SUMMARY NOTES IN THE RECORD s30691 (Duration: 23:50:59.984) Starting time, recording date: 10:59:00 24/03/1999 Lead 0: E-S Lead 1: A-S Lead 2: A-I Age: 81 Sex: F Comments: Increases in heart rate lead to ischemic ST changes. Patient has coronary artery disease and angina by history. The ECG changes are best seen in lead 1 and lead 2. The changes in lead 0 are of much smaller amplitude, and often do not reach criteria for significance. Symptoms during Holter recording: None reported. Diagnoses: Coronary artery disease Labile hypertension Palpitations Treatment: Medications: Atenolol Vasotec Balloon Angioplasty: No Coronary Artery bypass Grafting: No History: Hypertension: Yes Left ventricular hypertrophy: Mild 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: No Thallium/Stress echo: No Left ventricular function: Normal Echocardiogram: Mild left ventricular hypertrophy, normal left ventricular function Coronary Arteriography: No Baseline ECG: Normal Holter Recording: Date: 24/03/1999 Recorder: Zymed ST ANNOTATIONS A.
