A test in which ultrasound is used to examine the heart. It allows accurate measurement of the heart chambers and offers far more sophisticated imaging. The echocardiograph is capable of displaying a cross-sectional “slice” of the beating heart, including the chambers, valves and the major blood vessels that exit from the left and right ventricles.
A device for making prolonged electrocardiograph (ECG) recordings on a portable flash memory device. The monitor is usually worn for 24 – 48 consecutive hours during normal activity. Since the recording is done on a continuous basis, Holter monitoring is much more likely to detect an abnormal heart rhythm when compared to the EKG which lasts less than a minute and is administered under controlled conditions.
Multiple / Serial Electrocardiograms (ECG)
An electrocardiogram (EKG or ECG) is a recording of the heart’s electrical activity as a graph or series of wave lines on a moving strip of paper. This gives the physician important information about the electrical conduction system of the heart. Many pathological conditions can be identified using ECGs including those caused by genetic, life style, or toxicological etiologies.
Platelet aggregometry is a functional test performed on whole blood or platelet-rich plasma. An agonist (platelet activator) is added to the suspension as a positive control and a dynamic measure of platelet clumping is recorded. ATP release is simultaneously measured using a luminescence marker. The test is used to assess the effects of a study drug on platelet aggregation.
The technique is used intermittently or continuously to non-invasively monitor oxygen saturation. A photo detector slipped over the finger measures transmitted light as it passes through the vascular bed, detects the relative amount of color absorbed by arterial blood, and calculates exact mixed venous oxygen saturation without interference from surrounding venous blood, skin, connective tissue, or bone.
Telemetry is a way to send data electronically from one point to another. In the telemetry unit, instruments record electronic data related to each patient. The instruments then send this data to a central area where it can be displayed on monitors for staff to observe. This allows staff to simultaneously monitor the hearts of multiple patients at once. Heart rhythms are continuously measured and data relayed to computers. Specially trained technicians monitor the computers.
|myocardial infarction||Myocardial infarction (MI) or acute myocardial infarction (AMI), commonly known as a heart attack, occurs when blood flow stops to a part of the heart causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Often it is in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired|
|cardiovascular clinical research||According to clinicaltrials.gov, cardiovascular trials currently account for 10 percent of all clinical trial participants. The acute nature of many of the health-related events associated with cardiovascular disease and the large number of individuals with the disease make this area of medical research unique in important ways.|
|platelet function testing||Platelet Function Tests also known as: Platelet Aggregation Studies; PFT; Platelet Function Assay; PFA Formal name: Platelet Function Tests Related tests: Complete Blood Count; Blood Smear; Platelet Count; PT and INR; PTT; Bone Marrow Aspiration and Biopsy; Coagulation Factors; von Willebrand Factor; Clopidogrel (CYP2C19 Genotyping)|
|platelet rich plasma||Platelet-rich plasma (Abbreviation: PRP) is blood plasma that has been enriched with platelets. As a concentrated source of autologous platelets, PRP contains (and releases through degranulation) several different growth factors and other cytokines that stimulate healing of bone and soft tissue.|
|platelet count||Platelets, also called thrombocytes (thromb- + -cyte, “blood clot cell”), are a component of blood whose function (along with the coagulation factors) is to stop bleeding by clumping and clotting blood vessel injuries.  Platelets have no cell nucleus: they are fragments of cytoplasm that are derived from the megakaryocytes of the bone marrow, and then enter the circulation. These unactivated platelets are biconvex discoid (lens-shaped) structures,|
|wireless medical telemetry||Wireless Medical Telemetry Service (WMTS) is a wireless service specifically defined in the United States by the Federal Communications Commission (FCC) for transmission of data related to a patient’s health (biotelemetry). It was created in 2000 because of interference issues due to establishment of digital television. The bands defined are 608-614 MHz, 1395-1400 MHz and 1427-1432 MHz. Devices using these bands are typically proprietary.|
