Effects of prolonged working hours on heart rate variability in internal medicine physicians.

Publication Type: Academic Journal

Source(s): Scientific reports [Sci Rep] 2022 Nov 03; Vol. 12 (1), pp. 18563. Date of Electronic Publication: 2022 Nov 03.

Abstract: Prior studies have utilized heart rate variability (HRV) as the assessment tools for psychological and physiological stress during 24-h shift. However, data regarding effects of prolonged working hours > 24 h on HRV are limited. We aimed to compare bet...

Development and Optimization of Silicon-Dioxide-Coated Capacitive Electrode for Ambulatory ECG Measurement System.

Publication Type: Academic Journal

Source(s): Sensors (Basel, Switzerland) [Sensors (Basel)] 2022 Nov 01; Vol. 22 (21). Date of Electronic Publication: 2022 Nov 01.

Authors:

Abstract: This paper presents a silicon-dioxide-coated capacitive electrode system for an ambulatory electrocardiogram (ECG). The electrode was coated with a nano-leveled (287 nm) silicon dioxide layer which has a very high resistance of over 200 MΩ. Due to this...

The next heartbeat: Creating dynamic and histographic Poincaré plots for the assessment of cardiac rhythms.

Publication Type: Academic Journal

Source(s): Journal of veterinary cardiology : the official journal of the European Society of Veterinary Cardiology [J Vet Cardiol] 2022 Aug; Vol. 42, pp. 1-13. Date of Electronic Publication: 2022 May 06.

Abstract: The rhythm of the heart is not a stationary phenomenon, and therefore, incorporation of the dynamic Poincaré plot and tachogram provides additional diagnostic information to complement and expand waveform (P-QRST) analyses from the electrocardiogram. A...

Effects of β-blockers on ventricular repolarization documented by 24-hour electrocardiography in long QT syndrome type 2.

Publication Type: Academic Journal

Source(s): Heart rhythm [Heart Rhythm] 2022 Sep; Vol. 19 (9), pp. 1491-1498. Date of Electronic Publication: 2022 May 04.

Abstract: Background: Long QT syndrome (LQTS) is an inherited arrhythmia disorder characterized by ventricular repolarization abnormalities and a risk of sudden cardiac death. The electrophysiological components generating the high risk of arrhythmias in LQTS ar...

The association between continuous ambulatory heart rate, heart rate variability, and 24-h rhythms of heart rate with familial longevity and aging.

Publication Type: Academic Journal

Source(s): Aging [Aging (Albany NY)] 2022 Aug 16; Vol. 14 (18), pp. 7223-7239. Date of Electronic Publication: 2022 Aug 16.

Abstract: Aging is associated with changes in heart rate (HR), heart rate variability (HRV), and 24-h rhythms in HR. Longevity has been linked to lower resting HR, while a higher resting HR and a decreased HRV were linked to cardiovascular events and increased m...

At-home ECG monitoring with a real-time outpatient cardiac telemetry system during the COVID-19 pandemic.

Publication Type: Academic Journal

Source(s): Journal of osteopathic medicine [J Osteopath Med] 2022 Aug 10; Vol. 122 (10), pp. 503-508. Date of Electronic Publication: 2022 Aug 10 (Print Publication: 2022).

Abstract: Context: During the COVID-19 pandemic, essential in-person electrocardiogram (ECG) recordings became unfeasible, while patients continued to suffer from cardiac conditions. To circumvent these challenges, the cardiology clinic (Long Island Heart Rhythm...

Semi-Supervised Learning for Automatic Atrial Fibrillation Detection in 24-Hour Holter Monitoring.

Publication Type: Academic Journal

Source(s): IEEE journal of biomedical and health informatics [IEEE J Biomed Health Inform] 2022 Aug; Vol. 26 (8), pp. 3791-3801. Date of Electronic Publication: 2022 Aug 11.

Authors:

Abstract: Paroxysmal atrial fibrillation (AF) is generally diagnosed by long-term dynamic electrocardiogram (ECG) monitoring. Identifying AF episodes from long-term ECG data can place a heavy burden on clinicians. Many machine-learning-based automatic AF detecti...

Outcome of patients with early repolarization pattern and syncope.

Publication Type: Academic Journal

Source(s): Heart rhythm [Heart Rhythm] 2022 Aug; Vol. 19 (8), pp. 1306-1314. Date of Electronic Publication: 2022 Apr 05.

Abstract: Background: Syncope in patients with an early repolarization (ER) pattern presents a challenge for clinicians as it has been identified as an indicator of a higher risk of life-threatening ventricular arrhythmias (VAs).Objectives: This study aimed to a...

Diagnostic sensitivity and cost per diagnosis of ambulatory cardiac monitoring strategies in unexplained syncope patients.

Publication Type: Academic Journal

Source(s): PloS one [PLoS One] 2022 Jun 24; Vol. 17 (6), pp. e0270398. Date of Electronic Publication: 2022 Jun 24 (Print Publication: 2022).

Abstract: Diagnosing cardiac pauses that could produce syncopal episodes is important to guide appropriate therapy. However, the infrequent nature of these episodes can make detection challenging with conventional monitoring (CM) strategies with short-term ECG m...
