SUMMARY NOTES IN THE RECORD s20011 (Duration: 22:52:59.000) Starting time, recording date: 17:08:00 09/12/1994 Lead 0: ML2 Lead 1: MV2 Age: 58 Sex: M Comments: Lead 0: All ST change episodes appeared to be rate-related non-ischemic episodes characterized by J-point depression and scooping of the ST segment. Lead 1: All episodes in lead 1 are compatible with heart-rate induced non-ischemic changes and are so labeled. It is recognized that this is an arbitrary decision. This record is from the initial Long-Term ST Database of eleven 24-hour ST annotated ambulatory records (record s20689). Symptoms during Holter recording: None reported Diagnoses: No coronary artery disease Treatment: Medications: None Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: ST depressions but no coronary artery disease Hypertension: No Left ventricular hypertrophy: No Cardiomyopathy: No Valve disease: No Electrolyte abnormalities: No Hypercapnia, anemia, hypotension, hyperventilation: No Atrioventricular nodal conduction delay: No Intraventricular conduction block: No Previous Myocardial Infarction: No Previous tests: ECG stress test: Yes Date: No data Findings: Ischemic ST changes at high work load Thallium/Stress echo: Negative Left ventricular function: Normal Echocardiogram: Normal Coronary Arteriography: No significant disease Baseline ECG: Normal sinus rhythm Left atrial abnormality Mild ST elevation V2-V4 consistent with early repolarization Holter Recording: Date: 09/12/1994 Recorder: No data ST ANNOTATIONS A.
