We report a case of acute pulmonary embolism with hemodynamic instability diagnosed by a computed tomography pulmonary angiogram. The patient developed pulseless electrical activity during systemic thrombolytic therapy with recombinant tissue plasminogen activator. Successful return of spontaneous circulation was achieved after immediate cardiopulmonary resuscitation with chest compressions for 6 min. His electrocardiogram (ECG) on arrival in the emergency department displayed sinus tachycardia, an S wave in lead I, a Q wave in lead III, incomplete right bundle branch block (RBBB), T-wave inversion (TWI) in leads V1-V3, ST elevation in leads aVR and V1, and ST depression in leads I, II, III, aVF, and V4-V6...

Blood flow is a clinical metric for monitoring of cardiovascular diseases but current measurements methods are costly or uncomfortable for patients. It was shown that the interaction of the magnetic field (B 0) during MRI and blood flow in the body, through the magnetohydrodynamic (MHD) effect, produce voltages (V MHD) observable through intra-MRI electrocardiography (ECG), which are correlated with regional blood flow. This study shows the reproducibility of V MHD outside the MRI and its application in a portable flow monitoring device...

BACKGROUND: Practice guidelines recommend regional systems of care for out-of-hospital cardiac arrest. However, whether emergency medical services should bypass nonpercutaneous cardiac intervention (non-PCI) facilities and transport out-of-hospital cardiac arrest patients directly to PCI centers despite longer transport time remains unknown. METHODS AND RESULTS: Using the Cardiac Arrest Registry to Enhance Survival with geocoding of arrest location, we identified out-of-hospital cardiac arrest patients with prehospital return of spontaneous circulation and evaluated the association between direct transport to a PCI center and outcomes in North Carolina during 2012 to 2014...

The ABC of paediatric ECG interpretation In paediatric patients, ECG is used as a tool for investigation of arrhythmias, chest pain, syncope, intoxications and congenital heart abnormalities. Paediatric ECGs differ significantly from adult ECGs, and change gradually during childhood, largely because of the changes that start with the transition of foetal circulation at birth. This evolution is most prominent during the first year of life, but it is not until the late adolescent years that the ECG corresponds to that of adults...

A 75-year-old man collapsed on a golf course and received cardiopulmonary resuscitation from a bystander, including the use of a public automated external defibrillator (AED). The AED was discharged once, with return of spontaneous circulation. An air ambulance crew found the patient haemodynamically stable, with no acute abnormalities on a 12-lead ECG. He had reduced consciousness and a dilated left pupil. On contacting the patient's wife by telephone, she said that he had fallen and hit his head earlier that day...

BACKGROUND: Intermittent negative pressure (INP) applied to the lower leg and foot increases foot perfusion in healthy volunteers. The aim of the present study was to describe the effects of INP to the lower leg and foot on foot macro- and microcirculation in patients with lower extremity peripheral arterial disease (PAD). METHODS: In this experimental study, we analyzed foot circulation during INP in 20 patients [median (range): 75 (63-84yrs)] with PAD. One leg was placed inside an air-tight vacuum chamber connected to an INP-generator...

Vasospastic angina (VSA) is caused by endothelial dysfunction and hypercontraction of vascular smooth muscle cells. Although oxidative-stress can induce endothelial dysfunction, the relationship of VSA and the oxidative-stress marker malondialdehyde-modified low density lipoprotein (MDA-LDL) remains unclear. PURPOSE: Serum MDA-LDL was evaluated in candidate VSA patients.The subjects were 84 patients admitted to our hospital because of chest pain at rest. We stratified the patients into 3 groups; definite VSA, suspected VSA, and unlikely VSA according to a Japanese Circulation Society (JCS) guideline...

Background. Atrial fibrillation (AF) is an important cause of embolic stroke of undetermined source (ESUS). Imaging-patterns like multiple infarcts, simultaneous involvement of different circulations, infarcts of different ages, and isolated cortical infarcts are likely to indicate cardioembolic stroke. The aim of our study was to evaluate the association between embolic stroke patterns, ESUS, and the new diagnosis of AF. Methods. Stroke etiology and imaging characteristics from patients included in the Find-AF study were obtained...

