Holter monitor
Wireless Ambulatory ECGs are able to provide voice alarm messages when cardiac abnormalities occur, such as bradycardia, and can record this information and provide a screen prompt for the patient to view the data. The devices can also store mass amounts of ECG data on the phone, replay the ECG readings at a high speed, and have a low voltage alarm function to not waste the battery life. These characteristics of the devices are seen as benefits in comparison to current ambulatory ECG monitoring equipment such as the Holter monitor.
