BACKGROUND Electrocardiogram (ECG) abnormalities following aneurysmal subarachnoid hemorrhage (SAH) have been well documented. Evidence suggests that ECG changes and cardiac dysfunction worsen outcome. Determining which patients are at most risk is unclear but important to ascertain. METHODS We prospectively studied clinical markers, cardiac abnormalities, and clinical outcomes in 20 patients...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

PURPOSE This retrospective study sought to determine the benefit of measurement of changes in plasma creatine kinase-myocardial band (CK-MB) levels in elective postoperative high risk surgical patients beyond that obtained from the surface 12 lead ECG. METHODS The charts of 111 patients admitted to the surgical intensive care unit (SICU) of a tertiary level university teaching hospital were r...

The relations between regional ventricular function and regional and surface ECGs were studied in eight conscious dogs during complete and partial coronary obstructions. Wall thickness and local ECGs were measured using an implanted sonomicrometer, and 11 subcutaneous electrodes were implanted in a modified McFee vectorcardiographic array. Complete obstruction of the circumflex coronary artery ...

Seventeen patients with non-cardiac chest pain were investigated by simultaneous ambulatory 24 hour ECG and oesophageal pH monitoring. While 11 patients lowered their oesophageal pH below 4 for a significant percentage, (3.4%) of recorded time and experienced chest pain, no simultaneous ECG changes occurred. In 10 patients chest pain was reproduced by an oesophageal acid perfusion test (Bernste...

BACKGROUND The use of a 12-lead electrocardiogram (ECG) in the screening of young athletes still has some controversies regarding the cost-benefit of the procedure. AIM We wanted to identify types and frequency of ECG changes in athletes in the Republic of Macedonia as well as its relation to age, gender, duration, frequency and type of sports. METHODS The study population included 256 trai...

Background: Arsenic toxicity as a result of consumption of hair removal agent has been rarely seen in last few years in comparison with the past. Case Presentation: In this case report, we presented a middle age woman referred to medical toxicology department due to epigastric pain and diarrhea following ingestion of hair removal agent. Urinary test for arsenic was positive. ECG changes and ele...

sis. It is doubtful that inadequate alpha-receptor blockade was a significant factor, since the blood pressure was well controlled with phenoxybenzamine. Although T wave changes may occur in patients with mitral valve prolapse9 (a condition suggested by this patient's initial physical examination), it seems unlikely that this would explain the close association between ECG changes and specific ...
