SUMMARY NOTES IN THE RECORD s20441 (Duration: 23:47:00.000) Starting time, recording date: 09:44:00 08/01/1993 Lead 0: 0 Lead 1: 1 Age: 64 Sex: M Comments: Lead 0: There are 8 ischemic ST changes, generally associated with increases in heart rate. Lead 1: Fourteen episodes were present in this lead. NOTE - There is an axis shift in the QRS during the ischemic episode at 10:33:19, but it does not cause a significant ST change. Electrode locations were not recorded. Symptoms during Holter recording: No data Diagnoses: Coronary artery disease Treatment: Medications: Nitroglycerine Calcium blocker Aspirin Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: Previous myocardial infarction Hypertension: No 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: Yes Previous tests: ECG stress test: No data Thallium/Stress echo: No data Left ventricular function: No data Echocardiogram: No data Coronary Arteriography: Lesions in right coronary artery, left anterior descending coronary artery, left circumflex coronary artery Baseline ECG: No data Holter Recording: Date: 08/01/1993 Recorder: No data ST ANNOTATIONS A.
