Left Ventricular Wall Findings in Non-Electrocardiography-Gated CE-CT After ECPR Might Be Useful for Diagnosis and Prognostic Prediction
Sugiyama et al. Critical Care (2019) 23:357 https://doi.org/10.1186/s13054-019-2624-1 RESEARCH Open Access Left ventricular wall findings in non- electrocardiography-gated contrast- enhanced computed tomography after extracorporeal cardiopulmonary resuscitation Kazuhiro Sugiyama1* , Masamichi Takahashi2, Kazuki Miyazaki1, Takuto Ishida1, Mioko Kobayashi1 and Yuichi Hamabe1 Abstract Background: Few studies have reported left ventricular wall findings in contrast-enhanced computed tomography (CE-CT) after extracorporeal cardiopulmonary resuscitation (ECPR). This study examined left ventricular wall CE-CT findings after ECPR and evaluated the association between these findings and the results of coronary angiography and prognosis. Methods: We evaluated out-of-hospital cardiac arrest patients who were treated with ECPR and subsequently underwent both non-electrocardiography-gated CE-CT and coronary angiography at our center between January 2011 and April 2018. Left ventricular wall CE-CT findings were classified as follows: (1) homogeneously enhanced (HE; the left ventricular wall was homogeneously enhanced), (2) segmental defect (SD; the left ventricular wall was not segmentally enhanced according to the coronary artery territory), (3) total defect (TD; the entire left ventricular wall was not enhanced), and (4) others. Successful weaning from extracorporeal membrane oxygenation, survival to hospital discharge, and predictive ability of significant stenosis on coronary angiography were compared among patients with HE, SD, and TD patterns. Results: A total of 74 patients (median age, 59 years) were eligible, 50 (68%) of whom had initial shockable rhythm. Twenty-three (31%) patients survived to hospital discharge. HE, SD, TD, and other patterns were observed in 19, 33, 11, and 11 patients, respectively. The rates of successful weaning from extracorporeal membrane oxygenation (84% vs. -

Sparse-Input Detection Algorithm with Applications in Electrocardiography and Ballistocardiography

Abstract: Sparse-input learning, especially of inputs with some form of periodicity, is of major importance in bio- signal processing, including electrocardiography and ballistocardiography. Ballistocardiography (BCG), the measurement of forces on the body, exerted by heart contraction and subsequent blood ejection, allows non- invasive and non-obstructive monitoring of several key biomarkers such as the respiration rate, the heart rate and the cardiac output. In the following we present an efficient online multi-channel algorithm for estimating single heart beat positions and their approximate strength using a statistical hypothesis test. The algorithm was validated with 10 minutes long ballistocardiographic recordings of 12 healthy subjects, comparing it to synchronized surface ECG measurements. The achieved mean error rate for the heart beat detection excluding movement artifacts was 4:7%. 1 INTRODUCTION Early signal-processing methods for BCG signals (Watanabe et al., 2005; Mack et al., 2009) concerned Cardiovascular diseases are among the leading causes estimation of heart rates averaged over a few sec- of death and severe health impairments both in high- onds using frequency-based methods.

Procedure Guideline for Planar Radionuclide Cardiac
Procedure Guideline for Planar Radionuclide Cardiac Ventriculogram for the Assessment of Left Ventricular Systolic Function Version 2 2016 Review date 2021 a b c d e e Alice Nicol , Mike Avison , Mark Harbinson , Steve Jeans , Wendy Waddington , Simon Woldman (on behalf of BNCS, BNMS, IPEM). a b Southern General Hospital, NHS Greater Glasgow & Clyde, Glasgow, UK Bradford Royal Infirmary, c d e Bradford, UK Queens University, Belfast, UK Christie Hospital NHS Foundation Trust, Manchester, UK University College London Hospitals NHS Foundation Trust, London, UK 1 1. Introduction The purpose of this guideline is to assist specialists in nuclear medicine in recommending, performing, interpreting and reporting radionuclide cardiac ventriculograms (RNVG), also commonly known as multiple gated acquisition (MUGA) scans. It will assist individual departments in the development and formulation of their own local protocols. RNVG is a reliable and robust method of assessing cardiac function [1-5]. The basis of the study is the acquisition of a nuclear medicine procedure with multiple frames, gated by the R wave of the electrocardiogram (ECG) signal. The tracer is a blood pool agent, usually red blood cells labelled with technetium-99m (99mTc). One aim of this guideline is to foster a more uniform method of performing RNVG scans throughout the United Kingdom. This is particularly desirable since the National Institute for Health and Clinical Excellence (NICE) has mandated national protocols for the pre-assessment and monitoring of patients undergoing certain chemotherapy regimes [6, 7], based on specific left ventricular ejection fraction (LVEF) criteria. This guideline will focus on planar equilibrium RNVG scans performed for the assessment of left ventricular systolic function at rest, using data acquired in the left anterior oblique (LAO) projection by means of a frame mode, ECG-gated acquisition method. -
