Some episodes trigger the ischemic # episode definition during the ST elevation, while # others trigger only at the onset of ST-depression. # In still other cases there is a short interval of # "near-baseline" ST between the elevations (peaking # of Ts) and depressions which causes a double counting # of the biphasic episode as two separate episodes. # This occurs at: 6:41:32, 16:48:58, 18:33:00, # 21:21:48, 21:36:10 and 23:36:22. # Physiologically each of these represents a single # episode of ischemia. At 15:18:52, there is a short # axis shift which interrupts the terminal portion of # an ischemic episode, resulting in artifactual early # termination of the ischemic episode, and the definition # of a second episode. # Lead 1: # At approximately 6:41:36 the terminal portion of the # ischemic episode is split into additional episodes - # but all represent the resolution phase of the ischemic # episode. T wave peaks, T-wave peaking decreases, and # finally ST depression resolve. # At 7:21:20, double positive peak in ST trend at beginning # of this episode is created by the superposition of # rate-related ST-depression. At 15:18:52, see note above # for lead 0. At the end of this record the data has a # number of episodes labeled as "rate-related". # At 16:52:48, axis shift annotation set between the end # of ischemic episode and local reference. # Electrode locations were not recorded. #Symptoms during Holter recording: No data #Diagnoses: # Coronary artery disease #Treatment: # Medications: # Isordil # Nitroglycerine # Calcium channel blocker # Aspirin # Balloon Angioplasty: Yes # Coronary Artery bypass Grafting: No #History: # Angina # Hypertension: No # Left ventricular hypertrophy: No # Cardiomyopathy: No # Valve disease: No # Electrolyte abnormalities: No # Hypercapnia, anemia, hypotension, hyperventilation: No # Atrioventricular nodal conduction delay: No data # Intraventricular conduction block: No data # Previous Myocardial Infarction: No # Previous tests: # ECG stress test: No data # Thallium/Stress echo: No data # Left ventricular function: No data # Echocardiogram: No data # Coronary Arteriography: # Lesions in left anterior descending coronary artery, left circumflex coronary artery # Baseline ECG: No data #Holter Recording: # Date: 27/05/1992 # Recorder: No data
