SUMMARY NOTES IN THE RECORD s30681  (Duration: 23:39:35.984)

Starting time, recording date:  11:35:00 14/01/1999

Lead 0: V6
Lead 1: II
Lead 2: V5

Age: 71  Sex: M
Comments: 
  Patient with CAD and hypertension has many episodes
  of ST depression recorded simultaneously on all
  leads. The ST segments are associated with heart
  rate increases, and with different ST shape. Most
  are J-point depressions with up-sloping ST segments,
  but a very convincing episode occurred at the end of
  the recording period with clearly ischemic, down-sloping
  ST segments.
Symptoms during Holter recording: None reported
Diagnoses: 
  Coronary artery disease
  Mild hypertension
Treatment:
  Medications: 
    Nifedipine
    Atenolol
    Procardia

  Intraventricular conduction block: No data
  Previous Myocardial Infarction: No
  Previous tests:
    ECG stress test: Yes
      Date: 1983
      Findings: ST depression >2mm, peak HR=136. ST changes in leads II, III, V3-V6
