SUMMARY NOTES IN THE RECORD s20081 (Duration: 22:48:49.000) Starting time, recording date: 12/10/1994 Lead 0: ML2 Lead 1: MV2 Age: 39 Sex: F Comments: Lead 0: The rate-related ECG changes in lead 0 are generally characterized by J-point depression, ST flattening and down-sloping, and T-wave inversions. These changes are highly suggestive of ischemia. Lead 1: The few significant rate-related episodes in this lead show ST flattening and are not likely to represent ischemia if considered in isolation. This record is from the initial Long-Term ST Database of eleven 24-hour ST annotated ambulatory records (record s20538). Symptoms during Holter recording: No data Diagnoses: Palpitations Treatment: Medications: None Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: No history of 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: Normal Thallium/Stress echo: No data Left ventricular function: Normal Echocardiogram: Normal Coronary Arteriography: No Baseline ECG: No Holter Recording: Date: 12/10/1994 Recorder: No data ST ANNOTATIONS A.
