SUMMARY NOTES IN THE RECORD s20381 (Duration: 23:50:49.988) Starting time, recording date: 11:49:00 14/02/1992 Lead 0: 0 Lead 1: 1 Age: No data Sex: No data Comments: There is one clear ischemic episode at the end of the record, present in both leads. In lead 0 there were a few very minor ST depressions which met the criteria for significance, and which were felt to be "rate-related". These changes were not present in lead 1. There were periods of noise in the data. Electrode locations were not recorded. Symptoms during Holter recording: No data Diagnoses: Coronary artery disease Treatment: Medications: No data Balloon Angioplasty: No data Coronary Artery bypass Grafting: No data History: Hypertension: No data Left ventricular hypertrophy: No data Cardiomyopathy: No data Valve disease: No data Electrolyte abnormalities: No data Hypercapnia, anemia, hypotension, hyperventilation: No data Atrioventricular nodal conduction delay: No data Intraventricular conduction block: No data Previous Myocardial Infarction: No data Previous tests: ECG stress test: No data Thallium/Stress echo: No data Left ventricular function: No data Echocardiogram: No data Coronary Arteriography: No data Baseline ECG: No data Holter Recording: Date: 14/02/1992 Recorder: No data ST ANNOTATIONS A.
