Holter monitor
A holter monitor or ambulatory electrocardiography device is a portable equipment that is used to monitor electrical activity of the heart. There are a series of electrodes attached to the chest of the patient that can record electrical signals from the heart. There is a recording monitor that can be carried in the pocket or worn around the neck. The patient's EKG for 24 hours is recorded. Values such as average heart rate, maximum and minimum heart rate are calculated. ECG tracing using Holter monitor is conducted on patients who suffer prolonged fatigue and episodes of low blood pressure and fainting.
A Holter monitor aids in recording any abnormal activity of the heart. The Holter monitor is worn by the patient as he/she goes about his daily routine. It is possible to observe occasional cardiac arrhythmias, atrial fibrillation and atrial tachycardia with a Holter monitor. This device is also adviced for patients who have suffered a heart attack or under cardiac medication. A Holter monitor aids in monitoring the performance of a heart pacemaker. Smoking and close proximity to devices such as magnets and metal detectors and some electrical appliances can affect the Holter monitor readings.
