TransMedEx to deliver state-of-the-art in digital ambulatory electro-cardiography

Melville 24 July 2001TransMedEx, a provider of telemedicine monitoring and diagnostic services, is offering a Web-enabled Holter monitoring system, the only such device which can generate 12-leads of EKG data from a 3-channel recording using only five electrodes. In addition, the company also has expanded its trans-telephonic monitoring procedures to both identify transient symptoms and to respond to test data results with 3 distinct interventions appropriate for each test result.


The enhanced Holter monitoring system provides diagnostic data of comparable quality to a standard 12-lead EKG that requires 10 electrodes. The reduced number of patches of the Web Holter insures a patient's comfort and mobility. Test data is available to physicians through a secured Internet site using a standard browser, saving both patients and physicians valuable time.

A 12-lead view of the heart constitutes the industry standard for assessing the electrical conduction system of the heart, enabling physicians to identify the exact location of weakened heart muscles, as well as providing more comprehensive data on arrhythmias and ischemia. The 12-lead technology also offers additional diagnostic data on transient anginal episodes, as well as the detection of silent ischemia. Data quality is enhanced by the monitor's reduced artifact, or extraneous "noise", as the five electrodes are secured to bony points on the patient's torso.

"This is the state-of-the-art in digital ambulatory electro-cardiography and patient comfort", stated Yvonne F. Manfra, R.N., B.S.N., CCRN, Clinical Nurse Supervisor at TransMedEx's Cardiac Monitoring Laboratory. "The 3-channel 12-lead technology gives doctors a three-dimensional view of the heart, making the correct diagnosis faster and easier, while also speeding up the appropriate interventions. It is a major advance in mobile testing. Patients can go on with their lives as doctors get the highest quality, most comprehensive test data available."

A traditional, single channel Holter monitor records each heartbeat during a 24-hour period. The pager-sized, light-weight Web Holter delivers complete cardiographs from its five electrodes, and can run up to 48 hours on a single AA battery. By getting comprehensive test data as the patient goes about his daily routine, physicians are able to get an even more realistic profile of the heart than provided by the standard EKG, which uses the same 3-channel 12-lead technology but instead requires the patient to be tied to a stationary monitor.

Trans-telephonic cardiac event monitors use standard telephone lines to transmit test data to cardiac labs for analysis. Most cardiac event monitors are patient activated. If patients experience symptoms, such as palpitations or light-headedness, they push a button for an EKG to be automatically recorded. Patients play back the data recording over a standard telephone line to a monitoring centre for analysis.

TransMedEx's Cardiac Monitoring Triage Protocol was developed by board certified cardiologists in conjunction with TransMedEx's Cardiac Critical Care RN to provide a real time response for test data submitted via standard telephone lines. With the use of TransMedEx's specially designed protocol, patients who transmit their EKG recording receive assurance, advice, and 24/7 care.

If test results suggest a life-threatening emergency, TransMedEx personnel contact the patient directly, even before contacting the physician, to insure the patient gets to the hospital immediately. If the patient happens to be alone, TransMedEx personnel call the ambulance and then the prescribing physician. Test results for non-emergency arrhythmias are submitted to physicians within a few hours from TransMedEx's 24/7 monitoring centre.

"Our trans-telephonic cardiac monitors enable patients to capture their elusive symptoms for early identification and analysis", stated Mrs. Manfra. "Through the use of our Cardiac Monitoring Triage Protocol, we have been able to identify patients who needed a pacemaker inserted immediately. Often, a patient's telephone line can literally be a life line."

Underpinning TransMedEx's Cardiac Monitoring Triage Protocol procedures are state-of-the-art monitors. "Not every monitor is suited for every condition, such as ischemia", Mrs. Manfra added. "By matching specialised monitors to each suspected condition, physicians can maximise their diagnostic data. When there is a problem, our monitoring protocol insures the patients' safety, while keeping their physician updated on their condition."

TransMedEx has the widest selection of trans-telephonic cardiac monitors in the industry. In addition to carrying a 3-channel Holter monitor, it is the only United States distributor of a long-term 12-lead Angina Monitor, which enables physicians to identify and treat hard-to-capture transient anginal episodes, such as those associated with Coronary Artery Disease (CAD), ischemia, and angina.

Improved diagnosis of coronary circulatory problems may enable physicians to choose non-invasive interventions, such as pharmacological and life-style therapies. The trans-telephonic Angina Monitor can be worn up to 30-days at a time, offering doctors long-term angina analysis and a comprehensive overview of CAD and other circulatory problems. Cardiovascular diseases, including coronary heart disease, strokes, and high blood pressure, account for 40 percent of all U.S. deaths, according to a recent study by the Centers for Disease Control and Prevention.
