   A stress test revealed he had atrial fibrillation, Afib for short, a heart condition involving irregular and often very rapid heart rhythm, which can lead to blood clots in the heart and increase ...

3. Atrial fibrillation - Wikipedia

   en.wikipedia.org/wiki/Atrial_fibrillation

   Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11 ][ 12 ] It often begins as short periods of abnormal beating, which become longer or continuous over time. [ 4 ]

4. Catheter ablation - Wikipedia

   en.wikipedia.org/wiki/Catheter_ablation

   Catheter ablation procedure involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein. The catheters are then advanced towards the heart. The catheters have electrodes at the tips that can measure the electrical signals from the heart.

5. Tachycardia-induced cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Tachycardia-induced_cardio...

   Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1][5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle ...

   Abnormal heart rhythms, or arrhythmia (also called irregular heartbeats), occur when the heart beats too fast, too slow, or irregularly, disrupting its normal function. They can be asymptomatic or ...

7. Left axis deviation - Wikipedia

   en.wikipedia.org/wiki/Left_axis_deviation

   Left axis deviation. The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.

8. Atrioventricular block - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_block

   Specialty. Cardiology. Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired. Normally, the sinoatrial node (SA node) produces an electrical signal to control the heart rate.

9. Restrictive cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Restrictive_cardiomyopathy

   Specialty. Cardiology. Restrictive cardiomyopathy (RCM) is a form of cardiomyopathy in which the walls of the heart are rigid (but not thickened). [2][3] Thus the heart is restricted from stretching and filling with blood properly. It is the least common of the three original subtypes of cardiomyopathy: hypertrophic, dilated, and restrictive.
