SUMMARY NOTES IN THE RECORD s20131 (Duration: 20:55:10.000) Starting time, recording date: 13:43:00 17/05/1995 Lead 0: ML2 Lead 1: MV2 Age: 82 Sex: F Comments: Lead 0: From 18:15:06 to 20:17:20 This entire period shows ST-T changes suggestive of ischemia, with a number of transient episodes of worsening ischemic ST depression. Lead 1: This lead shows ST changes during heart rate increases which show only minimal T-wave peaking not suggestive of ischemia, and they are therefore labeled as "rate-related". This record is from the initial Long-Term ST Database of eleven 24-hour ST annotated ambulatory records (record s21067). Symptoms during Holter recording: Chest pain Diagnoses: Inferolateral myocardial infarction 3-vessel coronary artery disease Left ventricular diastolic dysfunction Treatment: Medications: Aspirin Diltiazem Isosorbide Lisinopril Toprol Zantac Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: Coronary artery disease, hypertension Hypertension: Yes 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: Myocardial infarction in June 1995 Previous tests: ECG stress test: No Thallium/Stress echo: No Left ventricular function: Normal Echocardiogram: Mild aortic regurgitation Normal left ventricular function Coronary Arteriography: Severe 3-vessel disease, mid left anterior descending coronary artery total occlusion, moderately severe left ventricular diastolic dysfunction Baseline ECG: Normal sinus rhythm Qs in I, avL, V5,V6 Holter Recording: Date: 17/05/1995 Recorder: No data ST ANNOTATIONS A.
