SUMMARY NOTES IN THE RECORD s20601 (Duration: 23:40:00.000) Starting time, recording date: 14:44:00 11/07/1988 Lead 0: V4 Lead 1: MLIII Age: 46 Sex: F Comments: There is an ischemic episode in lead 1 at 22:22:30 which is corrupted with noise. This patient demonstrated a few ischemic episodes, manifested by ST depression in both leads. The changes were minimal, and in some cases the associated heart rate increases introduced severe noise. Symptoms during Holter recording: No data Diagnoses: Syndrome X Treatment: Medications: None Balloon Angioplasty: No data Coronary Artery bypass Grafting: No data History: Effort and resting angina 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: Positive for ST depression of 0.1 mV in V3-V6 Thallium/Stress echo: No data Left ventricular function: Normal Echocardiogram: No data Coronary Arteriography: Normal coronary tree Baseline ECG: Normal Holter Recording: Date: 11/07/1988 Recorder: ICR ST ANNOTATIONS A.