Folliculogenesis is a process that depends on angiogenesis, in which VEGF and Notch signaling pathway members are involved. Although this pathway is present in preantral and antral follicular structures during the second stage of folliculogenesis, this association has not been described. Therefore, this study aimed to identify VEGF and Notch2 in ovary structures of infantile rats after induction of follicular development with a gonadotropin stimulus. In order to explore this possibility we analyzed rat ovary morphology from days 10-25 after birth; subsequently, the transition from preantral follicle to an antral stage was analyzed by the induction of follicular development with equine chorionic gonadotropin (eCG) and VEGF and Notch were identified in the rat ovary by fluorescence...

The aim of this study is to demonstrate the enhanced therapeutic efficacy of anticancer drugs on drug-resistant breast cancer using multicomponent microemulsions (ECG-MEs) as an oral delivery system. The etoposide-loaded ECG-MEs were composed of coix seed oil and ginsenoside Rh2 (G-Rh2), both of which possess not only the synergistic antitumor effect with etoposide, but also have excipient-like properties. Orally administrated ECG-MEs were demonstrated to be able to accumulate at the tumor site following crossing the intestines as intact vehicles into the blood circulation...

PURPOSE: Progressive impairment of hemodynamics in patients with Fontan circulation is common, multifactorial, and associated with decreased quality of life and increased morbidity. We sought to assess hemodynamic differences between patients with preserved (preserved Fontans) and those with impaired circulation (impaired Fontans) after pulmonary vasodilation using oxygen and under forced breathing conditions. MATERIALS AND METHODS: Real-time phase-contrast cardiovascular magnetic resonance was performed using non-ECG triggered echo-planar imaging (temporal resolution=24 to 28 ms) in the ascending aorta (AAo) and superior vena cava (SVC)/inferior vena cava (IVC) on room air, after 100% oxygen inhalation (4 L/min; 10 min) and on forced breathing in 29 Fontan patients (17...

Hydrochlorothiazide became one of the most commonly prescribed first-line antihypertensive medication, though its use is often complicated with serious side-effects. A 66-year-old female patient with a history of hypertension had suffered a transient loss of consciousness, and referred to our cardiology unit with an ST-segment elevation and giant negative T-waves in V1-2 ECG leads, long QT-segment and elevated serum creatine-kinase (5392 U/L) and troponin I (4,357 ng/ml) levels. Acute myocardial infarction was not proven (later coronarography revealed preserved coronary circulation), but severe hyponatraemia and hypokalaemia was detected, explaining a possible symptomatic seizure, and which could be accounted for a 25 mg daily hydrochlorothiazide antihypertensive treatment and - as a precipitating insult - a one-week history of gastroenteritis...

OBJECTIVES: The authors aimed to evaluate the role of post-resuscitation electrocardiogram (ECG) in patients showing significant ST-segment changes on the initial ECG and to provide useful diagnostic indicators for physicians to determine in which out-of-hospital cardiac arrest (OHCA) patients brain computed tomography (CT) should be performed before emergency coronary angiography. BACKGROUND: The usefulness of immediate brain CT and ECG for all resuscitated patients with nontraumatic OHCA remains controversial...

Survivors of out-of-hospital cardiac arrest (OHCA) have high mortality and morbidity. An acute coronary event is the most common cause of sudden cardiac death. For this reason, coronary angiography is an important diagnostic and treatment strategy for patients with postcardiac arrest. This study aimed to identify the correlation between postreturn of spontaneous circulation (ROSC) on an electrocardiogram (ECG) and results of coronary angiography of OHCA survivors.We collected data from our OHCA registry from January 2010 to November 2014...

Cardiopulmonary resuscitation (CPR) must be interrupted for reliable rhythm analysis in current automatic external defibrillators (AEDs) because of artifacts produced by chest compressions. However, interruptions in CPR adversely affect the restoration of spontaneous circulation (ROSC) and survival. Suppressing CPR artifacts by digital signal processing techniques is a promising method to enable rhythm analysis during chest compressions, which would eliminate CPR interruptions for rhythm analysis. Although numerous methods have been developed to suppress CPR artifacts, the accuracy of rhythm analysis is still inadequate due to the residual artifact components in the filtered signal...

A 58 years healthy old woman was admitted to the Emergency Department (ED) with cardiac arrest due to ventricular fibrillation (VF). Appropriate cardiopulmonary resuscitation (CPR), multiple DC shocks and oro-tracheal intubation (OTI) were effective to induce recovery of spontaneous circulation (ROSC). After ROSC was achieved, the electrocardiogram (ECG) showed an idio-ventricular rhythm with atrioventricular dissociation. A transcutaneous pacing was hence applied and the patient was administered with isoproterenol...
