Exams and Tests
A doctor will listen to your heart with a stethoscope and feel your pulse. Your blood pressure may be low or normal.
The following tests may be performed to identify arrhythmias:
- ECG
- Ambulatory cardiac monitoring with a Holter monitor (used for 24 hours) or loop recorder (worn for 2 weeks or longer)
- Echocardiogram
- Electrophysiology study (EPS)
- Coronary angiography
If an arrhythmia is detected, various tests may be done to confirm or rule out suspected causes. EPS testing may be performed to locate the origin of the arrhythmia and determine the best treatment, especially if a pacemaker implantation or catheter ablation procedure is being considered.
