Holter

Holter (ambulatory ECG) is a test to obtain 24 or 48 hour ambulatory ECG. If you have symptoms like palpitation or syncope (loss of consciousness) , you will first undergo an ECG test but most of time, at the time of ECG performance, you may not have any symptom and ECG may be normal. In such condition if holter is applied, 24 hour continuous ECG will be recorded and further analyzed with a software in computer for detailed evaluation of ECG. If you have any symptoms during 24 hour holter application, then ECG exactly at that moment will be reviewed from recorded device and will be correlated to your symptom. Your cardiologist will be in position to say you confidently whether your symptoms are because of heart problem or something else. Common indication of holter are palpitation or syncope (loss of consciousness) and abnormalities in ECG, impaired heart function (low ejection fraction).
