Echocardiographic measurements of left ventricular end-systolic dimension and fractional shortening obtained in the supine position before and immediately after maximal upright exercise were evaluated in 11 normal volunteers, 35 patients with coronary artery disease and 17 patients without coronary artery disease. The time course of recovery from acute(More)
Acquired tricuspid valve incompetence was caused by a mobile thrombus attached to a permanent right ventricular endocardial electrode wire. The rarity of this complication is noted and the importance of its consideration in the proper setting is stressed. Diagnosis was made by angiography and confirmed at surgery.
A technique is proposed using the advantages of M-mode echocardiography for specific chamber measurement and 2-dimensional recordings for spatial orientation. Using data derived from radionuclide experience, a combined echocardiographic exercise test was developed. This test was used to evaluate 22 patients being studied for ischemic heart disease.

There have been a considerable number of cases litigating the validity of the forensic breath alcohol test and the potentials for a false positive ethanol reading. Recently, a claim asserted that the prior use of an over-the-counter (OTC) “oral care strip” normally used to suppress halitosis of the oral cavity, produced a false positive result when a(More)
