Volunteers with normal hearing were tested for vegetative balance with the aid of vegetative reflexes and with the aid of the atropine test. The effect of white noise stimulated on hearing thresholds was then investigated together with their recovery. The vegetative system was affected
We present a case of a complete atrioventricular block (AV block) with different aberrancy patterns during sinus rhythm and escape rhythm. A 66-year-old woman visited our emergency department complaining of sudden onset dizziness and fatigue over the past thirty minutes. Her medical history was
Maximum velocity and amplitude of repetitive ( 1-per-second) 30 degrees saccadic eye movements were quantitatively assessed for 4 minutes before and after intravenous edrophonium chloride as a diagnostic test for myasthenia gravis. Atropine was given initially to suppress muscarinic side effects.
BACKGROUND
Failure to reach 85% of maximal predicted heart rate (MPHR) during exercise may render a myocardial perfusion single photon emission computed tomography (MPS) study nondiagnostic for ischemia detection. Although commonly used to increase heart rate (HR) during dobutamine stress, the
BACKGROUND
Treadmill stress testing (TMST) is a valuable diagnostic test for ischemic heart disease. However, the inability to achieve the target heart rate because of either chronotropic incompetence or poor exercise capacity is a major limitation to its utility. We evaluated the usefulness of
OBJECTIVE
Exercise stress test (EST) is one of the main diagnostic and prognostic tests for ischemic heart disease. However, its usefulness depends on achieving target heart rate, then chronotropic incompetence and poor exercise capacity limits its utility. We evaluated the usefulness of atropine
BACKGROUND
We aimed to assess whether atropine administration is safe and feasible in patients unable to reach the minimal heart rate (HR) required (80% of age-predicted HR) in myocardial scintigraphic studies after exercise stress testing (EST).
RESULTS
We studied 108 patients who underwent
BACKGROUND
Failure to reach 80% of maximal predicted heart rate (HR) during exercise may render a myocardial perfusion single photon emission computed tomography (SPECT) study non-diagnostic for ischemia detection. We sought to investigate the injection of atropine in patients who fail to achieve
Selected kinesiological parameters were studied in the gastrocnemius muscle of frog, R. hexadactyla Lesson, under different treatments with malathion and atropine. There is an apparent decrease of twitch amplitude, half contraction time, half relaxation time, twitch duration and fatigue time in
A double-blind technique was used for studying the psychic and somatic effects of premedication with flunitrazepam, innovar and a placebo in 116 patients. Innovar and the placebo produced the same results. Flunitrazepam reduced anxiety and apprehension and had a significantly higher amnesic effect.
The goal of the present study was to document the intrinsic origin of atrioventricular nodal functional properties (recovery time, facilitation, and fatigue) in two groups of six superfused isolated rabbit heart preparations. These properties were determined from recovery curves (A2H2 versus H1A2
Case Study Mr. D., a 55-year-old male, presented to the medical oncology service with a diagnosis of stage III adenocarcinoma of the sigmoid colon. He presented 7 weeks post sigmoid colectomy with lymph node resection and was initiated on adjuvant chemotherapy with CAPOX (capecitabine [Xeloda] and
The most disabling form of Parkinsonism is that occurring after encephalitis. It may occur in persons of any age. The results of surgical treatment, which has been used for the most part only for seriously handicapped patients, have been discouraging in general, although in a few isolated
