Sinus bradycardia is a type of heart rhythm disturbance in which the sinus node, located in the right atrium of your heart, fires at a slower-than-normal rate. This can cause your heart to beat fewer times per minute than normal (a condition called bradycardia) and may lead to symptoms such as dizziness, lightheadedness, or fainting. If you experience any of these symptoms, it’s important to seek medical attention right away. This article will discuss sinus bradycardia ECG and what you need to know about it.
An electrocardiogram (ECG) is a test used to measure your heart’s electrical activity. An ECG can help identify sinus bradycardia and other heart rhythm disturbances, such as atrial fibrillation or ventricular tachycardia. It is used to monitor your heart rate and rhythm and detect any abnormalities.
Sinus bradycardia occurs when the sinus node—the heart’s natural pacemaker—slows below the normal range of 60-100 beats per minute (bpm). The slow heart rate can cause lightheadedness, fatigue, and dizziness in sinus bradycardia. In more severe cases, sinus bradycardia can lead to fainting or cardiac arrest.
A sinus bradycardia ECG is used to diagnose sinus bradycardia and assess its severity. The test measures the electrical activity of your heart and is used to diagnose sinus bradycardia and other arrhythmias. The ECG will show a slow heart rate, abnormal P waves, and/or an abnormal PR interval.
Sinus bradycardia can lead to serious health complications, and an ECG is used to diagnose sinus bradycardia and assess its severity. It is important to consult a doctor if you experience any unusual heart-rate-related symptoms, such as dizziness or fainting. With proper diagnosis and treatment, sinus bradycardia can be managed with lifestyle changes and medications.
