• 1. Cardiac EKG Monitoring
  • Continuous EKG - Computerized arrhythmia detection systems facilitate rapid detection of rhythm abnormalities and increase the likelihood of successful resuscitation.

 

Telemetry provides continuous electrocardiographic monitoring. It is the mainstay of surveillance monitoring for cardiac arrhythmia patients who are seriously ill, or have life-threatening cardiac arrhythmias.

Improved telemetry systems accommodate multiple channels of electrocardiographic data, thereby permitting analysis of both cardiac arrhythmias and ST segment changes. The continuously looping stored telemetry signal is presented in hourly full-disclosure format to permit a review of all continuous events that occurred during the previous 12 to 24 hours.

Ambulatory (Holter) electrocardiography (ECG) is used to evaluate cardiac rhythm abnormalities; it has also been used for assessing pacemaker and implantable cardioverter-defibrillator function, ischemia, late potentials, and heart rate variability.

The clinical utility of the ambulatory ECG recording lies in its ability to continuously examine the patient's cardiac rhythm over an extended period of time during normal routine activity, including any physical and psychological changes.

In contrast to the standard ECG, which provides a fixed picture of 12 leads of electrical events over a brief duration, extended ambulatory ECG (24 or 48 hours or 14 or 30 days) provides a view of only two or three leads of electrocardiographic data over an extended period of time, thereby permitting evaluation of changing dynamic cardiac electrical phenomena that are often transient and of brief duration. The increased sensitivity of the ambulatory ECG compared to other electrocardiographic forms of monitoring for detecting spontaneous, often highly variable, cardiac arrhythmias has been demonstrated in a variety of clinical studies.

The ambulatory ECG has proved to be one of the most cost-effective clinical tools in the diagnosis and assessment of cardiac arrhythmias (symptomatic or asymptomatic), prognostic assessment or risk stratification of various cardiac populations, in the evaluation of arrhythmia therapy, and for the evaluation of silent ischemia.
