AF by analyzing electrocardiogram (ECG) signals has an important application value. Using the contaminated and actual ECG signals, it is not enough to only analyze the atrial activity of disappeared P wave and appeared F wave in the TQ segment. Moreover, the best analysis method is to combine nonlinear features analyzing ventricular activity based on the detection ...

Prognostic Significance of Fragmented QRS in Patients with Acute Ischemic Stroke
Stroke is a leading cause of mortality and morbidity in developed countries1 and has a strong relationship with cardiovascular system disorders.2 Due to this relationship, the connection between brain and heart has become increasingly important and neurocardiology has emerged as a popular concept over the recent years.3 Electrocardiographic abnormalities and various cardiac arrhythmias occurring especially after stroke support this phenomenon.4 ST segment and/or T-wave abnormalities without myocardial ischemia,5 left axis deviation, QT prolongation,6 QT dispersion,7 atrial fibrillation (AF), sinus tachycardia, ventricular ...

Relationship of electrocardiographic changes and severity of acute cerebral ischemic stroke in old patients: A clinical observational study
This study was aim to provide referential data for this topic. Totally 200 old patients with acute CIS in our hospital from January 2017 to December 2019 were included into this study. According to the ST-T segment changes in ECG, these patients were divided into 3 groups: persistent ischemic group (n = 38), transient ischemic group (n = 106) and non-ischemic group (n = 56). The characteristics and incidence of abnormal ECG and their relationship with disease severity, infarct size and prognosis were respectively analyzed under the severe, moderate and mild type of disease. The ECG changes of patients wer...

Functional Calsequestrin-1 Is Expressed in the Heart and Its Deficiency Is Causally Related to Malignant Hyperthermia-Like Arrhythmia
Conclusions: Casq1 is expressed in the heart, where it regulates SR Ca2+ release and heart rate. Casq1 deficiency independently causes MH/EHS-like ventricular arrhythmia by trigger-induced Casq1 oligomerization and a relief of its inhibitory effect on RyR2-mediated Ca2+ release, thus revealing a new inherited arrhythmia and a novel mechanism for MH/EHS arrhythmogenesis.PMID:34162222 | DOI:10.1161/CIRCULATIONAHA.121.053255

New-onset atrial fibrillation in patients with worsening heart failure and coronary artery disease: an analysis from the COMMANDER-HF trial
ConclusionsA well-calibrated risk-score identified patients at risk of new-onset AF in the COMMANDER-HF trial. Patients who developed AF had a higher risk of subsequent death.Graphic abstractRisk of new-onset atrial fibrillation in patients with HFrEF and coronary artery disease

Sensors, Vol. 21, Pages 3814: Recent Research for Unobtrusive Atrial Fibrillation Detection Methods Based on Cardiac Dynamics Signals: A Survey
Ziyu Zhu Atrial fibrillation (AF) is the most common cardiac arrhythmia. It tends to cause multiple cardiac conditions, such as cerebral artery blockage, stroke, and heart failure. The morbidity and mortality of AF have been progressively increasing over the past few decades, which has raised widespread concern about unobtrusive AF detection in routine life. The up-to-date non-invasive AF detection methods include electrocardiogram (ECG) signals and cardiac dynamics signals, such as the ballistocardiogram (BCG) signal, the seismocardiogram (SCG) signal and the photoplethysmogram (PPG) signal. Cardiac dynamics signals ...
