Several other studies have evaluated the usefulness of different ECG findings in diagnosing MI when LBBB is present. Smith et al. modified Sgarbossa's original criteria. [6] Smith modified Sgarbossa rule: at least one lead with concordant STE (Sgarbossa criterion 1) or; at least one lead of V1-V3 with concordant ST depression (Sgarbossa ...
The term unit record equipment also refers to peripheral equipment attached to computers that reads or writes unit records, e.g., card readers, card punches, printers, MICR readers. IBM was the largest supplier of unit record equipment and this article largely reflects IBM practice and terminology.
The manufacturing industries of ECG machines is now entirely digital, and many models incorporate embedded software for analysis and interpretation of ECG recordings with 3 or more leads. Consumer products, such as home ECG recorders for simple, 1-channel heart arrhythmia detection, also use basic ECG analysis, essentially to detect abnormalities.
Accounting documents or document records regroup every document that plays a role in the preparation of financial statements for a company, like income statements and balance sheets. They include records of monetary transactions, assets and liabilities, ledgers, journals, etc. Accounting documents and records are the physical objects upon which ...
Before the Codification, accounting standards lacked a consistent and logical structure. For the last 50 years, U.S. GAAP consisted of thousands of standards with multiple standard setters. The old U.S. GAAP were difficult to interpret, and the complexity of the standards made it hard for users to stay up to date.
Numerous diagnoses and findings can be made based upon electrocardiography, and many are discussed above. Overall, the diagnoses are made based on the patterns. For example, an "irregularly irregular" QRS complex without P waves is the hallmark of atrial fibrillation ; however, other findings can be present as well, such as a bundle branch ...
An example of the different treatment under cash and accrual accounting of a government's purchase of a building: Under cash accounting: The government's budget surplus decreases (or deficit increases) by the amount of cash used (or debt incurred) to acquire the building in the year the government takes ownership. After the year of acquisition ...
The original GDF specification was introduced in 2005 as a new data format to overcome some of the limitations of the European Data Format for Biosignals (EDF). GDF was also designed to unify a number of file formats which had been designed for very specific applications (for example, in ECG research and EEG analysis). [2]
