Intended Use The SEER MC Ambulatory Digital Analysis Recorder is intended to provide ambulatory ECG signal and automated analysis of the recorded ECG data. Results of the automated analysis, when used in conjunction with an ECG review system, are intended to assist the physician in the interpretation of the recorded data. This information is not intended to serve as a substitute for the physician overread of the recorded ECG data. The SEER MC can collect and store up to 48 hours of continuous 2 or 3 channels of ambulatory ECG data. In addition, the SEER MC can record and analyze 12-lead ambulatory ECG data for definition of morphology shape and measurements, heart rate, rhythm, and ST segment trending.

Introduction: Manual Information pediatric (greater than 10Kg) patients in a clinical setting by qualified medical personnel. The SEER MC recorder, in its two- or three-channel mode of operation, detects the following: normal beats, ventricular beats, supraventricular beats, paced beats and artifact. This information, in conjunction with an ECG review system, documents the following: fastest and slowest heart rate, runs of ventricular beats, runs of supraventricular beats, pauses, ST segment changes, areas of atrial fibrillation, percentage of paced beats, prolonged QT, T-Wave Alternans, Heart Rate Turbulence, Heart Rate Variability and ECG strips associated with patient events and/or symptoms. The SEER MC in its 12-lead mode of operation, in conjunction with a ECG Review system, documents the aforementioned information and also measures and trends the following 12-lead parameters: PR interval, QT interval, QRS duration, ST measurements at J point plus 40, 60 and 80 milliseconds for all 12 leads and displays the Ventricular rate, and P, R and T axis for each 12-lead segment. The SEER MC is not intended to be used as a substitute for a standard, diagnostic-quality 12-lead electrocardiograph.
Functional Overview of SEER MC Application The SEER MC recorder provides ambulatory ECG signal, as well as automated analysis of the recorded data. Results of the automated analysis are intended to assist the physician in the interpretation of the recorded data. This information is not intended to serve as a substitute for the physician’s role in over-reading the recorded ECG data. The SEER MC can collect and store up to 48 hours of continuous 2 or 3 bi-polar channels of ambulatory ECG data. In addition, the SEER MC can acquire 12-lead ECG data, periodically or on demand. The 12-lead ECG data is acquired using 3 frontal plane electrodes, the Wilson Terminal, and 6 unipolar chest electrodes. The resulting 12-lead ECG data is identified using the standard lead name convention (I, II, III, aVR, aVF, aVL, & V1-V6). It should be noted that a quality diagnostic resting 12-lead ECG requires that the patient be at rest, in a supine position. Inappropriate body position or failure to minimize and recognize artifacts while recording the ECG may result in an incorrect measurement or diagnosis. As a result, diagnostic 12-lead ECGs are typically acquired in the presence of medical personnel, which administer the test and keep the patient calm and supine. However, unsupervised ambulatory Holter recording

Introduction: Manual Information provides an opportunity to assess cardiac function while the patient is undergoing routine, daily activities. The SEER MC allows the physician to monitor and record 12-lead ECG signals in the ambulatory environment. ECGs acquired in the ambulatory environment will include more artifact than ECGs acquired at rest. In addition, as the patient changes body position, the overall cardiac vector will change direction. As a result, the ambulatory ECG does not yield the same quality of information as the resting ECG. Furthermore, there is a large body of established criteria for resting electrocardiography that requires the measurement of small features in a single, 10-second ECG. This includes the recognition of small Q waves, on the order of 6ms in duration and 20uV in amplitude. Obtaining these small measurements in a single ECG is simply not practical in the ambulatory environment. In the ambulatory environment, each stored 10-second 12-lead ECG should be assessed as a sample that makes up a trend. The role of the SEER MC is to acquire these samples so that they can be trended over time. The SEER MC can trend the same measurements as available during treadmill exercise testing. These include QRS duration, PR interval, QT interval, ST deviation, and heart rate. The SEER MC can export 12-lead ECG measurements for the purposes of trending. In addition, the SEER MC can export each raw 12-lead, 10second record that corresponds to a single sample or measurement. As in most Holter applications, a review station is often used to assess the quality of the measurements in conjunction with the signal data. Trends can be accessed for outliers and confirmed with the accompanying signal data. This is also true of the data acquired by the SEER MC. As with most Holter analysis programs, signals or leads can be annotated by the program as having too much artifact to properly analyze. This is also true of the SEER MC. Noise annotations accompany the 12-lead recordings as well as the continuous 3-lead recordings. During conventional exercise testing, the 12-lead ECG is obtained via two different electrode positions. When the patient is at rest and supine, the limb electrodes are off of the torso, using the standard positions as defined for scalar 12-lead electrocardiography. While the patient is ambulatory, the limb electrodes are moved onto the torso. This standard modification of the 12-lead is referred to as the Mason-Likar position and it makes the ambulatory ECG more resilient in the presence of body motion. Extensive study has already been done to show the ECG differences that are exhibited when using the Mason-Likar electrode positions versus the conventional 12-lead resting electrode positions. Comparisons of ECGs acquired via the Mason-Likar and the

DANGER Do NOT use in the presence of flammable anesthetics.
WARNINGS Keep the conductive parts of lead electrodes and associated parts away from other conductive parts, including earth. Equipment failure hazard. Disconnect the leadwires from the patient before defibrillating. Otherwise, serious injury or death could result. This device is intended for use under the direct supervision of a licensed health care practitioner. Do NOT contact unit or patient during defibrillation. Strangulation hazard. Route all cables away from the patient's throat to avoid possible strangulation.
CAUTION U.S. Federal law restricts this device to sale by or on the order of a physician.
CAUTION Caution should be exercised when comparing serial 12lead ECGs that include both standard and altered lead positions. Altering limb lead positions during a 12-lead recording (i.e. torso placement of leads) can result in a 12 lead ECG with different properties (changes in inferior Q waves, changes in QRS axis) when compared to an ECG recorded with limb leads in the traditional position. ST segments measured using altered limb lead positions are not significantly affected
