What is atrial fabrillation?

What is atrial fabrillation?

Abnormal rhythm: Atrial fibrillation (af) is a heart rhythm problem due to disorganization of the electrical activity in the atria (upper heart chambers). Af is the most common heart rhythm disorder. Patients with af may have no symptoms or may have symptoms such as decreased energy, palpitations, or heart failure. Af also increases the risk of stroke. Various therapies may be used to treat af and stroke risks. ...Read more

What is arrythmia?

What is arrythmia?

Abnormal heart beat: It is irregular heart beat menifested by slow heart rate, fast pulse, skip beat or palpitation. Usually the adult heart beats 60to 100 during the day. Below 60 bradycardia, above 100 tachycardia. If beating at the same rate interval-regular. If the interval varies-irregular. Coming from atria-atrial & from ventricle-ventricular. Simple version. Medically many terms for them. No space here. Thanks. ...Read more

What is atrial fibrillation? Is it serious?

Depends: Atrial fibrillation is a very common arrhythmia, often unclear in origin, but usually due to enlarged upper heart chambers (atria). High blood pressure, heart valve problems, heart failure, hyperthyroidism, coronary disease, alcohol, or even spontaneous in normal people. Some drop in energy may be noted, but one can live normally with it. Blood thinners to minimize strokes important if persists. ...Read more

What is atrial fibrillation?

Irregular rhythm: Af is an irregular heart rhythm caused by uncoordinated electrical activity in the atria, or top chambers of the heart. Sometimes it is fast, other times it isn't. ...Read more

What is atrial fibrillation?

What is atrial fibrillation?

Arrhythmias: Atrial fibrillation (afib) is the most common sustained rhythm abnormality. It's characterized by an irregular heart rate. The upper chambers of the heart (atrium) do not beat but quiver. Many people don't notice it. But many do. It can lead to strokes in some patients so blood thinners are important. It can be treated with medications, ablation thru iv's in the groin or surgery. See a cardiologis. ...Read more

What is tachycardiac?

Tachycardia: Tachycardia is an overly rapid heart rate. Resting heart rate for an adult is usally 60 - 100 beats per minute. Tachycardia may or may not cause symptoms. ...Read more

What is cardiomyospathy?

What is cardiomyospathy?

3 types: There are 3 types of cardiomyopathy: dilated, hypertrophic, and restrictive. All are diseases of the heart muscle (as opposed to the arteries, valves, or conducting system). Excess alcohol (which you list) is a known cause of dilated cardiomyopathy in which the heart muscle becomes weak and pump function is impaired. It's reversible early on by stopping (not reducing) drinking. ...Read more

What is cardiomypathy?

What is cardiomypathy?

Various causes: Cardiomyopathy is a generic term for abnormal heart muscle. It can be caused by infections, poisons, genetics, and physiologic causes. There are both weak heart and 'strong heart' cardiomyopathies. The cause of someone's cardiomyopathy requires more information than the term cardiomyopathy. ...Read more

What is defibrillation for tachycardia?

What is defibrillation for tachycardia?

Not defibrillation: Defibrillation is an unsynchronized electrical shock to the chest for ventricular fibrillation, not for tachycardia. Tachycardia is treated with drugs or synchronized cardioversion (a shock applied at the exact moment in the cardiac cycle that is safe). The shock makes all the muscle cells begin their cycle freshly at the same moment, kind of like re-booting your computer! ...Read more

What kind of ventricular fibrillation is not dangerous?

What kind of ventricular fibrillation is not dangerous?

Ventricular fibrilla: Ventricular fibrillation means the heart is not mechanically contracting and thus isn't pumping blood. There is no kind of ventricular fibrillation that isn't life threatening unless it is the kind which is pseudovfib meaning it isn't really fibrillating, it just looks that way on the ecg. ...Read more

What is dextocardia?

What is dextocardia?

Right sided heart: Dextrocardia is a congenital (present at birth) condition in which the heart is situated on the right side of the body instead of the normal left side. There are different types of dextrocardia-sometimes the heart is entirely normal except for its location, other times there are associated heart defects. Sometimes the organs of the abdomen are also reversed. ...Read more

What is systole?

What is supraventricular tachycardia? Is it serious?

What is supraventricular tachycardia? Is it serious?

See below: Supraventricular tachycardia (svt) is an episodic fast heart rate that usually originates in the upper chambers of the heart. It usually starts all of a sudden and stops all of a sudden, usually is not life threatening by itself, and is mostly rather easily treatable with a cardiac procedure called ablation which is performed by an electrophysiologist. ...Read more

What is heart ablation?

What is heart ablation?

RFA: By this, i assume you mean radiofrequency ablation or rfa procedures. These are highly specialized electrophysiology procedures used to treat specific heart rhythm disturbances (arrhythmias). It is carried out much in the same way as a heart catheterization except the heart's electrical activity is mapped and abnormal rhythms are treated with radiofrequency energy through special catheters. ...Read more
