Holter's ECG monitoring was used to investigate 140 males showing no clinical signs of coronary disease, while having 1 to 5 coronary risk factors (hypodynamia, arterial hypertension, smoking, hypercholesterolemia). Supraventricular rhythm disorders were recorded in 86%, and ventricular ones, in 69%. Transitory ST depression was detected in 15% of the cases, appearing in response to physical (90%) of mental (9%) stress or spontaneously in 1%. Ninety percent of ischemic attacks were asymptomatic. Ischemic ECG changes were nearly twice as frequent in patients with 3 to 5 coronary risk factors, as compared to those with 1 or 2 risk factors. It is therefore suggested that asymptomatic coronary disease can be suspected in some of the patients with coronary risk factors. This suspicion is confirmed by positive bicycle ergometric test in 53% of the individuals with changed Holter's ECG monitoring data. Combined use of Holter's ECG monitoring and bicycle ergometry increases twofold the detectability of electrocardiographic abnormalities.

Accuracy of remote, video-based supraventricular tachycardia detection in patients undergoing elective electrical cardioversion: a prospective cohort.

Unobtrusive pulse rate monitoring by continuous video recording, based on remote photoplethysmography (rPPG), might enable early detection of perioperative arrhythmias in general ward patients. However, the accuracy of an rPPG-based machine learning model to monitor the pulse rate during sinus rhythm and arrhythmias is unknown. We conducted a prospective, observational diagnostic study in a cohort with a high prevalence of arrhythmias (patients undergoing elective electrical cardioversion).

Background: There is still a significant population of patients with embolic stroke of Undetermined Source (ESUS) whose specific attributable cause of the stroke remains unknown.
Objectives: Our research aimed to assess clinical, electrocardiogram, laboratory, and echocardiographic parameters that may predict the propensity of paroxysmal atrial fibrillation (PAF).
Methods: We enrolled seventy-five ESUS patients who were in sinus rhythm at the time of stroke diagnosis to undergo in-hospital 7-day Holter monitoring, testing for Pro-BNP, and a standard echocardiographic examination.
Development of a non-invasive heart rate measurement method for sea turtles with dense keratinous scutes through effective electrode placement.

Article Synopsis
- Measuring the heart rate of sea turtles helps us understand their physiological adaptations, particularly focusing on the non-invasive ECG methods developed for loggerhead turtles.
- The study explored alternative electrode placements on the plastron of green sea turtles, finding successful ECG readings when the negative electrode was positioned near the neck.
- Results showed that resting heart rates averaged about 8.6 beats per minute, aligning with previous studies, and highlight the need for careful individual selection to improve measurement reliability.
Beaware of Intracardiac Potentials Induced by Intravascular Lithotripsy.
Catheter Cardiovasc Interv
January 2025
Department of Cardiology, Ageo Central General Hospital, Saitama, Japan.
Background: Intravascular lithotripsy (IVL), that generates shockwaves through spark gap discharge between emitters, has been increasingly used to treat severely calcified coronary artery lesions. However, there is a question as to whether IVL has no electrical effects on endocardial tissues or cardiac implantable devices (CIEDs).
Aims: The aim of this study was to investigate the effects of IVL-induced intracardiac potentials on cardiac electrophysiology and CIEDs.
Multimodal Pain Recognition in Postoperative Patients: Machine Learning Approach.
JMIR Form Res
January 2025
Department of Computer Science, University of California, Irvine, Irvine, CA, United States.
Background: Acute pain management is critical in postoperative care, especially in vulnerable patient populations that may be unable to self-report pain levels effectively. Current methods of pain assessment often rely on subjective patient reports or behavioral pain observation tools, which can lead to inconsistencies in pain management. Multimodal pain assessment, integrating physiological and behavioral data, presents an opportunity to create more objective and accurate pain measurement systems.
