What is Holter Test?
A Holter monitor is a small, medical device that measures your heart’s activity, such as rate and rhythm for 24 hours. This device is connected to the electrodes and electrical leads, and even newer devices use only a single patch to detect hearts activity, which is more convenient to the patients.
