Significance of Holter Monitoring in Evaluation of Non-Specific Symptoms

Abstract

Background: To determine the diagnostic significance
of Holter monitoring in evaluation of non-specific
symptoms (like palpitations, dizziness, syncope,etc.).
Methods: In this descriptive study 100 consecutive
patients referred for the evaluation of non-specific
symptoms were selected for Holter monitoring after initial
evaluation. Through Holter monitoring two channels via
five leads, placed over the anterior chest wall, were
recorded. The disc was attached to a strap, which the
patient wore on his shoulder. The recording was usually
started in the morning at hospital and the patient was
allowed to resume his normal activities. He was advised to
maintain his activity log and asked to report back at the
same time next day.
Results: Ventricular ectopics less than 10% were
present as isolated events in 81%. Supraventricular
episodes less than 10% were present as isolated events in
93%.Mean minimum heart rate was 43 , mean maximum
heart rate was 123 and mean average heart rate was 71 . The
ST-segment shift was present in 21% of the population in
which 3% were ST-segment elevation and 19% were STsegment
depressions.
Conclusion: For the patients with non-specific
symptoms Holter monitoring has got an insignificant role,
in the primary diagnosis of myocardial ischemia or
arrhythmia as a cause of such symptoms.
