SUMMARY NOTES IN THE RECORD s20051 (Duration: 21:18:44.000) Starting time, recording date: 15/02/1994 Lead 0: ML2 Lead 1: MV2 Age: 87 Sex: F Comments: In this patient with RBBB and known left ventricular hypertrophy the transient ST changes noted are characterized by ST depression and downsloping which suggests ischemia. This record is from the initial Long-Term ST Database of eleven 24-hour ST annotated ambulatory records (record s19922). Symptoms during Holter recording: No data Diagnoses: Hypertension Treatment: Medications: Atenolol Hydrochlorothiazide Procardia XL Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: No evidence of coronary artery disease Hypertension: Yes Left ventricular hypertrophy: Yes Cardiomyopathy: No Valve disease: No Electrolyte abnormalities: No Hypercapnia, anemia, hypotension, hyperventilation: No Atrioventricular nodal conduction delay: No Intraventricular conduction block: Right bundle branch block Previous Myocardial Infarction: No Previous tests: ECG stress test: No Thallium/Stress echo: No Left ventricular function: Good left ventricular function Echocardiogram: Symmetrical left ventricular hypertrophy Good left ventricular function Coronary Arteriography: No Baseline ECG: Normal sinus rhythm Left ventricular hypertrophy Right bundle branch block Slightly long QT interval Holter Recording: Date: 15/02/1994 Recorder: No data ST ANNOTATIONS A.
