High-pitch non-gated scans on the second and third generation dual-source CT scanners: comparison of coronary image quality

To examine differences in image quality of the coronary arteries when performing high-pitch non-electrocardiography (ECG)-gated scans on the second-generation (2G) and third-generation (3G) dual-source CT scanners.

ConclusionsNoninvasive fetal heart rate monitoring using maternal abdominal wall electrodes to detect fetal cardiac activity more reliably reproduced the computerized analysis of heart rate patterns derived from a direct fetal scalp electrode than did traditional ultrasound ‐based monitoring. Abdominal‐fetal ECG should, therefore, be considered a primary option for externally monitored patients.

AbstractBackgroundThe prognostic value of myocardial perfusion imaging (MPI) in patients with known coronary artery disease (CAD) and high exercise capacity is still unknown. We sought to determine the MPI additional prognostic value over electrocardiography (ECG) stress testing alone in patients with known CAD who achieved  ≥ 10 metabolic equivalents (METs).Methods and ResultsWe evaluated 926 patients with known CAD referred for MPI with exercise stress. Patients were followed for a mean of 32.4  ± 9.7 months for the occurrence of all-cause death or nonfatal myocardial infarction...

Conclusions. Our results show that the division of MI diagnoses to STEMI and NSTEMI is not reliable in the Finnish HDR. These diagnoses should not be used as outcomes in scientific research without additional verification from the original ECGs. PMID: 31701776 [PubMed - as supplied by publisher]

Written by Meyers, edits by SmithA 50-ish year old man was working construction when he suddenly collapsed. Coworkers started CPR within 1 minute of collapse. EMS arrived within 10 minutes and continued CPR and ACLS, noting alternating asystole and sinus bradycardia during rhythm checks. He received various ACLS medications and arrived at the ED with a perfusing rhythm.Initial vitals included heart rate around 100 bpm and BP 174/96. Here is his initial ECG, very soon after ROSC:What do you think?Sinus tachycardia.  There is incomplete RBBB (QRS duration less than 120 ms).  There is diffuse STD, maximal in V4-V5 a...

Rationale: Acute myocardial infarction is usually caused by coronary atherosclerotic plaque disruption (rupture or erosion), also including other uncommon etiologies. Pulmonary epithelioid hemangioendothelioma (PEH) is a rare low to intermediate malignant vascular tumor originating from vascular endothelial cells. Here, we report a rare case of acute ST-segment elevation myocardial infarction (STEMI) due to extrinsic compression of left coronary artery from PEH. Patient concerns: A 63-year-old woman with pulmonary nodules received left pulmonary nodulectomy, and the pathological examination indicated PEH. Five months ...

Authors: Kuyumcu MS, Özbay MB, Özen Y, Yayla Ç Abstract Objectives. Frontal plane QRS-T angle is a novel marker of myocardial repolarization, and an increased frontal plane QRS-T angle is associated with adverse cardiac outcomes. Slow coronary flow may cause fatal cardiac arrhythmias by causing electrical abnormalities and altering ventricular repolarization. We aimed to evaluate the frontal plane QRS-T angle in patients with slow coronary flow. Design. A total of 60 consecutive patients with slow coronary flow and 60 consecutive patients with normal coronary flow were enrolled into the study. Labo...
