Arrhythmia : Causes, Symptoms and Treatment

An arrhythmia occurs when the electrical impulses that coordinates your heartbeats don't work properly, resulting in your heart to beat too fast, too slow or abnormally. The condition may feel like a racing heart and may be undamaging. <br>

  1. Arrhythmia(Irregular Heartbeat) CAUSES | SYMPTOMS | TREATMENT

  2. INTRODUCTION TO ARRHYTHMIA • An arrhythmia occurs when the electrical impulses that coordinates your heartbeats don't work properly, resulting in your heart to beat too fast, too slow or abnormally. The condition may feel like a racing heart and may be undamaging. However, some heart arrhythmias may lead to life-threatening symptoms. • An arrhythmia is a problem with the rate or rythm of the heartbeat (irregula heartbeat). During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. • A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia.

  3. CAUSES OF ARRHYTHMIA • Coronary artery disease • High blood pressure • Changes in the heart muscle (cardiomyopathy) • Valve disorders • Electrolyte imbalances in the blood, such as sodium or potassium • Injury from a heart attack • The healing process after heart surgery • Other medical conditions • Hypertension • Excessive stress

  4. CAUSES OF ARRHYTHMIA An arrhythmia doesn’t usually cause any symptoms. But gradually, it may show certain signs including: A fluttering in your chest • A racing heartbeat • A slow heartbeat • Chest pain • Shortness of breath • Light-headedness or dizziness • Sweating • Fainting (syncope) or near fainting

  5. TEST AND DIAGNOSIS OF ARRHYTHMIA • ECG: During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes to your limbs. An ECG measures the timing and duration of each electrical phase in your heartbeat. • Echocardiogram: In this non-invasive test, a hand-held device (transducer) placed on your chest uses sound waves to produce images of your heart's size, structure and motion. • Implantable loop recorder: This device detects abnormal heart rhythms and is implanted under the skin in the chest area.

  6. CONTINUE :-TEST AND DIAGNOSIS OF ARRHYTHMIA • Electrophysiological testing and mapping: In this test, doctors thread thin, flexible tubes (catheters) tipped with electrodes through your blood vessels to a variety of spots within your heart. Once in place, the electrodes can map the spread of electrical impulses through your heart. • Stress Test: During a stress test, you'll be asked to exercise on a treadmill or stationary bicycle while your heart activity is monitored. If doctors are evaluating you to determine if coronary artery disease may be causing the arrhythmia, and you have difficulty exercising.

  7. TREATMENTS OF ARRHYTHMIA Usually, treatment for an arrhythmia is required only if the arrhythmia is causing significant symptoms or if it's putting you at risk of a more serious arrhythmia or arrhythmia complication.  • Treating slow heartbeats: If slow heartbeats don't have a cause that can be corrected, doctors often treat them with a pacemaker because there aren't any medications that can reliably speed up your heart. • Treating fast heartbeats: For fast heartbeats, treatments may include vagalmanoeuvres, medications, cardioversion, and catheter ablation.
