Diagnosing Bigeminy
Bigeminy is a specific type of heart arrhythmia where the heart beats in a repeating pattern of one normal beat followed by an abnormal beat and a pause. To diagnose bigeminy, doctors may perform several examinations, screening tests, and procedures. These help confirm the diagnosis and determine the type, severity, or stage of bigeminy. Specialists who may be involved in diagnosing bigeminy include cardiologists and electrophysiologists.
Here are the examinations, tests, and procedures commonly used to diagnose bigeminy:
- Physical examination: During a physical examination, a doctor will listen to the heart rate and rhythm. They may also check for signs of heart failure, such as swelling or edema. Additionally, they will take the pulse and blood pressure readings.
- Electrocardiogram (ECG): An ECG is the main test used to diagnose bigeminy. It involves placing electronic sensors on the chest to painlessly record the electrical activity of the heart. The recorded information reveals the pattern of heartbeats and can often identify the source of the unusual heart rhythm.
- Exercise stress test: In some cases, a doctor may recommend an exercise stress test. During this test, you will walk on a treadmill or ride a stationary bike while hooked up to an ECG machine. This helps your doctor determine the severity of your bigeminy. If your premature contractions disappear during exercise, they are probably not a threat. However, if physical activity triggers additional beats, it could be a sign of a more serious heart rhythm disturbance.
- Holter monitor or event monitor: If an ECG does not catch the abnormal heart events associated with bigeminy, a doctor may suggest wearing a Holter monitor or event monitor for a longer period of time. These devices continuously monitor your heartbeat to capture any irregularities that may occur throughout the day.
Additional tests: Depending on individual circumstances, doctors may order additional tests to confirm the diagnosis or rule out other possible causes. These tests may include:
- MRI (Magnetic Resonance Imaging): This test uses powerful magnets and radio waves to create detailed images of your heart.
- CT scan (Computed Tomography scan): A CT scan uses specialized X-ray equipment to produce cross-sectional images of your body.
It's important to note that if you experience symptoms like palpitations or skipped heartbeats, it is crucial to contact your doctor for evaluation. While some cases of bigeminy are benign and transient, severe or frequent episodes may require further investigation by a healthcare professional specializing in heart conditions. They can provide appropriate guidance and develop a treatment plan tailored to your specific needs.
