Bradycardia

Bradycardia is diagnosed through a physical exam, symptom review, and specialized tests.

Physical exam: Your healthcare professional listens to your heart with a stethoscope and asks about your symptoms and medical history.
Blood tests: Check for infections, electrolyte imbalances (like potassium), and thyroid function.
Electrocardiogram (ECG or EKG): Measures the electrical activity of the heart. Sticky patches with sensors are placed on the chest, arms, and legs, with wires connecting to a computer.
Holter monitor: A portable ECG device worn for a day or more to record the heart’s activity during daily activities.
Event recorder: Similar to a Holter monitor but records only when activated, usually for up to 30 days.
Tilt table test: Checks heart rate and blood pressure response when moving from lying down to standing, often used for fainting episodes.
Stress exercise test: Monitors heart activity during exercise or with medication that mimics exercise effects.
Sleep study: Recommended if obstructive sleep apnea is suspected, which can affect heart rhythm.

Treatment depends on symptom severity and underlying cause.

Lifestyle changes: Adjusting daily habits may help manage a slow heartbeat.
Medication adjustments: Some medicines can cause bradycardia. Your healthcare professional may lower the dose or change the medication.
Treating underlying conditions: Correcting issues such as thyroid disease or sleep apnea may resolve bradycardia.
Pacemaker: For severe bradycardia, a pacemaker may be surgically placed under the skin near the collarbone. It sends electrical signals to maintain a proper heart rate.

List symptoms, when they occur, and their severity.
Bring a complete medication list, including over-the-counter drugs and supplements.
Prepare questions for your healthcare professional about diagnosis, treatment options, and lifestyle considerations.
