New Database: 927 high-resolution ECGs from patients undergoing exercise-testing available in the THEW

growthThis database includes 927 consecutive patients referred for exercise myocardial perfusion single photon emission computed tomography (SPECT) in two medical centers (Assuta Medical Center, and Sheba Medical Center). Exclusion criteria were cardiac pacemaker, atrial fibrillation at the time of testing and QRS duration ≥ 120 msec. The exercise protocol was as follow: beta blockers and calcium channel blockers were discontinued at least 48 hours before testing. A symptom-limited treadmill exercise test was performed using the Bruce protocol. High resolution 12 lead ECG (HyperQ™ Stress System, BSP Ltd, Tel Aviv, Israel) was continuously recorded throughout baseline, exercise and recovery phases. ECG acquisition was performed at a rate of 1000 samples/second using 16 bit resolution (measurement sensitivity < 0.15µV), with an analog frequency response of 0.05 to 125 Hz. Conventional ECG monitoring during the exercise test was either extracted automatically from the high resolution ECG traces or acquired using an additional ECG device (Q-Stress, Quinton Inc, WA), using a second set of 10 electrodes.

The patients underwent either stress/rest 99mTc-sestamibi gated SPECT, or stress/ redistribution 201Tl SPECT. 

The 99mTc-sestamibi protocol: a dose of 10 mCi 99mTc-sestamibi was injected at peak stress, and exercise was continued for an additional minute at peak stress, and two minutes at one lower exercise level. Gated SPECT acquisition was initiated 15-30 minutes later, using a 90° dual-detector gamma camera (Axis, Philips Medical Systems, Cleveland, OH, or CardiaL, GE Healthcare, Israel) equipped with LEHR collimators. Acquisitions were performed using 60 projections, 30-33 sec/projection, over 180° circular orbit. ECG gating was performed using 8-frames and a 100% acceptance window. Resting images were acquired 3.5-4 hours later, one hour after injection of an additional 30 mCi 99mTc-sestamibi, over 23-26 sec/projection.


The 201Tl protocol: a dose of 2.8-3.5 mCi 201Tl (adjusted to patient weight) was injected at peak exercise. SPECT acquisition was started 8-12 minutes following stress, using a 90° dual-detector gamma camera (Axis, Philips Medical Systems, Cleveland, OH, CardiaL, GE Healthcare, Haifa, Israel or Varicam, GE Healthcare, Haifa, Israel) equipped with LEHR collimators. Acquisitions were performed over 180° circular orbit using 60 projections, 22-26 sec/projection at Assuta Medical Center or 30 projections, 40 sec/projection at Sheba Medical Center. Redistribution images were acquired 3-4 hours later using 60 projections, 25-29 sec/projection at Assuta Medical Center or 30 projections, 40 sec/projection at Sheba Medical Center. Reinjection of 0.5-1 mCi 201Tl was administered whenever a severe perfusion defect was identified in the stress images. Images were reconstructed using filtered back projection, with a Butterworth post-filter. No attenuation or scatter correction was applied at Assuta Medical Center; attenuation correction was applied at Sheba Medical Center.

Perfusion images were visually scored using a 20-segment model of the left ventricle and a 5-point scale (0=normal tracer uptake, 1=mildly reduced, 2=moderately reduced, 3=severely reduced, 4=no uptake) (2). This analysis was performed by expert interpreters (TS or PC), over-riding automatic segmental scores, obtained by commercial software (QPS, Cedars Sinai Medical Center, Los Angeles, CA). The summed stress score and summed rest score were calculated as the sum of the individual segment scores for the stress and rest images and converted to percent total myocardium (% myocardium) by dividing by 80 (maximal potential score = 4 × 20). The amount of ischemic myocardium (IM) was calculated as the summed difference score (the difference between summed stress and summed rest scores) divided by 80. Patients were classified as: no ischemia or equivocal (IM<5%), mild ischemia (5%≤IM<10%) and moderate/severe ischemia (IM≥10%) (3, 4).

High-Frequency QRS Analysis: From the Research Lab to the Clinical Market

By Guy Amit, PhD., Biological Signal Processing Ltd., Tel-Aviv, Israel

Ischemic heart disease (IHD) is a major healthcare problem worldwide. In the US alone, there are 1 7 . 6 million IHD patients, and the estimated annual incidence of new and recurrent myocardial infarction is estimated to be 935,000 (1). ECG retains its central role as the first-line diagnostic modality for ischemic heart disease workup in both chronic and acute presentations. Electrocardiographic detection of myocardial ischemia is typically based upon identification of repolarization abnormalities, manifested as changes in the ST-T segment. However, ischemia also induces changes during the depolarization phase, which can be detected and quantified by analyzing the high-frequency components of the QRS complex (HFQRS). HFQRS components are very low in amplitude and are typically filtered out by conventional ECG devices. The HFQRS signal originates from the fragmentation of the electrical activation wavefront in the myocardium, caused by the branching nature of the conduction system. In ischemic regions of the myocardium, local slowing of conduction velocity reduces the wavefront fragmentation, causing changes in the intensity and morphology of HFQRS signals (2). Over the last 30 years, HFQRS have been extensively studied in computer simulations, animal models, humans during coronary balloon occlusion and patients undergoing exercise test (2-7). Analysis of HFQRS has been reported to be more sensitive and specific than conventional ECG interpretation in detecting exercise-induced ischemia (5-7). Recently, Biological Signal Processing Ltd. (BSP) has introduced the HyperQ™ EX300 stress system, which provides automated HFQRS analysis in a commercially-available exercise ECG system. The system's technology is based upon sophisticated signal processing algorithms that perform accurate QRS alignment and averaging, band-pass filtering in the frequency range of 150 to 250 Hz, and computing of the root-mean-square intensity of the HFQRS signal. The trend of HFQRS intensity in 12 leads throughout the exercise test is then examined, and the relative intensity reduction is used as an index of ischemia (Figure 1).

The HyperQ index of ischemia was studied in 996 patients (age 58.9±10.2 years, 670 men), referred for exercise nuclear scan, which was used as the gold standard of ischemia. HyperQ response correlated with severity of ischemia, and was more sensitive (69% vs. 39%, P<0.005) and more specific (86% vs. 82%, P<0.05) than ST segment analysis. Multivariate logistic regression indicated considerable incremental diagnostic value of HyperQ over pre-test likelihood of CAD and exercise parameters (7).
Ongoing research efforts are aimed to establish HFQRS analysis as a routine adjunct to workup of IHD, and to develop new clinical applications of the technology. Of particular interest are the utilization of HFQRS for early detection of acute myocardial ischemia in patients presenting with chest pain, continuous monitoring of patients in risk of transient ischemic episodes and identification of ischemia from intra-cardiac pacing leads.
