Medicomp’s Mobile Cardiac Telemetry solution is the SAVI Wireless: a small portable heart monitoring system that can automatically capture and transmit your heart’s abnormal activity, even if you don’t feel a symptom. It consists of two main parts: the Pendant and the SmartPhone. The Pendant and SmartPhone work together to capture and analyze your heart’s ECG in real-time. The important data is then sent to Medicomp’s Cardiac Monitoring Center over a cellular network.
Holter Monitoring is a medically prescribed, non-invasive procedure that is conducted on patients who are capable of walking or moving around. This test is called a "Holter" procedure, named after the scientist who first developed it about 50 years ago. The Holter test is a scaled-down version of the 12-lead electrocardiogram (EKG) in that only a few leads are actually monitored. The test duration, however, is typically 24 hours, instead of the typical, several seconds required for an EKG.
Holter Monitoring is used as a screening tool in the evaluation of patients with symptoms of various forms of heart disease, or in situations where the physician suspects cardiac pathology in the absence of symptoms. Symptoms such as palpitations, lightheadedness or fainting may be caused by disturbances in the electrical signals that control the heart muscle contractions. These disturbances can be random, spontaneous, sleep-related, or emotion- or stress-induced.
Holter Monitoring is an ideal test because the patient assumes normal, daily activities, increasing the likelihood that he or she will experience the precise situations that can trigger symptoms or cardiac events. This allows correlation of any rhythm problems or abnormalities with activities and/or symptoms. In the opposite sense, Holter Monitoring can also be used to "rule out" cardiac causes of patients' symptoms if these symptoms occur in the absence of any cardiac event.
The patient wears the battery-powered Holter Monitor, a "box" weighing a few ounces, on a belt or shoulder strap. Adhesive patches on the patient's chest conduct the electrical signals of the heart to the Holter Monitor through wire connections. The monitor, in turn, stores and analyzes the data. The patient wears the monitor for 24 hours and assumes normal activities, including sleep periods.
At the end of the 24 hours, the data from the monitor is transferred to the base station computer, where a licensed heart nurse or technician reviews and, if required, edits the data in a procedure known as "scanning". A report is generated that documents and trends any abnormalities that occurred, and is submitted to the physician for final interpretation.
Cardiac Event Monitoring is a medically prescribed, non-invasive procedure that is conducted on patients who report symptoms that may be cardiac in origin, and that occur infrequently-usually three times or less in one week. The term "Event Monitoring" is used because traditionally the test relied on the occurrence of symptoms, or "events"; that is, the patient activated the Event Monitor to record his/her ECG when symptoms occur. Medicomp monitors also have the ability to auto-capture events even if the patient does not feel the symptom to initiate the recording. The testing period can last up to 30 days, which means that the patient carries the Event Monitor for this length of time.
Cardiac Event Monitoring is used to evaluate patients who experience transient, infrequent symptoms that may indicate various forms of heart disease. Symptoms such as shortness of breath, dizziness and palpitations are some of the common patient complaints. These symptoms may be caused by disturbances in the electrical signals that control the heart muscle contractions. The disturbances can be random, spontaneous, or emotion- or stress-induced.
Patients carry the small, battery-powered Event Monitor on their person for the duration of the testing period. The monitor may or may not be directly attached to the chest using wires and adhesive patches. The patient triggers the monitor to record the ECG when a symptom occurs. Medicomp monitors also have the ability to automatically capture clinically relevant ECG, even if the patient does not feel a symptom. After the recording is complete, the patient transmits the ECG via phone to a Monitoring Center. The Monitoring Center staff reviews the tracings and notifies the patient's physician immediately, if appropriate. A report is generated and forwarded to the physician.
