Ambulatory monitoring: (Holter, event recorders, external, and implantable loop recorders and wireless technology)

Abstract

The cornerstone for the evaluation of unexplained syncope or palpitations is a comprehensive clinical evaluation combined with cardiac monitoring to establish an accurate symptom-rhythm correlate. There are many modalities of ambulatory outpatient monitoring, ranging from noninvasive Holter monitoring to implantable loop recorders. The choice of modality should be tailored to individual patients based on nature and frequency of symptoms.
