Sinus bradycardia ECG is an electrocardiogram ECG that shows a slower than normal heartbeat. An ECG is a test used to measure the electrical activity of the heart. It looks like a graph with waves that show each part of the heartbeat. A sinus bradycardia ECG can help detect heart problems or diseases.
A normal resting heart rate for adults is between 60-100 beats per minute BPM. When someone has sinus bradycardia, their heart rate drops below 60 BPM and can be as low as 30 BPM or even lower in some cases. This type of slow heartbeat occurs when something disrupts the electrical signals that control your heartbeat and cause it to become too slow.
There are several potential causes of sinus bradycardia, including medical conditions such as hypothyroidism, anemia, and certain medications like beta blockers and calcium channel blockers; other causes include age-related changes in your cardiovascular system or physical exhaustion due to exercise or stress.
If you experience any symptoms such as chest pain, dizziness, palpitations a feeling of skipped beats, fainting spells, shortness of breath or fatigue then you should see your doctor immediately for evaluation and testing to determine if you have sinus bradycardia ecg or another underlying condition causing these symptoms.
