Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Heart problems ventricular bigeminy?

Heart problems ventricular bigeminy?

Usually benign: Premature or "skipped" beats frome the bottom chambers of the heart are common; they sometimes occur in fixed patterns. When every other beat is a premature beat, it's called ventricular bigeminy. When every 3rd beat is premature, it's called ventricular trigeminy, and so on. Bottom line: with a normal heart, these patterns are completely benign and don't need treatment unless very troubling. ...Read more

What is Paroxysmal atrial fibrillation?

What is Paroxysmal atrial fibrillation?

Irregular pulse: Paroxysmal atrial fibrillation is an abnormal heart rhythm that is intermittent (or paroxysmal), arising from the upper chambers of the heart (or atria), and is very chaotic, or irregular (fibrillating). It can cause problems because it usually drives the heart rate up too fast (giving symptoms and eventually weakening the heart) and can increase the risk of stroke. Causes of PAF are multiple. ...Read more

What is worse: ventricular fibrillation or atrial fibrillation?

What is worse: ventricular fibrillation or atrial fibrillation?

Ventricular fib: Vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation, while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal. Additionally, if the af causes a fast pulse for a prolonged period of time, this may lead to weakening of the heart and cause heart failure. ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more

Is an irregular heart beat usually atrial fibrillation?

Is an irregular heart beat usually atrial fibrillation?

Not always: It certainly can be. Although there are multiple instances when one can have an "irregular heartbeat'. You should see your doctor so an ekg can be done or possibly a monitoring device ordered to evaluate further. ...Read more

Ventricular fibrillation fatal?

Ventricular fibrillation fatal?

Possibly..: In ventricular fibrillation, vfib, the heart is quivering and there is no blood flow so the person is clinically dead. If the heart cannot be restored to a rhythmn where there is blood flow, the patient will then be pronounced dead. Treatment for this rhythmn includes electrically shocking the heart as quickly as possible. Performing CPR in the meantime can be life-saving. ...Read more

Is atrial fibrillation inherited?

Sometimes: There is a gene that makes the tendency to get it more likely, but most a fib is due to environmental and aquired factors such as age, valvular heart disease and alcohol. ...Read more

Compare ventricular vs supraventricular tachycardia?

Compare ventricular vs supraventricular tachycardia?

Atria or ventricles: Supra ventricular tachycardia: from upper chambers of the heart, is due to irritability (increased automaticity) or a short circuit (reentry), heart is usually structurally normal. Ventricular tachycardia: from lower chambers of the heart, due to irritability, can occur in normal hearts but is more often seen in hearts with scar tissue or weak hearts and can be life threatening. ...Read more

Would an echocardiogram detect an atrial fibrillation?

Would an echocardiogram detect an atrial fibrillation?

Yes: Although an echocardiogram can detect atrial fibrillation, there are easier ways to diagnose it. Your doctor should be able to tell if your pulse is irregular and confirm afib with a simple ekg. Atrial fibrillation sometimes makes interpretation of an echocardiogram more difficult if the heart rate is too fast. ...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 causes pulseless ventricular tachycardia?

What causes pulseless ventricular tachycardia?

Not really pulseless: When VT occurs at a fast enough rate, there is inadequate time for ventricular filling, cardiac output falls, and blood pressure falls. You may not be able to palpate a pulse but an arterial line would show a waveform that is reduced in amplitude. Rate is the key. As tissue perfusion fails, acidosis, hypoxemia and hyperkalemia result leading to ventricular fibrillation and death. ...Read more

A recent electrocardiogram revealed an enlarged left atrium. I'm only 25 but heart disease runs in my family. How serious of a condition is this?

A recent electrocardiogram revealed an enlarged left atrium. I'm only 25 but heart disease runs in my family. How serious of a condition is this?

Depends: There are 2 question: is the atrium truly enlarged and, if so, is there a reason for it: both can be answered with an echocardiogram. Usual reasons for left atrial enlargement are: hypertension, left ventricular diastolic dysfunction, atrial fibrillation, mitral valve disease, and atrial septal defect. The EKG is very indirect. The echo is much more accurate as it directly measures LA size. ...Read more

Atrial Septal Aneurysm (Definition)

The atrial septum devides the right atrium (upper heart chamber) from the left. During developement in the womb, there is a large opening in this wall which closes soon after birth. The closure can be floppy or redundent, and may be referred to as aneurysm. This is benign and not the type of aneurysm that needs repair or is ...Read more

Atrial Septal Defect Repair (Definition)

An atrial septal defect is a congenital defect of the heart. A hole in the wall between the left and right atria permits blood to mix. There are several types of asd's and depending on the type and size they can either be closed with closure device placed thru the veins or by heart surgery ...Read more
