A cardiovascular block (often called a heart block or conduction block) is a condition where the electrical signals that control your heartbeat are slowed down or interrupted. These signals normally travel through the heart to keep it beating in a regular rhythm. When the pathway is blocked, the heart may beat too slowly, irregularly, or even pause.
First-Degree Block: The signal is slowed but still reaches the heart’s chambers. Often mild and without symptoms.
Second-Degree Block: Some signals don’t get through, leading to skipped beats.
Third-Degree (Complete) Block: No signals reach the lower chambers, causing the heart to beat dangerously slow.
Dizziness or fainting
Shortness of breath
Chest discomfort
Fatigue or weakness
Irregular or slow heartbeat
Cardiovascular blocks can range from harmless to life-threatening. Severe forms may reduce the heart’s ability to pump blood effectively, leading to serious complications if untreated.
Monitoring: Mild cases may only need regular check-ups.
Medications: To manage symptoms or related conditions.
Pacemaker: In more serious blocks, a small device is implanted to keep the heart beating at a healthy rhythm.
Early detection and treatment make a big difference. If you notice symptoms like fainting, extreme fatigue, or irregular heartbeat, medical evaluation is essential.
