The advent of computerised electrocardiography has been of prime importance for the storage and retrieval of data, but none of the available systems is of universal application for analysis of patterns. Future needs require hierarchical systems of increasing degrees of complexity, depending on the source of requests, and there should be appropriate provision for review by cardiologists before t...

A svstem of miultiple-lead exeicise electrocardiography has been applied to the study of 107 normal subjects and 67 patients with angina pectoris. The results of this test are compared to those of coronary cinearteriography in 84 patients. In-exercise ECGs gave useful additional information in 59% of the angina patients but were essential for interpretation in 9%. It added considerably to the s...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...

background: milk fever in cattle, sheep and goats occurs  around the time of parturition and is caused by hypocalcemia. objectives: the aim of this study was to investigate the physiological effects of experimental hypocalcemia on electrocardiography, hematology and serum biochemical changes in markhoz goat breed. methods: ethylene diamine tetra- acetate solution 4.6% was intravenously infused ...

STUDY OBJECTIVE There have been 15 published cases of probable pentamidine-induced torsade de pointes (TdP). A prospective analysis of this complication of therapy is valuable considering the high frequency of Pneumocystis carinii pneumonia in the AIDS population, and the role of pentamidine in its therapy. DESIGN Open, nonrandomized, prospective study of HIV-infected patients receiving intra...

Patient biopotentials are usually measured with conventional disposable Ag/AgCl electrodes. These electrodes provide excellent signal quality but are irritating for long-term use. Skin preparation is usually required prior to the application of electrodes such as shaving and cleansing with alcohol. To overcome these difficulties, researchers and caregivers seek alternative electrodes that would...

cancer patient receive various cytotoxic drugs in association with antiemetic drugs such as 5ht3 receptor antagonists as their chemotherapy regimen. 5ht3 receptor antagonists have been reported to produce changes in ecg parameter. there are only a few studies about cardiovascular events of these drugs in patient receiving potentially cardiotoxic chemotherapies. the subject of this study is to e...

background central venous catheterization is done frequently in cardiac surgery and intensive care settings. faulty positioning of the catheter can cause many complications. objectives the aim of our study was to study the average depth of insertion and formulate a general guideline through the right internal jugular vein (ijv). patients and methods the right ijv was cannulated over a period of...
