Continuous lead electrocardiographic ECG monitoring can identify transient myocardial ischemia, even when asymptomatic, among patients with suspected acute coronary syndrome ACS. In this article we describe our method for initiating patient monitoring using a Holter device, downloading the ECG data for off-line analysis, and how to utilize the ECG software to identify transient ischemia. Each year, an estimatedAmericans will have a new coronary attack, or acute coronary syndrome ACS. The pathophysiology of ACS involves rupture of an atherosclerotic plaque; hence, treatment is aimed at plaque stabilization in order to prevent cellular death. Continuous lead ECG Mde Escort Hastabaşi Moni Tör, which is both inexpensive and non-invasive, can identify transient episodes of myocardial ischemia, a precursor to MI, even when asymptomatic. However, continuous lead ECG monitoring is not usual hospital practice; rather, only two leads are typically monitored. Information obtained with lead ECG monitoring might provide useful information for deciding the best ACS treatment. Permission to proceed with this study was obtained from the Institutional Review Board of the hospital and the university. Research nurses identify hospitalized patients from the emergency department and telemetry unit with suspected ACS. Patients are also maintained on the routine bedside ECG monitoring system per hospital protocol. Off-line ECG analysis is done using sophisticated software and careful human oversight. According to the most recent American Heart Association statistics, coronary artery disease CAD was estimated to be responsible for 1. Because of the prevalence of CAD, clinicians working in hospitals are likely to encounter these patients frequently. Each year, nearlyAmericans will have a new coronary attack, or acute coronary syndrome ACS. Electrocardiographic changes indicative of ischemia occur within seconds of diminished coronary blood flow. The lead ECG has important advantages over both symptoms and biomarkers in identifying MI in that it is non-invasive, inexpensive, and if maintained continuously can identify transient ischemia, even when it is clinically silent. While lead ECG monitoring is ideal because multiple areas of the heart are assessed, typical hospital practice incorporates monitoring with only two ECG leads. In our study, continuous lead ECG Holter recorder is used to capture ischemia. While computer-assisted ST-segment software works well for detecting transient ischemia, accurate analysis requires careful, expert human oversight. Important factors to consider during analysis include 1 artifact, 2 the consistency and accuracy electrode placement, 3 body position changes, 4 drug effects, and 5 sudden waveform changes. Artifact: Because clinically significant ST-segment changes are as small as microvolt one small box on the ECG papernoisy signal from muscle artifact can significantly hinder analysis. Most artifacts are related to improper skin preparation. Consistency and Accuracy of Electrode Placement: False positive ST-segment changes can occur when electrodes are moved or removed during monitoring. Body Position Changes: Studies using continuous ST-segment monitoring have shown that some patients can exhibit concomitant QRS and ST-segment amplitude changes during body position changes i. This had a direct effect on the distance of the left ventricle from the chest electrodes and resulted in an increase in the amplitude of the R-wave in the ECG leads over this myocardial territory. These changes have been confirmed by others. Drugs that alter the ST-segment are particularly important since they lead to a misdiagnosis of myocardial ischemia. Nevertheless, patients taking these drugs can be monitored for acute ST-segment changes that may indicate acute myocardial ischemia. Sudden Waveform Changes: Transient conditions, such as arrhythmias, right- or left bundle branch block BBBand intermittent ventricular paced beats, can distort the ST-segment and lead to a false-positive ischemia diagnosis. In summary, continuous ST-segment monitoring is an excellent tool for identifying transient myocardial ischemia in patients with suspected ACS. However, this method requires that careful application of electrodes and leads wires is performed at the initiation and throughout monitoring. This method also requires careful human oversight in order to eliminate false positive ST-segment changes. A display indicates if an ECG lead has become detached and also provides an internal clock for recording of diary events. The software allows analysis of continuous ECG recordings to determine the quality of the signal, presence of arrhythmias, and ischemia. Research assistants with experience working with the cardiac patient population collect the ECG Holter data. A training session at the start of the study was scheduled to ensure the quality and consistency of the study protocol. Bi-weekly research team meetings ensure that recruitment goals are being met, challenges are discussed, and results of inter-rater reliability tests can be shared. Both of these methods will be explained in a step-by-step manner in the subsequent section. The initial analysis of the ECG data includes an assessment of the ST-segment trends in each of the 11 leads using the H-Scribe software. This method is a quick and easy assessment used to evaluate hours of ECG data for the presence of possible transient myocardial ischemia. Figure 1.
